摘要
对TLA改性沥青及其混合料进行了一系列室内试验研究,包括不同掺量的TLA改性沥青的技术性能试验,TLA改性沥青混合料的高温车辙试验、浸水马歇尔试验、冻融劈裂试验和渗水试验。研究结果表明:TLA能改善沥青的高、低温性能和抗老化性能,而且能明显提高沥青混合料的高温稳定性、水稳定性和抗渗性,可应用于我国高速公路沥青混凝土路面工程中。
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.
