VOLUMETRIC AND MECHANICAL PERFORMANCE PROPERTIES OF SUPERPAVE MIXTURES

摘要

This investigation was carried out to study the volumetric and mechanical performance properties of the Superpave mixtures SP-1 and SP-2 and a typical Taiwan mixture (TTM). Both the Marshall and the Superpave ix design procedures were used to produce these mixtures, and the Superpave gyratory compactor Was used for realistically compacting specimens to densities achieved under actual pavement conditions. These Three mixtures were tested using the Superpave shear tester for conducting a simple shear test at constant height, Frequency sweep test at constant height, and repeated shear test at constant height.
