How do I know how much money it
will take to keep my network at an
acceptable level of service?
M & R Plans
Run M&R plans to illustrate current and future
pavement conditions at various levels of
spending.
What If Scenarios
What if I want to maintain my current
condition?
What if I want to achieve a better overall
condition?
How many years will it take to get there?
What if I spend more money now?
What if I spend more later?
What roads should I spend the money on?
$1 Million/Year Budget
$3 Million/Year Budget
Once I know how much money our agency
needs, will the “powers that be” agree?
