NCHRP Report 455 - Recommended Performance-Related Specification for Hot-Mix Asphalt Construction: Results of the WesTrack Project

This test was performed on cylindrical specimens (cores) 150-mm (6-in.) diameter × 50-mm (2-in.) height. Each specimen had cut surfaces on the top and bottom as well as on the vertical face. The RSST-CH was performed at three temperatures—40°C (104°F), 50°C (122°F), and 60°C (140°F)— with the majority of tests being performed at 50°C (122°F). Shear loading was applied in the form of a haversine with a time of loading of 0.1 sec and a time interval between loadings of 0.6 sec. An equation of the form
