• Description:
  Asphalt pavements suffer moisture damage through loss of adhesion between asphalt and aggregate (i.e., stripping of asphalt from aggregate) and due to cohesive failure of the binder. Both phenomena contribute to reductions in strength or stiffness of the asphalt concrete layer that lead to pavement distresses. Accurately predicting and mitigating moisture damage is difficult due to wide variance in aggregate types, construction practices, environmental conditions and traffic loads. The goal of this research was to identify suitable test protocols to assess the moisture damage sensitivity of asphalt concretes commonly used in Wisconsin under conditions typical to the state.
