Shortly after its completion in 2006 the Buon Ho RRSR trial road in Dak Lak Province, Vietnam, was reported to have suffered rapid deterioration on some sections. These trial sections of the Buon Ho road were designed with four different pavement options based on existing Commune Class A standards and the research guidelines developed for the RRSR programme. The objectives of this report are to summarise the SEACAP 24 work undertaken on the Buon Ho 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.
