不同抗车辙剂沥青混合料使用性能试验研究

摘要

结合衡桂高速公路骨架密实级配AC - 20的使用情况,比较了添加不同抗车辙剂的沥青混合料的高温稳定性、水稳定性和低温抗裂性.发现三种抗辙剂能显著提高沥青混合料的高温稳定性,同时能改善沥青混合料的低温抗裂性和水稳定性.根据试验结果,抗车辙剂A路用性能最佳.%Combining Henggui Expressway skeleton dense gradation AC-20 use case, compare with adding different anti rut asphalt mixture high temperature stability, water stability and low temperature crack resistance. Discover three kinds of anti rutting agent can significantly improve the high temperature stability of asphalt mixture, and can improve the asphalt mixtures at low temperature and water stability. According to the test results, anti rutting agent A is the best choice.
