Stability of conventional bituminous pavements is compromised and rutting rates are accelerated by continually increasing traffic volumes and heavy truck traffic. Some Matrix Asphalt (SMA) was identified during the 1990 European Asphalt Study Tour (EAST) as a possible replacement mix for heavily trafficked pavements. The report documents Illinois' experience with seven SMA projects. To determine what would best suit Illinois, the Illinois Department of Transportation (IDOT) investigated two different types of mixture gradations, three types of aggregates, and three types of modifiers. Findings to date indicate the three types of aggregates and modifiers performed adequately when designed to the coarser mixture gradation. The small SMA gradation type was not as successful. These mixtures generally were tender and flushed.
