聚合物纤维改性高性能沥青混凝土的研究

Research on Polymer Fiber Modified High Performance Asphalt Concrete

在试验研究及系统分析高性能沥青混凝土路用性能的基础上 ,选用玄武岩与国创 PG76 - 2 2改性沥青作为原材料 ,设计并制备 Super12 .5型高性能沥青混凝土 ,并通过在混合料中添加聚合物纤维来改善沥青混凝土的路用性能。试验结果表明 ,在使用纤维作为改性剂后 ,混合料的动稳定度。

According to the test and analysis field performance of the super performance asphalt concrete,this paper designed and prepared Super 12.5 mixture used basalt and Guochuang PG76 22 modified asphalt as the raw materials,By using the polyester fiber as modified material in asphalt concrete,the pavement performance of this mixture was improved.The results of the tests show that after the fiber was used as modified materials,the index of the dynamic stability,the frozen split strength were increased.
