There is an immediate need for evaluation of the effects of different additives and asphalt binder and aggregate sources on pavements' moistureinduced damage potential. As a response to this need, the present study is proposed to evaluate the moisture-induced damage potential of asphalt mixes used in Region 8. More specifically, effects of reclaimed asphalt pavement (RAP), warm mix asphalt (WMA), anti-stripping agent (ASA), polymer-modified asphalt binders (PMA), and sources of binders and aggregates on moisture-induced damage potential of mixes commonly used by asphalt contractors in South Dakota will be evaluated. Additionally, in an effort to highlight the problematic mixes, aggregates and asphalt binders from recent projects that have shown stripping in the field will also be identified and tested in collaboration with SDDOT.
