PE胶粉复合改性沥青及沥青混合料性能研究

Research on Performance of Compound Modified Asphalt of PE Rubber Powder and Asphalt Mixture

为了研究PE胶粉复合改性剂对沥青及沥青混合料性能产生的影响,以室内试验为基础,对比分析了SBS改性剂、胶粉改性剂和PE胶粉复合改性剂对基质沥青及AC-20型沥青混合料性能的影响。试验结果表明,PE胶粉复合改性沥青混合料高温性能及水稳性能优越,低温性能也较好,既环保又经济,建议在新疆地区推广应用。

In order to study the influence of compound modifier of PE tubber powder on the pefformance of asphalt and asphalt mixture, taking the laboratocy test as the basis, the influence of SBS modifier, modifier of rubber powder and compound modifier of PE rubber power on the performance of matrix asphalt and AC - 20 asphalt mixture is compared. The test results show that, the high temperature pefformance and water stability pefformance of compound modified asphalt mixture of PE tubber powder are excellent, the low temperature performance is also better, which is not only environmental friendly but also economic. It is suggested to popularize and apply in Xinjiang area.
