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 on TLA modified asphalt and its mixtures were carried out, including the technical performance tests of TLA modified asphalt with different dosage, the high temperature rutting test of TLA modified asphalt mixture, the immersion Marshall test, the freeze-thaw splitting Test and seepage test. The results show that: TLA can improve the high and low temperature performance of asphalt and anti-aging properties, and can significantly improve the high temperature stability of asphalt mixture, water stability and impermeability, can be applied to China’s highway asphalt concrete pavement project.
