IMPROVING PREDICTION OF
HOT MIX ASPHALT STABILITY
Battered by weather and increasing traffic loads, asphalt concrete pavements throughout
the nation are wearing out much sooner than expected. According to the American
Association of State Highway and Transportation Officials (AASHTO), the result is
rough pavements, higher maintenance and rehabilitation expenses, and more temporary
work zones that slow traffic and endanger workers and motorists.
Developed under the Strategic Highway Research Program, Superpave technology is
aimed at improving the performance, durability, safety and efficiency of the nation's
highway system. Superpave--an acronym for SUperior PERformingAsphalt
PAVEment--is a system of performance-related hot asphalt (HMA) mix design
specifications.
