Analysis of Asphalt Mixtures Using Alternative Aggregate in SMA and Superpave

The objective of this study is to identify and compare alternatives to Traprock through testing and laboratory evaluation along with conducting a literature review of current practices of neighboring DOT’s. MoDOT is interested in finding other locally available, durable crushed aggregates for use in SMA and higher level Superpave mixes that could handle interstate traffic and are less expensive than Traprock.
