Study On The Performance Evaluation And Preventive Maintenance Measure Of Asphalt Pavement In Xinjiang Region

The road traffic is the basis facilities for the development of a regional economic,pavement performance directly determine their level of service. Conservation andmanagement departments through road condition surveys to obtain basic data thenevaluate pavement performance, based on the above to establish the maintenancestrategy, which is the key of the pavement management system. Preventive Maintenanceas a "rainy day" curing way can make the road to maintain a good level of service, butalso reduce the maintenance costs of the road service life.This paper analyzes the working conditions of the asphalt pavement, relevantcharacteristics and influencing factors and evolution by the research of asphaltpavement performance evaluation and pre-conservation technology in Xinjiang region,identification and causes of common diseases of asphalt pavement, laid the foundationfor the late asphalt pavement performance evaluation.Based on the analysis of each individual index for evaluation of asphalt pavement,combined with the characteristics of the Xinjiang region, this paper put forwardcorrection method for the sub-index. Aiming at the complexity of asphalt pavementperformance evaluation, we use multi-index comprehensive evaluation method based onBP network through the network training, the establishment of an evaluation modelcloser to human thinking mode, experts thought is given to the network, so the networkcan simulate quantitative evaluation of the experts.Based on the study of asphalt pavement performance evaluation methods, thispaper analyzes the connotation of pre-conservation and the limiting factor in thepromotion and application. Through analysis of the mechanism, the constructiontechnology, it is recommended to apply pre-conservation measures.
