The State-of-Practice Reclaimed Asphalt Pavement in Vietnam

Abstract

The total length of road network in Vietnam is over 20,000kilometers. Millions of cubic meters of materials for pavement construction and rehabilitation are required every year. Vietnam has to import asphalt binder. Good quarry resources are located far from big city and quickly reducing in quantities. Thus, reclaimed asphalt pavement (RAP) technology is considered as the key to reduce the cost and preserve natural environment. After nearly ten years studies this technology, the practice of the technology is still limited in Vietnam. This paper is a describing of reclaimed asphalt pavement technology in practice of Vietnam. Only one of four RAP process are widely applied, although the chosen RAP process may not efficient in all cases.
