摘　　要：针对某项目市政道路拟使用PE改性沥青混合料,为了获取PE改性剂的最佳掺量,针对PE改性沥青混合料的配合比进行分析。采用PE改性沥青性能试验的方法,分析改性沥青的主要性能和PE改性沥青混合料的路用性能。结果表明,该混合料高温稳定性强,低温具有一定抗裂性,在市政路面修建中具有一定的使用价值。In view of the municipal road of a project to use PE modifi ed asphalt mixture, in order to obtain the best mixing amount of PE modifi er, the mixture ratio of PE modifi ed asphalt mixture was analyzed. The main properties of the modifi ed asphalt and the road performance of the PE modifi ed asphalt mixture were analyzed by means of performance test. The results show that the mixture has strong stability at high temperature and crack resistance at low temperature, so it has certain application value in the construction of municipal pavement.
