Moisture damage has been reported as one of the main forms of distress in asphalt mixtures since the 1900s. The bond between asphalt aggregate constituents fails in the presence of water interacting at the interface, resulting in the stripping of binder from the aggregate surface and cohesive failure within the asphalt binder. This paper reviews various techniques and investigations for assessing the moisture damage and aims to optimize the standard testing protocols. The introduction of new in-situ testing techniques and material selection criteria is required to address the moisture susceptibility of asphalt mixtures. These efforts can improve the field assessment of moisture damage that appears during the design life of an asphalt pavement and bridge the gap between field and laboratory investigations.
