Background
 Introduction
 Objectives
 Methodology
 Engineering Properties
 GIS Imagery - ASIS Map
 Recommendations & Conclusion



Aggregate is an integral part of infrastructure
development all over the globe.
Few fundamental engineering properties are
being studied at
Construction Materials Research
Group (CMRG) at NED University



To develop a materials characterization
relational database
Location of quarries and crushers:
characteristics and nearest availability
Development of aggregate source
information system - ASIS




To acquire Information about the Quarries and
Crushers.
To compile the data of engineering properties of
Aggregates.
To prepare a Web-GIS based map depicting the
information of aggregate availability and their
significant properties.
To facilitate the construction industry in terms of,
quality, demand, location and transportation of
materials.
To share the knowledge in academics and industry
regarding the selection of aggregate on the basis of
engineering performance and location

Summary
Sample Collection
•Identification of Quarries and Crushers
•Collection of inherent and crushed rock samples
•Locating the position of quarry and crushers
Aggregate Testing
•Execution of Tests for Coarse and Fine Aggregates
•Evaluation of engineering properties
•Petrographic Studies
Development of
GIS Imagery
•Plotting the Location of Quarries and Crusher
•Uploading the aggregate properties

User friendly web based aggregate database
www.cmrg.neduet.edu.pk


Spatial information of aggregate
The web based ASIS has the capability to be
modified





ASIS should be periodic and extensive
Narrow down the distances of selection of
quarries and crushers
More standard tests are to be included to make
it reliant
Should be publically free and available
ASIS map of other part of country
Serve as land marks for other products and
services
