Asphalt Pavement Cause Analysis Of The Early Damage And Preventive Measure

With a large number of highway construction , asphalt pavement have been more widely used, especially semi-rigid asphalt pavement for our highway asphalt pavement most. Have been built from the use of high-grade highways, many roads are a serious early damage. If the asphalt pavement early damage can be completely resolved, the annual savings would be siginificant on highway construction investment. Improving capacity and service quality of the operation, the study early asphalt pavement damage is significant. This paper introduces the semi-rigid characteristics of the asphalt pavement, followed by the destruction of the phenomenon and its causes summarized analysis, then a freeway pavement example, the road structure of the analysis and calculation of the reasons for undermining research, finally, asphalt pavement damage early preventive measures.
