• Abstract:
  This report summarizes research conducted at Iowa State University on behalf of the Iowa ; Department of Transportation, focusing on the volumetric state of hot-mix asphalt (HMA) ; mixtures as they transition from stable to unstable configurations. This has traditionally been ; addressed during mix design by meeting a minimum voids in the mineral aggregate (VMA) ; requirement, based solely upon the nominal maximum aggregate size without regard to other ; significant aggregate-related properties. The goal was to expand the current specification to ; include additional aggregate properties, e.g., fineness modulus, percent crushed fine and coarse ; aggregate, and their interactions. The work was accomplished in three phases: a literature review, ; extensive laboratory testing, and statistical analysis of test results.
