Summary:
Transverse cracking associated with asphalt aging and temperature variation is a problem in many asphalt cement
pavements.  The problem is generally dealt with by filling cracks and placing an asphalt pavement overlay on the
cracked surface.  In most cases the cracking will reflect through the overlay, with the reflection time depending on
overlay thickness and pavement conditions.  This reflection of cracking posts a major problem in roadway rehabilitation.
Several products now on the market, when used as interlayers between the old surface and overlay, show promise for
reducing reflective cracking.  Many of these products have been tested, showing both successful applications and
failures.  It is the intent of this program to evaluate and compare four different interlayer systems.  The comparison will
be based on construction application, cost analysis, and post-construction performance.
