高速公路沥青混凝土路面车辙问题是困扰公路界的一大难题。通过采用东海A-70及东海SBS改性沥青,对4种AC-20沥青沥青混合料高温稳定性、低温性能及水稳定性进行了室内研究。试验结果表明:抗车辙剂可显著提高沥青混合料高温稳定性,降低沥青混合料温度敏感性,同时可以提高沥青混合料水稳定性,且低温性能降低较小。掺抗车辙剂沥青混合料可满足南方高温多雨地区的需要,具有一定的推广价值与应用前景。
Asphalt concrete highway rutting problem is plagued highway community a major problem. By using the East China Sea A-70 and the East China Sea SBS modified asphalt, four kinds of AC-20 asphalt mixture high temperature stability, low temperature properties and water stability were studied indoor. The test results show that the anti-rutting agent can significantly improve the high temperature stability of asphalt mixture, reduce the temperature sensitivity of asphalt mixture, improve the water stability of asphalt mixture and lower the low temperature performance. Addition of anti-rutting asphalt mixture can meet the needs of high temperature and rainy areas in the south, which has certain promotion value and application prospect.
