Recent research in S E Asia and Vietnamin particular, funded by the World Bank and DfID since 2003,has focused on improving rural community access through moresustainable low volume rural road design. More appropriatedesign ensures that roads built are cost effective in termsof whole life performance. Because of increasing recognitionthat gravel surfacing was not always the best solution forrural roads in Vietnam, the initial research focused on theperformance of existing unsealed roads and theidentification of sustainable alternatives. Subsequentresearch has focused on the relative performance of thealternative option trials and their role in providing a moreclimate resilient rural infrastructure. In general, thiswork has concentrated on a range of pavements to establishthe best performance within a range of physical andsocio-economic environments. This note highlights thefindings of the Rural Road Gravel Assessment Programme(RRGAP) and the Rural Road Surfacing Trials (RRST phases I,II and III) undertaken within Vietnam under the umbrella ofthe Ministry of Transport Rural Road Surfacing Research(RRSR) committee. Outcomes were enhanced by information fromcomplimentary projects within Lao PDR and Cambodia.
