Moisture susceptibility is a primary cause of distress in HMA pavements. HMA should not degrade substantially from moisture penetration into the mix. HMA mixtures may be considered susceptible to moisture if the internal asphalt bindertoaggregate bond weakens in the presence of water. This weakening, if severe enough, can result in stripping (Figure 1).
