PE类聚合物用于SMA-13沥青混合料的路用性能研究

Study on performance of PE polymer used in SMA-13 asphalt mixture

针对目前的SMA沥青混合料路面,普遍采用的是SBS改性沥青,因其施工工艺难度高,成本造价昂贵,在此基础上展开了PE类聚合物改性剂在SMA-13型沥青混合料中的应用研究。

For the current SMA asphalt mixture pavement, SBS modified asphalt is commonly used. Because of its difficult construction process and high cost, the application of PE polymer modifier in SMA-13 asphalt mixture was studied.
