Study On The Comprehensive Performance Of Road Asphalt

As time goes on, the economy of our country has gradually developed,among them,in the field of highway construction are also gradually increasing.Increase investment alsomake China’s highway mileage number increasing, but our country’s highway asphalt roadbedusage is not good.Just put into use in2-3years,it may appear overhaul maintenance, evensome asphalt layer appeared early destruction cracking, rutting, water damage, etc whenusing soon As a result, the research on road performance of asphalt is particularlyimportant.This paper mainly analysis and research from The performance of the pavementmaterials and road asphalt.On the basis of reference papers at home and abroad research, thispaper adopt the method of combining theory with experiment to analysis and discuss.Duringanalysis, this thesis mainly uses the method of comprehensive comparison with horizontaland vertical analysis.First of all,the11kinds of asphalt shall be carried out in accordance withthe type classification,Second, according to the11kinds of asphalt penetration levelclassification, divided into the penetration of asphalt,70,90,110and130,and then analysisand compare.By11kinds of asphalt conventional and technical performance test in qinghai,itmainly include penetration, softening point, ductility and elastic recovery, etc., to analysis thetechnical performance indicators of asphalt relationship.thus,it provides the basis ofconventional aspects on quality of road asphalt evaluation.And last,through the dynamic ofthe11kinds of asphalt beam shear, bending and other SHRP test technical performanceindicators and road asphalt SHRP technical performance have been obtained, the relationshipbetween the quality of the asphalt for road evaluation provides the basis of SHRP technicalperformance indicatorswith best based on the different road asphalt four components test,weget the micro performance index of the asphalt roads for quality evaluation of road asphalt toprovide the basis of the microscopic analysis.with the technical performance of asphalt road test,on the basis of analysis of roadasphalt evaluation with comprehensive analysis of test index of the evaluation results, thus,providing a basis for controling the quality of road asphalt the popularization and application.
