TLA改性沥青混合料路用性能研究

Research on road performance of TLA modified asphalt mixture

对掺量为30%,33%,36%,40%的TLA改性沥青进行了室内试验,并对这些掺量下的TLA改性沥青混合料进行了浸水马歇尔试验、高温车辙试验、冻融劈裂试验、表面构造深度试验和飞散试验,研究表明,TLA改性沥青具有较高的水稳定性、抗高温车辙能力、抗滑性、抗渗性等优良的路用性能,有非常好的推广应用前景。

In this paper, the content of 30 %, 33 %, 36 % and 40 % of the TLA modified asphalt for the laboratory test, a series of laboratory tests were performed on TLA modified asphalt mixtures, including soggy Marshal test, wheel tracking test, freeze and split test, Surface structural depth test, cantabro test, etc. Research indicates that TLA modified asphalt mixture has an excellent road performance, such as high water-stability, anti-rutting capacity, antiskid property and anti-permeability and so on. There will be a large market and bright future.
