AASHTO T 383-21

This method covers the laboratory performance evaluation of asphalt release agents (ARAs). These ARAs are used for coating metal on truck beds, pavers, rollers, slat elevators, and hand tools to prevent asphalt binder or asphalt mixtures from adhering. The ARAs should perform this function without causing degradation (stripping) of the asphalt mixture.

This standard was formerly designated as provisional standard TP 102.
