Abstract:

As state transportation departments continuously maintain and repair worn roadway surfaces, research engineers in nearly every state are racing to find ways to increase pavement life. Three states in particular� Wisconsin, Minnesota, and Georgia�are investigating very different, but important pavement performance criteria that could help other states. Researchers in Wisconsin are testing less costly, longer-lasting pavement construction methods. The Minnesota DOT has been investigating why older pavements are wearing out before their expected design life. In the southeast, pavement engineers at the Georgia DOT are monitoring the performance of a microsurfacing job near Atlanta.
