Research On Pavement Maintenance Technology And Pavement Condition Evaluation Of Expressway Asphalt Pavement

With the popularity of highway network, asphalt pavement’s maintance has gradually become one of the most significant issues among the issues of highway maintance.Based on the asphalt pavement’s treatment process of southern part of the west second ring road, this article did a series of researches on the detection and analysis of asphalt pavement, the characteristics and contributors of asphalt pavement’s defect and asphalt pavement’s treatment technology.Not only did this article summarize the test of asphalt pavement’s antislippery performance, deflection, smoothness and rutting, but also overviewed the testing technology and criterior of asphalt pavement’s evaluation.Besides,it provided some scientific reference information to asphalt pavement’s treatment by using the method of asphalt pavement’s testing and evaluating to analyse the condition of southern part of the west second ring road. what’s more,it summed up the typical defect and contributors of highway, especially the asphalt pavement’s defect and contributors of the southern part of the west second ring road, which offered some technology clues to the asphalt pavement’s defects. In addition, it introduced the technology of restoration of cracks,pit repair,and most importantly the Preventive maintenance technology of asphalt pavements, which inclued Seal preventive,mask preventive and recycling of asphalt pavements.Finally,it analysed Ultra thin adhesive wear layer preventive maintance used in the asphalt pavement’s maintance of southern part of the west second ring road and the treatment result of it.
