Performance Evaluation of Louisiana Superpave Mixtures. TECH SUMMARY December 2008
Currently, more than 93 percent of all the road surfaces in the U.S. are paved with asphalt mixtures. Since the discovery of the petroleum asphalt refi ning process and the growth of the interstate system, asphalt binder usage in the United States has increased from less than 3 million tons in 1920 to more than 30 million tons in 2000. The Marshall and Hveem mix design methods have played important roles in the traditional asphalt mix design; however, both are based on empirical relationships and do not produce fundamental engineering properties of the compacted asphalt mixture that are related to pavement design and performance. The Strategic Highway Research Program (SHRP) was approved by Congress in 1987 to improve the performance and durability of United States roads and make those roads safer for both motorists and highway workers. In 1996, the Superpave asphalt mixture design method was introduced, which incorporates performance based asphalt materials characterization with environmental design conditions to improve performance by controlling rutting, low temperature cracking, and fatigue cracking.
