Reversible moisture damage in asphalt mixture

A moisture damage has been one of the major concerns for HMA pavement by loss of adhesion between asphalt binder and aggregate surface or loss of the cohesion within asphalt binder due to action of water. Water is the one of major contributor towards the damage of asphalt pavement. The aim of this r...
