摘　　要：为实现公路建设的可持续发展,采用实验室自制的回收聚乙烯(MRPE)作为直投式改性剂,通过不同的制备工艺,制备相应的直投式改性沥青混合料。测试结果表明,MRPE作为直投式改性剂后,在一定程度上提升了沥青混合料的路用性能,有效的节降低了工程造价成本。In order to achieve the sustainable development of highway construction,the laboratory-made recycled polyethylene(MRPE)was used as a direct-feed modifier,and the corresponding direct-feed modified asphalt mixtures were prepared through different preparation processes.The test results show that the road performance of asphalt mixtures can be improved to a certain extent after MRPE is used as a direct-drop modifier,and the project cost can be effectively reduced.
