Improving Vietnam’s sustainability : key priorities for 2014 and beyond (Inglês)

The rural road gravel assessment program (RRGAP) comprised the evaluation of a representative selection of 269 World Bank (WB)-funded road links from 16 provinces. Between 2003 and 2012 three phases of trial road selection, design, and construction were undertaken under the RRST program. The objective was to compare new pavement options in terms of construction and in-service performance against a number of standard Vietnamese control sections, monitoring of the trial sections commenced as soon as construction was completed. A total of 156 kilo meter (km) of trial roads have been constructed within a range of road environments in 16 provinces, from which a representative 123 sections of between 80m to 200m in length have been selected for ongoing performance monitoring. The condition monitoring of the Vietnamese trials has resulted in the assembly of a significant amounts of data on the performance of a wide variety of pavement and surfacing types.
