目前我国沥青混凝土路面的车辙问题日益突出,使用抗车辙剂能够有效地提高沥青混合料的高温性能。同时,考虑到产生车辙的一个重要原因是沥青混凝土路面高温条件下在车辆荷载作用下的剪切变形,引入了抗剪强度指标,来综合评价沥青混合料的高温性能。 At present, the rutting problem of asphalt concrete pavement in our country is increasingly prominent. The use of anti-rutting agent can effectively improve the high temperature performance of asphalt mixture. At the same time, taking into account the rutting is an important reason for asphalt concrete pavement under high temperature conditions under the vehicle load shear deformation, the introduction of shear strength index to comprehensively evaluate the high temperature performance of asphalt mixture.
