Early Diseases of Asphalt Pavement Damage of Water Research and Countermeasures

The life cycle of a road engineering usually contains multiple stages. It starts from design, through the construction, usage and damaged to discarded. Early disease water damage of asphalt pavement has great influence on the service life of road surface. Through analyzing the mechanism of water damage and summarizing the main forms of water damage, this paper puts forward the reasonable distribution of asphalt mixture and the good rigidity relationship between base and surface, which is the key factors to avoid water damage. We analyze and summarize the advantage of drainage asphalt pavement in the prevention and control of water damage of asphalt pavement in order to apply it in the practice of engineering.
