SEACAP 24. Case Study of pavement and surface deterioration on trial roads - Ea Soup road.

Abstract

Shortly after its completion in 2006 the Ea Soup RRSR trial road in Dak Lak Province, Vietnam, was reported to have suffered rapid deterioration in a particular section. An investigation contract was agreed between SEACAP/DfID and TRL Ltd and their Associates in September 2007 and a programme of field investigations undertaken which included desk studies, walkover surveys, inspection pits, in situ testing; laboratory testing and traffic analysis. The objectives of this report are to summarise the SEACAP 24 work undertaken on the Ea Soup road, present the results of this work, and then discuss them in relation to the likely cause or causes of the pavement deterioration. Recommendations as to the prevention of similar failures occurring in the future programmes are also presented.
