WATER EFFECT ON DETERIORATIONS OF ASPHALT PAVEMENTS

Moisture damage can be defined as the loss of strength and durability in asphalt mixtures caused by the presence of water. Moisture damage is induced by the loss of bond between the asphalt cement or the mastic (asphalt cement, the mineral filler and small aggregates) and the fine and coarse aggregate.

Types of Asphalt Deterioration

Depressions in asphalt are formed due to improper construction and/or a combination of both inadequate base and load distress. When moisture infiltrates pavement, it tends to undermine the stone base causing it to hold water. This happens most commonly in longitudinal cracking. Depression is also the first warning sign of alligator cracking and ...
