Implementation of a Laboratory Conditioning and Testing Protocol to Evaluate Moisture Susceptibility of Asphalt Mixtures

This research would have four major objectives: (1) determine the most effective moisture susceptibility test that can identify the impact of chemical anti-stripping agents, warm-mix additives, and lime on stripping resistance; (2) develop a detailed test procedure for the selected experiment; (3) determine test parameter thresholds for Oregon mixes to identify asphalt mixtures with acceptable stripping resistance; and (4) using the developed test protocol, determine the impact of different anti-stripping agents and warm-mix additives on moisture susceptibility of Oregon asphalt mixtures.
