THE INFLUENCE OF AGGREGATE AND BINDER TYPE ON THE FUNDAMENTAL ENGINEERING PROPERTIES OF STONE MASTIC ASPHALT AND COARSE MATRIX HIGH BINDER MIXTURES
In the paper, a laboratory study was initiated to evaluate the performance of stone mastic asphalt, SMA, and coarse matrix high binder, CMHB, using locally available materials, as compared to conventional Louisiana DOTD type 8F wearing course. Three mixture types were examined: SMA, CMHB, and conventional Type 8 WC mixture (serving as the control mix). In order to evaluate the effect of aggregate type on SMA performance, three types (limestone, sandstone, and novaculite) were utilized for the SMA mixtures; the other mixtures incorporated limestone aggregates. Fundamental engineering tests such as indirect tensile strength and strain, resilient modulus, creep compliance, and fatigue life were used to evaluate the performance of these mixes. In general, SMA mixes exhibited better performance than CMHB mixes. SMA mixes containing polymer modified asphalt and sandstone or novaculite aggregate provided lower axial creep slope than similar mixes with limestone aggregates. Conventional AC-30 and chemically modified binder exhibited lower asphalt draindown than polymer modified asphalt. For the covering abstract of the proceedings, see IRRD 490713.
