Study On The Analysis And Evaluation Of Xinjiang Composite Pavements Performance

According to the survey and evaluation of condition and performance of Xinjiangcomposite pavement，Traffic composition，pavement structure，usage，etc，wereinvestigated and tested in a typical sections. Combin with research situation and the climatecharacteristics of xinjiang，Through the summary of the road surface disease mechanism andprevention measures，analysis and evaluation was carried on the subgrade pavement condition，according to the design parameters of each layer，analysis and research to the compositepavement under the different conditions of stress. Discussion the use effect and suitability ofexisting structure types in the Xinjiang area. Through the theoretical calculation，In-depthanalysis is made through the software of BISRA，during analyze process，consider various factorof the mechanical properties influence of pavement structure. Through the engineeringcharacteristics，the typical pavement serviceability and the analysis of existing problems，which verifies the feasibility and economical rationality of technology of typical structure of theoriginal design on the road. Analyzes to Engineering properties of typical pavement,applicability and problems, typical structure of the original design of pavement technicalfeasibility and economic reasonableness has been validated.This paper is closely associated with engineering practice，For the study of Urumqi fastroad sections and TU-WU–DA road section. Consider the Survey and performance evaluation tothe Subgrade and pavement. Pointed out that the composite pavement structure arid climaticconditions and large temperature changes in traffic volume under the environment in Xinjianghas good durability and adaptability.
