蓄盐类抑制冻结沥青混合料高温性能研究

Research on high temperature stability of including salt anti-freezing asphalt mixture

为了研究蓄盐类抑制冻结沥青混合料的高温抗车辙性能,选取普通沥青混合料、抑制冻结沥青混合料及掺橡胶颗粒的抑制冻结沥青混合料,分别进行干法车辙试验和浸水车辙试验,结果表明:无论干法车辙或是浸水车辙,掺橡胶颗粒的抑制冻结沥青混合料都拥有良好的高温性能,优于其他两种沥青混合料。

In order to evaluate the high temperature performance of including salt anti-freezing asphalt mixture,ordinary asphalt mixture,anti-freezing asphalt mixture and anti-freezing asphalt mixture with rubber particles were chosen to carry out high temperature rutting test and immer-sion rutting test. The results show that whether there is the role of water or not,anti-freezing asphalt mixture with rubber particles shows more ex-cellent high temperature performance,compared with other two asphalt mixture.
