As a result of its participation in the long-term pavement performance (LTPP) program, the Kansas Department of Transportation (DOT) has confirmed the importance of preventive maintenance, improved its preventive maintenance techniques, and expanded its range of preventive maintenance treatments. The result-a highly effective and economical strategy for keeping asphalt concrete pavements in top condition.
Having trouble getting up to speed with the Superpave system? Don't panic-the Superpave Lead States team has assembled a list of engineers and technicians who are ready and able to provide technical support and assistance with everything from Superpave binder testing to pavement construction.
Representatives of highway agencies and industry recently pledged to continue their support for the ongoing long-term pavement performance (LTPP) program and to seek additional project sites for the program's Specific Pavement Studies (SPS) experiments. The pledge came at a meeting initiated by the American Association of State Highway and Transportation Officials (AASHTO) Task Force on SHRP Implementation.
A number of National Cooperative Highway Research Program (NCHRP) projects are investigating further enhancements to the Superpave system.
Reclaimed asphalt pavement (RAP) is an integral ingredient in most asphalt pavement construction and rehabilitation projects. Not only is RAP good for the environment, because it recycles materials rather than adding them to landfills, but it is also more economical.
