Aggregate Properties and the Performance of Superpave-Designed Hot Mix Asphalt

TRBs National Cooperative Highway Research Program (NCHRP) Report 539: Aggregate Properties and the Performance of Superpave-Designed Hot-Mix Asphalt examines technical literature available since the conclusion of the Strategic Highway Research Program in 1993 on the impact of the aggregate properties specified by the Superpave mix design method on the performance of hot-mix asphalt. The performance of hot-mix asphalt (HMA) is largely determined by the characteristics of its constituents: asphalt binder and aggregate. In developing the Superpave mix design method, the Strategic Highway Research Program (SHRP, 19871993) targeted the properties of asphalt binders and HMA and their effects on pavement performance.
