AASHTO Innovative Highway Technologies Innovative Pavement Maintenance Materials

Cracks, potholes, joint seals, partial-depth spalls, and other common problems that affect asphalt and portland cement concrete pavements can be more easily and effectively repaired using innovative materials and techniques evaluated under the Strategic Highway Research Program. These techniques include the spray injection method for pothole patching; use of the Georgia digital faultmeter, which measures the differences in elevation across a joint; and use of the Iowa vacuum tester, which detects leaks in joint seals.

From 1995-2000, the Lead States Team helped States and local governments implement these innovative methods and materials. Its activities included sponsoring field demonstrations and developing a guide manual to help States plan and set up their own hands-on demonstrations.

In September 2000, the team tranferred its responsibilities to the Subcommittee on Maintenance of the American Association of State Highway and Transportation Officials (AASHTO), specifically to the Pavement Task Force. The Team prepared a Transition Plan detailing the results of their work and recommendations for the future.
