The Applicability Research Of Asphalt And Asphalt Mixture

This text mainly aims at the applicability of asphalt and asphalt mixture to open research, and puts forward some suggestions about choosing an asphalt species and mark number,the type of mixture,and thickness of asphalt road surface for area in our country everyplace.It is general basis experience in our country while choosing the asphalt mark number and species, but the fulfillment express that there is greatly difference of same mark number different species, and the wrong choice of asphalt species and mark number in some engineering project results the different degree breakage phenomenon in highway road surface and lowering the service life of asphalt road. Hence this test first collects the normal experiment result of common used A class substrate asphalt species and mark nmber in our country and counts and analyzes these experiment data making use of the SPSS statistics software to getting the statistics result of each index as the same time as carry on asphalt applicability research, and then further analyzes its usage making use of above-mentioned statistics result in order to offer reference about the choice of asphalt species and mark number, reduce the breakage phenomenon of asphalt road and raise its service life.Now there are many types of common used asphalt mixture and each type of mixture has its respective characteristic and applicable scope, so the choice of mixture type should accord to the actual circumstance of every place and avoid blindly pursuing the quality good or bad of the mixture. This text collects asphalt road surface structure of some high grade highway in our country, and summaries present development condition and trend of asphalt road from it, and puts forward extensive adoption of modification asphalt technique and skeleton gradation, besides further studies the applicable material and thickness of top layer,medium layer and bottom layer of asphalt road surface, and tries to make asphalt road has resisting high temperature rutting and low temperature cracking and good water stability, in order to prolong the service life of road and raise the total quality of asphalt road in our country.
