WATER-INDUCED DISTRESS IN FLEXIBLE PAVEMENT IN A WET TROPICAL CLIMATE

A wet tropical climate characterized by abundance of rainfall and cool nights followed by hot days offers a favorable environment for the development of water-associated distress in flexible pavement. Surface deteriorations such as stripping and raveling have been widely reported and studied in the literature. Other forms of water-induced distress, which are caused by water trapped within the structural system of a flexible pavement, are described in this paper. The occurrence of such distress is difficult to predict, and the subsequent repair is usually quite costly and elaborate. A number of cases of water-induced distress in flexible pavement in Singapore and Malaysia are presented and discussed. The need for drainage analysis in pavement design and the importance of drainage consideration in pavement construction and maintenance are highlighted. On the basis of relevant experience in the region, some preventive measures are recommended for guarding against water-induced problems in flexible pavement.
