Study On The Common Diseases Treatment Of Asphalt Pavement For Freeway

With the continuous growth of China’s freeway mileage of freeway has become an important infrastructure for economic development. After the freeway was opened to traffic, due to the joint effect of traffic load, the natural environment and other factors, the asphalt road surface early in varying degrees, the different types of damage phenomena. Overall, the main types of freeway asphalt pavement cracks, potholes, ruts, loose, net crack, crack. Over time, these diseases increasingly serious, if not timely repair, will directly affect the performance of pavement maintenance work has become essential. In view of this problem, we propose a standardized method of the Freeway Asphalt Pavement Disease Treatment in order to guide the asphalt pavement maintenance operations.In this paper, we summarize, sum up the high-speed road based on the type of disease, analyze the causes of various diseases resulting pavement; domestic and foreign research and collect pavement maintenance technology; compared to the current general approach Pavement Disease Treatment of Diseases typical of freeway maintenance technology for analysis, a comprehensive analysis of the advantages and disadvantages of various techniques, recommended a freeway asphalt pavement Common Diseases: cracks, potholes, rutting conservation techniques, and various conservation techniques comprehensive analysis, standardization Treatment program. Through the study of freeway asphalt pavement maintenance technology to make conservation technology to achieve scientific, standardized, so that the road for longer life and improve the road service levels, reduce costs throughout the life cycle.
