EFFECTS OF MOISTURE ON PROPERTIES OF ASPHALT

EFFECTS OF MOISTURE ON PROPERTIES OF ASPHALT MIXES IN A WET TROPICAL CLIMATE: A LABORATORY STUDY. A moisture treatment designed to simulate the condition that pavements are exposed to in the wet tropical climate of Singapore is described. A weathering chamber was specially fabricated to introduce simultaneous wetting-drying and thermal cycles.

Moisture-Induced Damage Characterization of Asphalt

The results of the SFE parameters and chemical analyses indicated that the properties of aggregates have significantly higher influence on the moisture-induced damage potential of a mix than the properties of binder. Also, asphalt mixes, in general, were found to become more prone to moisture-induced damage with in-service aging.
