NCHRP Web-Only Document 186: The Superpave Mix Design System: Anatomy of a Research Program.

摘要

The Strategic Highway Research Program (SHRP, pronounced Sharp) was an unprecedented research effort. It was the largest, most highly focused research effort in the United States since the AASHO Road Test of the late 1950s and went far beyond the Road Test in its breadth and scope. While SHRP was aimed at developing high-payoff products in six focused areas of national need, the Asphalt Research Program was the largest effort in terms of funding and was arguably the most successful. This program eventually led to the development of the Superpave system for the design of asphalt mixtures, which has changed asphalt technology in the U.S. and has had an impact around the world. Superpave has created change in the entire asphalt industry, including asphalt binder suppliers, aggregate suppliers, hot-mix producers, contractors, and specifying agencies at all levels. Superpave introduced new concepts for material testing and selection, new test protocols, new equipment, a new mix design method and new performance testing tools.
