The Study Of Asphalt Treated Design And Construction Technology

Although China is still widespread grassroots highway semi-rigid base, but thedomestic road workers on flexible base material structure design, road performance,flexible base practicality, also done a lot of research, and the flexible material (asphaltstable gravel or large size asphalt concrete) has been used as the primary number ofhighway. Tianjin has yet to have flexible base material as highway grassroots attempt, northe formation of a flexible material system design methods.Therefore, this subject material for the Tianjin area, still need to use different meansof forming (GTM, the Marshall method) for flexible base material contrast design andsystem studies. The main method of using GTM asphalt macadam mixture Applicability ofmix design and performance verification, using the GTM method dense graded asphaltmacadam mixture gradation optimization and performance validation. GTM method for theuse of dense graded asphalt macadam mixture mechanical parameters of in-depth analysis,and finally using the GTM method dense graded asphalt macadam mixture gradationoptimization design example is given confirmatory analysis.
