Type of PavementMaintenance Preventive (Proactive)
Arrest light deterioration
Retard progressive failures
Reduce need for corrective maintenance
“Right” treatment at the “right” time!
Corrective (Reactive)
After deficiency occurs
More expensive

When Do We Have to Fix Our Pavements? Pavement Preservation
preserves good condition pavement
Corrective maintenance When the pavement loses load carrying ability
(excessive deflection)
Waterproofing (cracks)
Surface slope (rutting) Surface roughness (too slick)
Ride quality (bumps)

Road Classifications Importance in
providing connectivityand the functions they
provide. The basic principal is
that roads serve twodistinct functions:
Mobility (the movementof goods and people)and
Access to land

Mobility Build, operate and
maintain atransportation system
that will Reduce traffic
congestion and
Improve travel
reliability (Volume toCapacity ratio)

Mobility Level of Service (LOS)
Improvement
LOS serves as a
measure of a road’sperformance/congestionlevel that utilizes agrading scale
A LOS of “A” representsno congestion and LOS“F” represents severe
congestion

Local Inputs The value of local input from a variety of
stakeholders is significant enough to warrantadditional points for projects
Input will be broken down into three distinctsources: Local Planning Agency input up to 4 points
(MPO’s & RPO’s)
Mayors & County Commissioners up to 3 points(local elected officials)
Citizen and Legislative input up to 3 points
