DF68. A case study of the premature failure of a trial road in Dak Lak province, Vietnam. (SEACAP24 Paper).
In response to the increasing recognition that gravel surfacing was not a universal solution for rural roads in Vietnam, the Ministry of Transport (MoT) in 2002 requested studies of alternative surfaces for rural roads. These studies became known as the Rural Road Surfacing Research (RRSR) initiative, through which the Rural Road Surfacing Trials (RRST I and RRST II) were carried out. This research programme and its extensions were incorporated into the DfID-funded South East Asia Community Access Programme (SEACAP). Three trial roads were constructed in Dak Lak province under the RRST-II programme (2005-2006). The trial roads in Dak Lak were completed by July 2006 and shortly after that in December 2006 the Buon Ho road was reported to have suffered rapid deterioration on some sections. Reasons for the failure of this road are discussed.
