Laboratory Evaluation of Effects of Soaked Duration on Moisture Susceptibility of Warm Mix Asphalt Mix

Moisture damage in flexible pavements might cause stripping in the asphalt pavement and ultimately lead to premature failure. In addition, rising energy prices, global warming, and more stringent environmental regulations have resulted in an interest in warm mix asphalt (WMA) technologies as a mean to decrease the energy consumption and emissions associated with conventional hot mix asphalt production. In this study, the objective was to conduct a laboratory investigation of long-term influence of anti-stripping additives on moisture damage in WMA mixtures. The test results indicated that the aggregate source did not show a remarkable effect on moisture susceptibility of mixture in this study. The addition of anti-stripping additives increased the ITS, TSR, and flow values; however, the differences were not statistically significant compared to the control mixtures. Mixtures containing Asphamin® did not perform as well as others. In addition, an increase of condition duration decreases the anti-stripping resistance regardless of mixture type.
