"The more you use it, Research Could Reduce Transportation Project Costs Page 4 The Virginia Engineer March 2006 Virginia’s Engineering Address - www.vaeng.com the cheaper it becomes." Comparitively, the cost of steel over the same time period has more than doubled. Prof. Frosch worked with doctoral student Cihan Pay, who recently graduated, to analyze how well the new synthetic bars perform. As the bars are embedded lengthwise inside concrete structures, they often have to be spliced by overlapping the bars. "We call this overlapping the splice length of the bars," Prof. Frosch explains. "The longer the splice length, the greater amount of force the beam can withstand before it breaks." The researchers are studying how much splice length is needed for specific applications, using hydraulic machinery to exert force on test beams until they fail. "We're studying a range all the way from 12 inches up to about 54 inches of splice length," Prof. Frosch says. The research is funded by the Federal Highway Administration (FHA) through the Joint Transportation Research Program of Purdue and the Indiana Department of Transportation and is being conducted at Purdue's Robert L. and Terry L. Bowen Civil Engineering Laboratory for Large Scale Research. Data collected from the experiments will yield important information about how much force the bars can withstand when different splice lengths are used. A portion of Dr. Pay's research delved into the fundamental physics of how the concrete bonds to the overlapping bars. He used data from the research to develop mathematical equations for a new "fundamental model" that describes the precise performance characteristics depending on different splice lengths. "Bond failure is very bad," says Dr. Pay. "When it happens, there is no warning. People have no time to react." The model may be used in the future by the American Concrete Institute in new guidelines for the design and construction of concrete structures with fiber-reinforced polymer bars. "These are the guidelines for how engineers design structures using these bars," Prof. Frosch said. "The report will contain a chapter on splices and development of reinforcement." According to Dr. Pay, his equation for bond strength will apply to all materials, including steel bars. "It's going to be one simple equation that works across the board," he said. Sensors have been inserted in the deck of the Thayer Road bridge to constantly record data that will be used to learn how well the structure is performing. The data can be remotely monitored from Purdue. "Strain gauges provide a tool to measure the amount of stress in the bars," Prof. Frosch said. "Gauges are attached inside the bridge deck as well as on the girders under the deck." The researchers eventually will publish papers detailing how the bridge deck responds when subjected to actual traffic. Several states have built bridges with fiber-reinforced polymer bars, but the material is still considered experimental and is not in widespread use. Prof. Frosch said new research will provide a means for increased use of these materials. The cost alone, not to mention the disruption, of replacing bridges damaged as a result of some catastrophic event, natural or manmade, is staggering. An earthquake engineer at the University at Buffalo (UB) has developed a new “multihazard” design for bridges that will make them more resistant to terrorist attacks and earthquakes. The new structural design for bridge piers developed by Michel Bruneau, director of the Multidisciplinary Center for Earthquake Engineering Research (MCEER) at UB, will protect bridges from both seismic and blast forces, helping to keep them from collapsing in the event of earthquake or terrorist attack. “Since many bridges are, or will be, located in areas of moderate or high seismic activity, and because many bridges are potential terrorist targets, there is a need to develop Virginia’s Engineering Address - www.vaeng.com March 2006 structural systems capable of performing equally well under both events,” says Bruneau, a professor in the Department of Civil, Structural and Environmental Engineering in the UB School of Engineering and Applied Sciences. Prof. Bruneau’s design for bridge piers — the columns that support the bridge superstructure — is intended for small- and mediumsized bridges commonly constructed over major highways or across bodies of water. As targets for terrorist attacks, these bridges may not have the symbolic allure of the Brooklyn Bridge or the Golden Gate Bridge, but they could be targeted because of the potential economic disruption their collapse would cause, Prof. Bruneau notes. “There is a lot of interest in protecting large, monumental bridges. However there are other bridges that are extremely important as lifelines to large cities,” he says. “Terrorists may not achieve the same symbolic satisfaction taking down one of these smaller bridges as they would a monumental bridge, but if their objective is to disturb the economy, they have more access to these bridges than the monumental bridges.” Prof. Bruneau’s bridge-pier design uses corrosion-resistant steel tubes filled with concrete, but without reinforcing bars. The steel and concrete bind together, forming a composite structure, which gives the piers superior strength and ductility — meaning the piers will bend without breaking when subjected to significant blast and seismic forces. For the bridge pier’s footing, additional structural shapes are embedded in concrete to resist the large flexural (bending) forces developing at the base of the bridge piers. Most bridges built today are supported by conventional reinforced concrete columns. These columns likely would breach, leading to bridge collapse in the event of a major blast, Prof. Bruneau says. Prof. Bruneau’s bridge-pier design had been shown previously to provide adequate seismic protection, but had not been tested for blast resistance until recently.

The simplistic answer would be to replace them with newer, better designed structures. But this approach ignores the reality of the enormous amount of time, the staggering amount of money, and the scope of the labor effort which would be required to complete the task. The existing approach, involving largely ineffectual but very costly efforts to patch up and make do, has not proved to be the solution either. So, what is the solution? Well, according to one University of Wisconsin professor, the answer may well be a bandaid. Long polymer "bandages," designed initially to enable troops to quickly and easily repair or reinforce bridges to bear the weight of 113-ton military tank transport vehicles, now could be used to quickly and inexpensively strengthen aging rural bridges and concrete culverts around the country. With initial funding from the Army Corps of Engineers, Lawrence Bank, professor of civil and environmental engineering professor at the University of Wisconsin-Madison (UW-Madison), and his then-student Anthony Lamanna, perfected these bandages, or fiber-reinforced polymer (FRP) strips. Subsequently they patented the strips through the Wisconsin Alumni Research Foundation. In wartime, the strips could be key to keeping important transportation routes available, noted James Ray, a structural engineer for the U.S. Army Engineer Research and Development Center. "The main thing these strips would be used for is if the bridges don't have sufficient capacity to start with," he said. "The military loadings are very heavy compared to what bridges are normally designed for." Using fiber-reinforced composite strips to bolster concrete structures isn't a new concept. Bridge repair crews have been gluing them in place for more than a decade. Unfortunately, the process of transforming the crumbly, cracked and pockmarked underside of a de- cades-old concrete bridge into a surface suitable for glue takes good weather, a lot of time and, typically, a great deal of labor. "You have to sandblast; you have to repair with a mortar," explained The fiber-reinforced polymer strips developed to reinforce aging bridges by civil and environmental engineering professor Larry Bank require little preparation, effort and time to install. Here, Dave Winke and Frank Schneider from the Rock County, WI, Public Works Department and then-student Andrew Kuether (MS '03) mechanically fasten the strips to the underside of the Stoughton Road Bridge in rural Edgerton, WI. Before the city replaced the reinforced bridge in 2003, workers and UW-Madison researchers conducted a variety of tests to determine what loads would make it fail. Photo copywrite 2006 The Board of Regents of the University of Wisconsin System. Prof. Bank. "Typically on bridges, you're doing things overhead, which is also unpleasant." Mimicing a practice common in the building trades, an obvious alternative seemed to be simply fastening the strips to the bridge using a tool similar to a power nailer. The problem, however, was that existing strips, which contain only longitudinal fibers, wouldn't hold up when the fasteners punctured them. In much the same fashion as a dry board cracks or splits along the grain when a nail hits the wrong place, the fasteners caused the strips to split along the longitudinal fibers. "When you attach with fasteners, you have to have different properties in the strip," explained Prof. Virginia’s Engineering Address - www.vaeng.com March 2006 Bank. "You have to have high bearing strength - which is that you could press on the strip with these fasteners and it's not going to crack and split." Strongly resembling duct tape without the stick, the reinforcing strips developed by Prof. Bank and Mr. Lamanna combine carbon fibers, glass fibers and glass mats. The mats, which are woven in tight crisscrosses as opposed to containing only longitudinal fibers, are key to the new strips' success. "If you make a hole in the strip and you push on the hole, the weave allows it to carry that load," Prof. Bank said. "If you just have these longitudinal fibers, if you make a hole and you push on it, it's going to slide." The newly developed strips, which are stiff but not rigid, act like super-strong bandages that workers can quickly and inexpensively attach to the underside of a bridge with powder-actuated concrete fasteners. To test the strips, county workers installed them on the decaying 1930s Stoughton Road bridge in Edgerton, WI, in 2002. "It was really bad," said Tom Hartzell, Edgerton public works director. "There were some big cracks that went all the way through." During the installation, which took three workers less than a day, a thunderstorm whipped up. The bridge was in such poor condition that rainwater and run-off poured through the cracks. "You cannot use a technique where you bond on strips in that environment," Prof. Bank emphasized. Total cost for strengthening the bridge was about $8,000; eventually, Edgerton replaced it at a cost of $196,800, including plan development, state review, old bridge removal and new bridge construction. Continued research and development of new materials and construction techniques will hopefully be instrumental in creating new opportunities to help make existing funding available for other transportation projects. Solving the problem of what to do about America’s crumbling transportation infrastructure may well depend upon it. ## The Virginia Engineer Page 7 Report Assesses Impact Of Road Development On Natural Environment The National Academy of Sciences’ (NAS) has issued a new report entitled “Assessing and Managing the Ecological Impacts of Paved Roads.” The report is the broadest study to date examining how road development in the United States affects the natural environment, focusing specifically on wildlife habitats. The 250-page report serves as a virtual road map for state and local highway authorities, as well as engineering and construction companies, to work in concert with environmental groups on highway development. Despite more than four million miles of paved roads in the United States, the country is in the midst of a capacity shortage. Federal and state governments forecast the need for additional highway construction, particularly in suburban and exurban areas where it will greatly impact wildlife ecosystems. Because no single law exists addressing ecological concerns for transportation projects, there is wide discrepancy on how to balance environmental concerns and road planning. Since the mid-1990s, several federal transportation statutes have directed national and state highway authorities to adopt a more sensitive approach to the environment, particularly with respect to wildlife habitat disruption caused by new roads. Now, with an increasing amount of federal money being directed to new highways, ecological concerns become more important than ever. “Although a wide range of laws, regulations, and policies require that new road construction take in some consideration of wildlife impact, the existing legal structure leaves significant gaps,” according to Margaret Strand, a partner with Venable LLP’s Transportation and InfrastrucPage 8 The Virginia Engineer ture practice. “This report represents an important consensus from some disparate and often opposed stakeholders – in particular, state and federal highway authorities and conservation groups. We think it will serve as a handbook for ecologically minded road construction for years to come.” Ms. Strand authored the chapter in the NAS report that provides a legal context for road planning and policy and she contributed significant portions to other chapters. Joining her on the NAS committee were a number of prominent researchers and professionals from the transportation and environmental fields, including representatives from the Wildlife Conservation Society, Western Transportation Institute and the Oak Ridge National Laboratory. The report's recommendations focus on the need for integration of ecological considerations in all phases of road development, including maintenance of existing roads. The study’s key recommendations include: • The establishment of a set of rapid screening and assessment methods for environmental impacts of transportation and a national ecological database. March 2006 • A national effort to develop standards for data collection. • Improved models to predict how roads will affect environmental conditions. • Development of an environmental information and decision support system by federal and state transportation agencies. • Better collaboration among transportation and natural resource planners to support mutual objectives. Ms. Strand was uniquely qualified to contribute to the NAS report, bringing a rare combination of exceptional credentials in both transportation and the environment. She recently served as Special Assistant Attorney General to the State of Utah in order to negotiate a settlement with the Sierra Club and other conservation groups that allowed for the construction of the new Legacy Parkway along the shores of the Great Salt Lake. From 1984 to 1991, she was Chief of the Environmental Defense Section in the U.S. Justice Department, Environmental and Natural Resources Division. Ms. Strand has served on the Environmental Law Committee of the Transportation Research Board, National Academy of Sciences since 2002 and was a member of the National Academy of Sciences Board on Environmental Studies and Toxicology from 1993 through 2001. She has also authored numerous works on environmental law issues including the Wetlands Deskbook (Environmental Law Institute, 1993, 1997). “We think the new report represents a turning point. It represents a meeting of the minds that accommodates both the need for highway expansion with the need for habitat protection,” said Ms. Strand. “There are so many stakeholders whose interests need to converge in order to achieve the best approach to well-planned road development – state and local highway authorities, engineering and construction firms, trucking companies, as well as the millions of Americans who traverse the country’s highways every day.” ## Virginia’s Engineering Address - www.vaeng.com Over 150 Candidates Pass PE Exam Over 150 candidates from Virginia successfully passed the October 2005 Professional Engineer licensing exam.

The device could save truck operators $4,000 per year. ics,” explained Ken Visser, associate professor of Aeronautical and Mechanical Engineering. “Traditional transport vehicles have a flat aft end that creates a large drag on the vehicle at highway speeds, which ultimately reduces gas mileage and increases costs and emissions. We have designed extendable flat plates that can be mounted to the truck’s rear doors to reduce drag.” The device, which resembles a second set of doors when closed and opens out into a box-like structure, has been studied in Clarkson’s wind tunnel as well as on full-scale vehicles in cross-country road tests. “The most recent data based on road testing indicates that the device will save approximately onehalf mile per gallon, an increase in fuel efficiency of about 10 percent,” said Prof. Visser. “This translates into a savings of about $4,000 per year for a truck running 150,000 miles at $2.50 a gallon of fuel.” Prof. Visser and his team of graduate and undergraduate student researchers tested various shapes and created a prototype in 2000. After developing the technology and design, he was awarded a grant from NYSERDA and contracted with the Plattsburgh, N.Y.,-based company Composite Factory Inc. to manufacture the device using efficient lightweight composite materials. A design patent for the unique concept is currently in the works. The next step is a 50-truck fleet test. “Once we can test run this on a larger scale we will really be able to quantify the fuel savings and environmental benefits,” said Prof. Visser. ## Virginia’s Engineering Address - www.vaeng.com NASA Continues Exploration Of Scientific Frontier The science is tiny as carbon nanotubes and the silica shells that cover single-cell algae. And it’s as practical as finding a leak in a spacecraft and understanding a new material for the next space telescope. Researchers affiliated with Iowa State University’s Center for Nondestructive Evaluation are working on 17 projects for the National Aeronautics and Space Administration. The work is in its fourth year and is focused on finding new materials to monitor the health and safety of spacecraft and developing new methods for inspecting spacecraft. The research projects are supported by $7 million appropriated by Congress from 2002 to 2005. “This research is laying the foundation for the future,” said R. Bruce Thompson, an Iowa State Anson Marston Distinguished Professor in Engineering and director of the Center for Nondestructive Evaluation. “Space is a whole new area to apply our toolbox and develop new tools.” Here are four examples of the research Iowa State scientists are doing for NASA: • Leak detection It’s not easy to find a leak in a spacecraft. The leaks can be caused by collisions with tiny meteorites or orbiting space debris. The noise of pressurized air escaping a spacecraft shoots into the vacuum of space. Besides, spacecraft walls are covered with gear, instruments, gadgets and tools. So it once took astronauts two weeks to find a leak in the International Space Station. Dale Chimenti, an Iowa State professor of aerospace engineering, and Ronald Roberts, a scientist at the Center for Nondestructive Evaluation, are working on measurement and computing technology that can detect and pinpoint leaks in about 30 seconds. Prof. Chimenti said the system detects the minute vibrations produced by the skin of a spacecraft when pressurized air escapes in a turbulent rush. Taking measure- ments from two locations allows researchers to use triangulation to pinpoint the leak. • Carbon nanotubes The tubes are strong, light and potentially useful for electronic and mechanical applications. But they’re tiny, just a few atoms across. They’re very smooth, too. So it’s a challenge for researchers to work with them, let alone put them to good use. Vladimir Tsukruk, a professor of materials science and engineering, is working to wrap the tubes with a long-chain polymer. That should help researchers handle and align carbon nanotubes. And that could allow carbon nanotubes to be used as sensors on spacecraft. Such sensors could be used to examine the gases in a spacecraft’s air. He said carbon nanotube sensors would be much smaller and much lighter than existing technologies. • New space materials NASA is designing a new composite material that will be used to construct some of the structures on the next generation of space telescope, the James Webb Space Telescope. The new composite is a polymer reinforced with two types of carbon fiber. David Hsu, a senior scientist at the Center for Nondestructive Evaluation, is using ultrasonic technology to test the composite so re- Virginia’s Engineering Address - www.vaeng.com searchers have a better grasp of its properties. He’s also testing the composite after it was exposed to temperatures down to minus 424 degrees Fahrenheit. He is using ultrasound technology to study micro cracking caused by the thermal tests. • High-tech nature Nanotechnology is pushing technology smaller and smaller. And that makes it harder and harder to produce 3-D materials for nanotechnology applications. How do you make holes, crevices and rims on structures only a few millionths of a meter across? Mufit Akinc, professor and chairman of materials science and engineering, is working with the tiny silica shells created by microscopic, single-celled algae called diatoms. He’s using chemical vapors to turn the silica shells – which come in thousands of shapes – into compounds such as titania and barium titanate. He said the compounds and their fancy shapes have potential for use in micro devices and sensors. Other Iowa State projects for NASA include development of new magnetic sensors for spacecraft, study of new materials for advanced sensors, improvements in X-ray techniques for early detection of cracking in spacecraft and development of computer simulation tools to assist NASA with ultrasonic inspections. Prof. Akinc said the NASA projects provide some interesting work for Iowa State scientists. Yes, he said, “It’s also fun to work on these things.” ## AEMC Instruments Sales & Rentals Power Quality Analyzers • Electric Data Loggers Other Quality Products Available Include Cable Testers • Clamp-on Meters • Data Loggers Current Probes • Ground Resistance Testers Hipot Testers • Megohmmeters • Digital Multimeters Environmental Testers Hanover Technical Sales, Inc.

Findings were detailed in a paper presented recently during the International Mechanical Engineering Congress and Exposition. The conference is sponsored by the American Society of Mechanical Engineers (ASME). The approach represents a potential change in how automotive suspension systems will be designed in the future, said Douglas E. Adams, an associate professor of mechanical engineering who is leading the research. "The way it's done now is that each of the parts making up the suspension are manufactured to be as rugged as possible," Prof. Adams said. "Usually, different suppliers provide the different components, and what they do as good suppliers is optimize the strength and durability of their component. "The problem with this approach is that some of the parts are over-engineered and heavier than they need to be because they are designed to withstand greater forces than they will encounter once they are integrated into the system. This results in a heavy suspension system that doesn't handle very well, and higher fuel and steel consumption than you would like. "A better, more integrated approach that automakers are now pursuing is to test the entire suspension by analyzing parts, not as isolated units but as interconnected components. That way, we will learn more precisely how individual parts interact with each other, and we will be able to design parts that are just as light and rugged as they need to be but not too heavy or rugged." The integrated approach is particularly important for the design of Page 16 The Virginia Engineer suspension systems because one damaged part can cause heavier strain on surrounding parts. If engineers know which parts are most prone to damage, those parts can be Muhammad Haroon, a Purdue mechanical engineering doctoral student, works on sensors installed in a car suspension system at the university's Ray W. Herrick Laboratories. (Purdue News Service photo/ David Umberger) built heavier and other parts can be made lighter, reducing the overall weight and improving the performance of the suspension. A suspension system consists of parts such as bolts, rubber bushings, coil springs, steering mechanisms and tie rods. The method developed at Purdue senses naturally occurring vibration patterns to detect damage to components. Sensors called "triaxial accelerometers" are attached to suspension components and are used to collect data as vibration passes through the components. The data are fed to a computer, where complex software programs interpret the information to analyze each part's performance. Such "fault-identification" methods may not only provide information for designing better suspensions but also might be used for future "structural health monitoring" systems in cars that automatically detect damaged parts and estimate how long they will last. When perfected, such a "systems approach" could provide a competitive edge to companies that make March 2006 suspension parts. The work is funded by ArvinMeritor Inc., which makes suspension components at its plant in Columbus, IN. The research also is supported by the Center for Advanced Manufacturing, located in Purdue's Discovery Park, the university's hub for interdisciplinary research. "We want to develop instrumentation, sensing methods and technologies and also ways to process data that industry can use to conduct durability tests on so-called integrated suspensions," Prof. Adams said. "The company that designs an integrated suspension system that is lighter and lasts longer than the component-wise suspension will have a competitive advantage over other companies." The research paper, written by mechanical engineering doctoral student Muhammad Haroon and Prof. Adams, focuses on bolts connecting the various components in the suspension system of a luxury sedan. In research conducted at the university's Ray W. Herrick Laboratories, the engineers showed that their system was able to detect damaged bolts, precisely determine how a bolt's performance was affected by the damage and how its changing performance affected other parts in the suspension system. "What we've shown in this particular paper is that we can detect very small changes in a part's performance when it is damaged, and we've also been able to quantify the changes, which is really significant," Prof. Adams said. "We quantify the changes by turning data into information using a software algorithm that utilizes an embedded sensitivity model, which we developed. "The reason it's important to quantify the change is that, if we know one part is experiencing a failure mechanism of a certain type and another component is experiencing increasing strain as a result of the damaged part, we can figure out which parts need to be heaviest and which can be lighter." The researchers hope to complete work to develop the method in less than two years, at which time it could be ready for commercial use. ## Virginia’s Engineering Address - www.vaeng.com Testing Of WorldRecord Magnet Completed The National High Magnetic Field Laboratory has ended its year with another achievement of international importance as engineers and technicians recently completed testing of a world-record magnet. With the completion of a new, 35-tesla magnet, the highest-field “resistive” magnet in the world is now located at the Tallahassee facility. The state-of-the-art magnet, which incorporates “Florida-Bitter” technology invented at the laboratory, was designed and built onsite and is immediately available for research. The 35-tesla magnet is an upgrade of an existing 30tesla magnet and surpasses the previous record of 33 tesla, also held by the laboratory. “Tesla” is a measurement of the strength of a magnetic field; 1 tesla is equal to 20,000 times the Earth’s magnetic field. Typical magnetic resonance imaging (MRI) machines in hospitals provide fields in the range of 1 to 3 tesla. Put another way, the increase from 30 to 35 teslas in the new magnet represents a 17-percent jump, or an increase equal to the magnetic force of two MRI machines. “With the advances that magnet lab engineers and technicians have made in magnet technology, it would be easy to become nonchalant about the significance of these world records,” said Gregory S. Boebinger, director of the facility. “But each increase in field represents world-class engineering and a quarter-of-a-million-dollar investment to provide new and unique opportunities for scientific discovery.” Mark D. Bird, project leader on the 35-tesla upgrade, said that as engineers learn more about existing materials and as new materials become available, the lab is able to upgrade its existing magnets. “We continuously strive to improve the performance of our magnets both by pushing the fields higher and by increasing the quality of the fields,” said Mr. Bird. “Our next new magnet will focus not just on high field, but uniform field as well.” And higher and more stable fields are exactly what the laboratory’s users, who come from all corners of the world, demand. The magnet laboratory is funded by the state of Florida and the National Science Foundation (NSF) to provide the international research community with the highest magnetic fields possible to conduct research in all areas of science. Use of the magnets is free as long as researchers agree to share the results of their work. The majority of the magnets and instrumentation used at the magnet laboratory are developed by the laboratory staff and operated by in-house researchers who collaborate with the hundreds of scientists who visit the facility each year. The 35-tesla magnet, which Virginia’s Engineering Address - www.vaeng.com has a 32 mm, or 1.25-inch, experimental space, is intended to be used primarily for physics and materials science research. Magnetism is a critical component of many scientific discoveries in addition to a surprising number of modern technologies, including computer memory and disk drives. High-field magnets now occupy a place beside lasers and microscopes as essential research tools for probing the mysteries of nature. Long used by the physics community to understand the fundamental nature of matter and electronic structures, magnetic fields now are used by biologists, chemists and even pharmacists to better understand complex molecules and tissues, and in fact are responsible for the development of the MRI technology that has changed the face of modern medicine. Funded by the National Science Foundation and the State of Florida, The National High Magnetic Field Laboratory is operated by a consortium consisting of Florida State University, the University of Florida and Los Alamos National Laboratory. The Tallahassee facility houses both resistive — so-called “powered” — magnets that use both electricity and cooled water to operate and superconducting magnets that, once brought to full field, require little or no electrical power to run. In July 2005, the lab commissioned a world-record, 900megahertz, wide-bore nuclear magnetic resonance magnet, which is expected to yield important discoveries in the fields of chemical and biomedical research. ## C & W CONTROL CO.

Over the course of the next 300 years, growth in all directions within the Commonwealth would incorporate the use of horses, wagons, boats, and trains in the movement of people and goods. As the early wilderness areas were transformed into homesteads, and shortly, towns and cities began to dot the landscape, Virginia’s leaders began to realize that a more comprehensive, better planned and coordinated approach to transportation was needed. The arrival of the 20th century brought with it the age of the automobile. And while Virginians were quick to embrace the new technology, the infrastructure to accommodate these new horseless carriages was woefully inadequate. By 1906, the General Assembly had decided to do something about the new momentum toward motoring and on March 6, established the first state Highway Commission. The first highway project began in August 1906 in Washington County between Meadow View and Graham’s Bridge. The 20-foot-wide road was to have macadam 12-14 feet in width and generally six inches in depth. Other milestones during those early years of organization and operation include: — projects begun in December 1906 to facilitate the 1907 Jamestown Exposition, including a road connecting Williamsburg with Jamestown Island; — issuance of the first vehicle license in 1906 (by 1910 Virginians had registered 2,470 vehicles); — passage of the State Convict Road Force Act in 1906; — passage of the first appropriaPage 18 The Virginia Engineer tion for road construction in 1908, for $250,000 annually “out of any money in the state treasury not otherwise appropriated;” — in 1916, passage of the Federal Road Act, forcing states to organize highway departments which would plan a state system of highways coordinated with a national system; — In 1918, Virginia passed the State Highway Act, establishing a state highway system of 4,002 miles, which would be the state’s responsibility to build and maintain; — in 1927, the Department of Highways was established as a state agency; — in 1956, Congress called for the construction of a 42,500-mile interstate highway system of which the distance planned for Virginia equated in length to a superhighway from Richmond to Des Moines, Iowa; — in 1967, Virginia became the third state in the nation to enter into an agreement with the Federal Highway Administration on standards for control of outdoor advertising signs along interstate and federalaid primary highways; and — in 1974, the agency was renamed the Department of Highways and Transportation. Throughout its first 75 years, the newly named Department of Highways and Transportation had weathered many challenges. The 1980s brought inflationary construction costs compounded by diminishing construction revenues. Maintenance expenses for Virginia’s highway infrastructure also spiraled upward, and highway-user tax receipts failed to meet expectations. Early in the decade, the department was forced to lay off approximately 120 employees because of funding shortfalls. Lawmakers tried to deal with declining revenues for road construction by increasing gasoline taxes and user fees. In the mid-1980s, March 2006 Gov. Gerald Baliles appointed the Commission on Transportation in the 21st century (COT 21). The commission’s recommendations for new funding sources resulted in a half-cent being added to the sales tax, with proceeds dedicated to transportation funding. Other user fees also were increased. These initiatives meant a doubling, and in some areas, tripling, of the highway construction program. The department took multiple measures to meet the challenge, cutting the time it took to complete highway projects by 20 percent, and doing it with fewer people per dollars spent. Other innovations followed. Special tax districts were approved to allow localities to raise funds for accelerated road construction. Private companies were given the opportunity to build and operate forprofit toll roads; the Dulles Greenway resulted. One of the events indicating a more multimodal approach to transportation planning was another change of the department’s name. No longer would the department’s name mention highways, but rather it would reflect a much broader approach to keeping Virginians moving. The new name, legislated in 1986, was the Virginia Department of Transportation. The age of VDOT had begun. In late 1991, 976 employees took advantage of VDOT’s “early retirement” program, leaving the agency to streamline operations and do more with less. In 1995, another 1,227 employees chose to separate from state service under the Workforce Transition Act. The act was designed to reduce the size and scope of state government, encouraging agencies to find more efficient ways to do business. A strong focus on operating Virginia’s highways more efficiently directed VDOT throughout the 1990s.

By August of that year, VDOT employees had developed the Web-based Dashboard – an early warning system for project managers to see in an instant which jobs are at risk of falling behind schedule or going over budget. Using the red yellow and green lights of a traffic signal, the Dashboard also measures VDOT’s success by showing which projects are on track, and it serves as a tool to help managers do the best job possible.

In September 2002, VDOT opened its first Public-Private Transportation Act (PPTA) project – the Pocahontas Parkway near Richmond. Route 288 also in the Richmond area followed in 2004. Four others are due for completion by spring 2007. As VDOT reaches its 100th birthday, major construction projects are nearing completion including the Hampton Road area’s Coliseum Central project, due to finish in August 2006; the Northern Virginia area’s Springfield Interchange Improvement Project by late 2007, and the new Virginia/Maryland/D.C. Woodrow Wilson Bridge Project due to finish on time and on budget in 2011. In the years to come, it is clear that transportation funding will remain a major issue in keeping up with demand, and in keeping Virginia moving toward the next 100 years of transportation excellence. ## (Editor’s Note: The information and photographs presented in this article were made available through the Virginia Department of Transportation.

But the barren site of a future intersection might be an opportunity to consider another option for traffic management, the modern roundabout. These have been built by the tens of thousands worldwide. The main benefits have been to improve traffic flow and reduce injury crashes by as much as 75 percent compared with intersections controlled by stop lights or signs. But only about 1,000 roundabouts have been built in the United States. “Transportation engineers, like everybody else, generally go with what they’re used to, and what they’re used to on U.S. roads is constructing standard four-way intersections equipped with stop signs or signal lights. Doing this means missing the benefits of roundabouts, so we’d like to encourage officials to consider roundabouts earlier and more often in the roadway planning process,” explains Richard Retting, the Institute’s senior transportation engineer and author of two new studies that suggest how to overcome traditional impediments to building roundabouts. One impediment is logistical: It can be costly and disruptive to tear up an existing intersection and replace it with a roundabout. The easiest way around this is to construct the roundabout to begin with, before an intersection with a traffic light or stop sign is installed. Another roundabout opportunity is when an intersection with a signal light is scheduled for major modification. Insurance Institute for Highway Safety researchers studied 10 intersections where roundabouts could have been constructed but weren’t. Instead local officials either outfitted the new intersections with traffic signals or retained the signal lights at intersections that were undergoing major modifications. The researchers measured traffic volumes, monitored the number of crashes that occurred, and estimated vehicle delays and fuel consumption at the intersections with the signals. Results were compared with estimates of what could have been expected with roundabouts instead. A key finding is that vehicle delays at the 10 intersections would have been reduced by 62-74 percent, saving 325,000 hours of motorists’ time annually. Fuel consumption would have gone down by about 235,000 gallons per year, and there would have been commensurate reductions in vehicle emissions. The safety benefits also are considerable.

Page 20 The Virginia Engineer March 2006 cates that roundabouts reduce crashes by 37 percent overall — injury crashes by 75 percent — compared with intersections that have signals. Applying these risk reductions to 5 of the 10 intersections for which crash data were available, researchers estimated there would have been 62 fewer crashes over 5 years. There would have been 41 fewer injury crashes. “If only 10 percent of the 250,000 intersections with signals in the United States were modified as roundabouts, the national safety and fuel saving benefits would be enormous,” Mr. Retting points out, “and you can reap these benefits without as many logistical challenges if you ‘think roundabout’ from the very beginning of a roadway project, for example when new housing or shopping developments create the need for roadway construction. Then it can be less expensive to construct a roundabout than to install traffic lights. Plus the developers may be required to fund the roundabout construction as a condition of zoning approval. Initial opinion may be an impediment: Study after study, including the Institute’s most recent one in northern Virginia, clearly indicates the benefits of roundabouts in reducing both crashes and traffic congestion. Yet roundabouts frequently run into opposition, especially before they’re constructed. Institute researchers conducted telephone surveys of residents in three communities in New Hampshire, New York, and Washington State where intersections with stop signs or traffic lights were being replaced with roundabouts in 2004. The opinion surveys were conducted before the roundabouts were built and twice more, about six weeks after construction and then about a year later. Fifty-four percent of the survey participants initially said they opposed roundabouts. One-third said they were strongly opposed. These proportions changed considerably right after construction, as motorists began getting used to the roundabouts. Then only 36 percent said they were opposed, and the Virginia’s Engineering Address - www.vaeng.com proportion in favor increased from 36 to 50 percent. “It might not sound like much of a victory to find out that half of the respondents expressed their approval for roundabouts. But the first follow-up surveys were conducted soon after motorists began navigating this new form of traffic control. Roundabouts weren’t yet routine,” Mr. Retting explains. Opinion surveys conducted more recently indicate a growing approval by motorists. More respondents now say they like the roundabouts, while fewer say they disapprove. Previous before-and-after surveys have revealed similar turnarounds in public opinion. This is because many motorists find out, through their own experience, that vehicles generally flow more smoothly through roundabouts than through intersections controlled by traffic signals. Delays are reduced. In many cases there’s no need to stop at a roundabout, just slow down. Message for transportation officials: “What these two studies teach us is simple. Just build them. Go ahead and construct a roundabout where it’s appropriate, and do it, if possible, when a roadway is first engineered,” Mr. Retting advises. Especially in suburban areas where population growth and housing development are escalating and new roads are planned, officials would do well to consider roundabouts. “Don’t let initial opposition get in the way,” Mr. Retting adds. “Many U.S. motorists aren’t familiar with roundabouts yet, so they’re wary of them. But once the roundabouts are built, the traffic flow and safety benefits turn people around, even people who weren’t enthusiastic from the get-go.” ## cess that makes hydrogen an affordable energy alternative.” The new membranes, which were developed in the lab of Chemical Engineering Professor Benny Freeman in Austin and A team of engineers and scien- hydrogen as alternative motor fuel tested there and at RTI, take advantists at The University of Texas at has been the cost of purifying it,” tage of plasticization by gases such Austin and RTI International de- said Raghubir Gupta, Ph.D., direc- as carbon dioxide and water vapor to enhance their separaveloped new polymer tion performance.

Directionally emitting radioactive sources, a device for placing needles and seeds, and a super-fast treatment-planning method were developed by University of Wisconsin-Madison (UW-Madison) engineering physics professor Douglass Henderson and medical physics associate professor Bruce Thomadsen. Together, this suite of inventions could mean on-the-spot treatment reoptimization - the holy grail of prostate cancer seed placement. To eradicate diseased tissue, physicians implant up to 100 radioactive seeds in the prostate. Like a tiny grain of rice, each seed is cylindrically shaped and emits radiation in all directions-increasing its likelihood of zapping healthy tissue, too. So, borrowing a concept from nuclear materials handling, Henderson and Thomadsen designed directional seeds-sources with vertical shielding along one side. "I think nobody's done it before because they look at these sources, which are only eight-tenths of a millimeter in outer diameter, and they say there isn't enough space to put shielding," says Prof. Thomadsen. "We found you can compress things and you can do it." As a result, they can implant seeds, particularly at the boundaries between healthy and diseased tissue, that steer radiation where it's needed most. With graduate student Liong Lin, the two developed prototypes and conducted successful radiation simulations. Now they are working with a leading brachytherapy products company to develop experimental prototypes. To keep the seeds from rotating once they're implanted, the group also hopes to modify their design to incorporate a wedge-shaped anchor along one vertical side. "It only has to hold the source about three days, and after that time, tissues start sticking to it," says Prof. Thomadsen. Radioactive "seeds", just a few millimeters in diameter, deliver cancer-killing radiation when physicians implant them strategically within diseased tissue. Photo courtesy of Bruce Fritz/ University of Wisconsin-Madison 2005. Implanting the seeds accurately is no small feat. With a hole-studded grid mounted over the patient as a guide, physicians use a hollow needle to insert the seeds manually. They rely on real-time ultrasound images of the prostate to ensure proper seed location and depth. But both the confines of the grid and the ultrasound itself limit the process, meaning that the radioactive seeds may not make it to the correct locations, says Prof. Thomadsen. So he and his graduate students abandoned the grid and built a robot that could deliver seeds more precisely than a physician could by hand. "There's an additional impetus that came along when we started working on the directional sources," says Prof. Thomadsen. "In order to get sources in the patient in the right orientation, it would be very hard for a physician to get the angles precisely." Graduate student Michael Meltsner built a prototype robot and has perfected it by programming it to implant seeds into oranges. "It's a Virginia’s Engineering Address - www.vaeng.com March 2006 really basic prototype, and he's at the point where we have to test to make sure that, in the simple form we have, it's going to perform exactly how we want," says Prof. Thomadsen. By next year, when the system is complete, it will provide countless angles for inserting seeds and will enable physicians to properly orient seeds that contain shielding. To plan the seed placement for maximum effectiveness, physicians currently map an ultrasound view of the prostate on a 3-D grid, use optimization software to calculate several sets of possible seed locations, and determine which configuration will work best. But current optimization methods are iterative methods-that is, they calculate a solution, make a change, calculate a new solution, make a change, and so on. Inspired by a reactor physics technique called adjoint, or "backward" transport, Henderson, Thomadsen and their graduate students developed a method that could reduce the time of this treatment-planning step from as long as 40 minutes to just a few seconds. "The adjoint function plays a big role in the selection of the seed position," says Prof. Henderson. Ultimately, these advances could represent a major leap in precise prostate cancer treatment, says Prof. Thomadsen. "A plan would tell you where to put the seeds," he says. "And each time you put in a seed, it would recalculate where to put the next seed based on where you actually put the first one." For patients, he says, that level of interactivity means less hassle and more peace of mind. "The patient wouldn't have to come in days early for a pre-scan," he says. "They could just come in for the procedure. Everything could happen right then, in live time." Funding for the projects came from the Department of Energy Nuclear Engineering Education Research program, the UW-Madison Graduate School, and the Wisconsin Alumni Research Foundation (WARF). Thomadsen, Henderson and colleagues are patenting the innovations through WARF. ## The Virginia Engineer Page 23 Four Steps To Managing Anyone Motivation and Communication to Get the Job Done by Mimi Donaldson Managing means getting results through people. We do this in many different settings from workplace to household. If you are alive, you have already been a manager. You’ve managed delivery people, repair people, pets, children, in-laws, spouses and more. One myth is that you need to throw money at people to motivate hard work and loyalty. Not entirely true. Management has less to do with charisma than with consistency. Managers depend on effective interpersonal communication skills to get things done. praise along the way. Set the climate. Be sure you’re in a place conducive to concentration at a time when the person can concentrate. Listen to your Step 1: Tell the person clearly what you except them to do. Often a great deal easier said than done. In management training environments, this is called “delegation.” My definition of “delegate” is to empower and motivate a person to accomplish results for which you are ultimately responsible. Delegation includes these guidelines: choose a person capable of doing the job; explain the result you want; give the authority to get it done; monitor the activity; give recognition or Page 24 The Virginia Engineer Cite resources available: Point out where there are other references, if any, on the task. Resources include people who have done the task or parts of it before. Invite questions. Even if it feels as if you don’t have time to do this, it’s worth it. Better to spend the time up front than be unhappily surprised later. Invite questions with openended prompting such as, “What questions do you have?” not “You don’t have any questions, do you?” Empower And Motivate Many of you are called “boss.” To avoid “boss” becoming another fourletter word, follow these four steps: printed in an instruction or procedures manual. You still need to go over these steps, however briefly, with the capable person to assure yourself of the person’s understanding. If the steps are not already written out, have the person take notes as you speak. This increases understanding. Get the person to summarize what they will do to get the job done.

A 300-horsepower fan pulls air through the tunnel. The unit is located outside the building on its own concrete pad and foundation, which ensures its noise and vibration don’t contaminate experiments. The fan is capable of moving air at speeds of up to 170 mph, the typical speed of most commercial jets as they approach an airport for landing, Prof. Cattafesta said. The soundproof room, built by Eckel Industries, was completed in 2002. But UF faculty including Mark Sheplak and Bruce Carroll and graduate and undergraduate students pitched in to design and build the tunnel. Otherwise, Prof. Cattafesta said, it would have been prohibitively expensive. NASA Langley provided the bulk of the funding for the project. Mechanical and aerospace engineering doctoral students Jose Mathew and Chris Bahr said the toughest challenge was the crafting of 60 airfoils that turn the air flow 90 degrees as it leaves the building. The team needed to make that turn to fit the tunnel into the available space, and the fiberglass and rubberfilled vanes make the process as streamlined and quiet as possible, they said. Prof. Cattafesta said engineers have long designed airplanes to be safe, reliable, fuel-efficient comfortable for their occupants. Traditionally, he said, “noise is generally not something you worry about until you hear it.” But thanks to better composite materials and sophisticated computer design tools, that’s changing, he said, and the UF tunnel dovetails with that trend. “It’s clear that by re-engineering things better and better we have an opportunity to reduce the noise,” he said. “We’re really putting ourselves in a position where we can experimentally look at these questions.” Engineers at Purdue University hope their wind tunnel answers questions of a different kind. They have developed a wind tunnel that is the only one of its kind in the world capable of running quietly at "hypersonic" speeds, helping researchers to design advanced aircraft and missiles. No other wind tunnel runs this quietly while conducting experiments in airstreams traveling at Mach 6 - six times the speed of sound, said Steven Schneider, an aerospace engineer and professor in Purdue's School of Aeronautics and Astronautics. Researchers will use the $1 million wind tunnel to help design advanced aircraft that travel at hypersonic speeds, or faster than Mach 5, which is about 4,000 miles per hour at sea level. Purdue engineers presented a paper about the wind tunnel during a recent American Institute of Aeronautics and Astronautics' Aerospace Sciences Meeting and Exhibit. The paper was written by Schneider and graduate research assistants Matthew P. Borg and Thomas J. Juliano. A team of Purdue engineers led by Prof. Schneider finished assembling the wind tunnel in 2001. "After four years of debugging, recent tests have shown that it does, indeed, run quietly at Mach 6," Prof. Schneider said. "The wind tunnel airflow has about one-tenth to onethirtieth of the noise in other highspeed wind tunnels." The quiet operation is critical for recreating the smooth, or laminar, flow of air over the surfaces of aircraft, spacecraft or missiles re-entering the Earth's atmosphere. Data from tests with models studied in the wind tunnel will lead to a better understanding of when and how the air flowing over a surface changes from smooth to turbulent. Engineers must better understand this transition from smooth to turbulent flow if they are to design improved aircraft and missiles. One aim is to design aircraft that heat up less from atmospheric friction as they re-enter the atmosphere. "Laminar airflows can have eight times less heating than turbulent ones," Prof. Schneider said. Designs that heat up less would require less shielding, enabling engineers to build lighter-weight, lower-cost vehicles. "Designers are considering a new re-entry vehicle with a metal skin," Prof. Schneider said. "This would eliminate the tile system used on the space shuttle, which is expensive to maintain." Another major application will be to design a generation of aircraft that will use "scramjets" enabling travel at more than 7,000 mph, allowing them to leave the atmosphere and fly halfway around the world in a few hours. A future fleet of space planes using scramjets might be far less expensive to operate than the current space shuttles, making it more affordable to haul payloads into orbit. Unlike rockets, which must carry their own supply of liquid oxygen to combust fuel, scramjets would scoop oxygen out of the atmosphere. For scramjets to work properly, however, a steady, smooth flowing supply of air must be moving continuously at hypersonic speeds into the engine's combustion chamber.

The National March 2006 Virginia’s Engineering Address - www.vaeng.com A JOHNS HOPKINS University archaeological expedition in Luxor, Egypt, has unearthed a lifesized statue, dating back nearly 3,400 years, of one of the queens of the powerful king Amenhotep III. The statue, which dates to between 1391 and 1352 B.C.E., was uncovered recently by the expedition’s director, Betsy Bryan, Johns Hopkins professor of Egyptian art and archaeology. Bryan and a graduate student, Fatma Talaat Ismail, were clearing a portion of the platform of the temple of the goddess Mut in Luxor, an area dating to about 700 B.C.E. The statue, which was lying face down in the ground, appeared to have been used as building rubble, Bryan said. “The statue, however, when it was removed, revealed itself as a queen of Amenhotep III, whose name appears repeatedly on the statue’s crown,” Bryan said. She said she theorizes that perhaps this statue is of the great Queen Tiy, wife of Amenhotep III and mother of the so-called heretic king Akhenaten, who came to the throne as Amenhotep IV but later changed his name because of his rejection of the god Amen in favor of the sun disk Aten. “Tiy was so powerful that, as a widow, she was the recipient of foreign diplomatic letters sent to her from the king of Babylonia in hopes that she would intercede with her son on behalf of the foreign interests,” Bryan said. “Some indications, such as her own portraits in art, suggest that Tiy may have ruled briefly after her husband’s death, but this is uncertain.” Photo courtesy of Jay VanRensselaer/JHU.

However, a new study by a team of University of Virginia (UVA) researchers suggests stem cells act as construction supervisors, directing the work of other cells, rather than doing the heavy lifting themselves. “Our findings indicate a new understanding of the role played by adult stem cells,” said Thomas Skalak, chairman of the Department of Biomedical Engineering, who along with his colleague Gary Owens, professor of molecular physiology, is leading the research team. “It’s a shift from a building role to a signaling role, orchestrating the repair and growth of damaged tissue.” The research team’s findings suggest a new tack in the search for Virginia’s Engineering Address - www.vaeng.com March 2006 DIRECTORY OF ENGINEERING SERVICES Engineers • Surveyors Lab Analysts • Plant Operators water & wastewater systems • sanitary engineering site development • subdivisions • shopping centers topographic • boundary surveys • lab analysts 212 E.

Blockbuster drugs have been single molecules that target a single process, but the adult stem cells we studied appear to coordinate several processes in repair and growth, which single molecules have not been able to do.” The research team’s results are published in a recent issue of the peer-reviewed journal Circulation Research.

However, in smaller, lowerpressure distribution mains, ‘pigs’ are inappropriate and so robotic devices are currently under development for the inspection and repair of these pipelines. Secure, reliable communication is needed to support these robotic devices.” In a Department of Energyfunded study, a team of UMR faculty found that the 1.2 million miles of natural gas distribution and transmission pipelines that crisscross the March 2006 Henkels & McCoy, Inc.

Known as 802.11 or Wi-Fi, wireless networks use radio links instead of cables to communicate between computers. Initial tests were conducted on a small pipeline loop at UMR, with subsequent field testing on a much longer pipeline loop at the Battelle Pipeline Simulation Facility near Columbus, OH. “We found that we could communicate over a little less than a mile with a 24-inch pipe,” Dr. Erickson says. “It did well, even around Ushaped curves.” The wireless network could support un-tethered inspection technologies, like the RoboScan™ and Explorer™ robots, for the evaluation of pipeline conditions. The pipeline can transmit a radio signal and deliver gas at the same time, Dr. Erickson says. “The robots would try to detect a problem within a pipeline before it became a problem,” he adds. “There could be hundreds of these miniature robots that reside in the nation’s pipelines, roaming and looking for deterioration.” The robots can currently send back visuals from inside the pipeline as well as conduct electronic scans of the pipe. Eventually, the robots would not only inspect but also repair pipelines, Dr. Erickson says. “This is even more important in the northeast, where it’s denser,” Dr. Erickson says. “Repairing pipelines there can be difficult because the pipes are often under buildings. The robots may one day be able to fix the problem without having to dig down to the pipeline.” Ben Franklin Web Site Offered For the 300th anniversary of Benjamin Franklin's birth, a new Web portal (http://ben.clusty.com) is offering a comprehensive, searchable resource of the iconic statesman's writings and quotations, along with a targeted search engine and tools for teachers.

The group will base its studies in the Center for Advanced Nuclear Fuel-Cycles (CANF), a new initiative housed at Argonne. Co-directors at Argonne and the University of Wisconsin-Madison will lead the center. The project is also intended to provide valuable educational experience for the next generation of scientists and engineers. Nuclear fuel used in current reactors has enormous available energy. As the fuel is used to produce electricity, only a fraction of this available energy is actually consumed, generating a small quantity of high-level radioactive waste within the solid fuel. Currently, most spent nuclear fuel is stored temporarily in secure, specially designed pools at commercial reactors around the country, or in leak-tight steel casks housed in March 2006 GET NOTICED!!

When space is full, the fuel could end up at a commercial temporarystorage facility in Utah, or perhaps at the proposed Yucca Mountain high-level waste repository. But these storage options are short-term approaches to dealing with the back-end of the nuclear fuel cycle, says Michael Corradini, a UWMadison professor of engineering physics and the center's co-director. "We hope to develop a 'sustainable' fuel cycle-that is, an efficient, costeffective way to reuse current spent nuclear fuel and minimize its byproducts," he says. "Advanced nuclear fuel cycles can be recycled as a source of available energy as demand for uranium increases." A number of countries, including Japan and France, currently have programs to reprocess their spent nuclear fuel using a process known as PUREX (plutonium and uranium recovery by extraction). The CANF team will seek to improve upon these separation and recycling processes. "The major difference is that we are looking for ways to successfully extract specific radioactive species for separate uses and separate disposal," says Prof. Corradini.
