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.
