• Abstract:
  Moisture susceptibility of hot mix asphalt (HMA) pavements continues to be a major pavement distress. Past research ; has primarily focused on HMA stripping prevention through material component evaluation/testing and addition of ; preventative additives. Stripping is caused by traffic, water, and high in-place service temperatures. Today, agencies ; use various methods to evaluate HMA moisture susceptibility with varying degrees of success. ; The study objective was to evaluate a prototype stripping simulator’s ability to predict HMA moisture susceptibility. ; The simulator evaluates moisture susceptibility by measuring conditioning water turbidity. Boil test and indirect ; tensile strength testing were also conducted for comparison purposes. Stripping simulator results indicate further ; refinement is required before it can be used for moisture susceptibility prediction.
