| Abstract: | A series of laboratory tests of TLA modified asphalt and its mixture are made.These include different content TLA modified asphalt technical property tests,TLA modified asphalt mixture rutting test at high temperature,Marshall test and freeze and thaw split test,and permeability test. The results showe that TLA can improve the stability performance of asphalt at high temperature and low temperature and anti-aged performance,and it is very effective to improve the stability performance of asphalt mixture at high temperature,the capacity of moisture-resistance damage and impermeability.So it can be applied to asphalt concrete pavement engineering of expressway in China. |
