AN INDUSTRY DISCUSSION ON SUPERPAVE IMPLEMENTATION

A major element of the Strategic Highway Research Program (SHRP) was research on asphalt. Extensive research was done on both asphalt cement binder tests and specifications as well as tests and specifications on Hot Mix Asphalt (HMA) materials. The research activities generated a wealth of new technical information regarding HMA and binders which far exceeds the money spent in the SHRP. The products of the SHRP work were combined into an overall asphalt/aggregate mixture design and analysis system called Superpave. The purpose of this paper is to offer an industry perspective for the appropriate implementation of the Superpave mix design system.
