在重载道路沥青路面中,上面层或上、中面层采用高耐流动性沥青混合料。近年来聚合物改性沥青Ⅱ型、Ⅲ型作为耐流动性混合料的胶结料虽然得到普遍应用,但在对混合料性能有明确要求的工程中,有必要对采用聚合物改性沥青的热拌沥青混合料动稳定度的适用性进行评价。该文对改性沥青混合料耐流动性评价方法和评价指标与车辙的关系,采用日本土木研究所和日本道路建设业协会联合研究的“路面及路面用胶结料性能评价”课题成果进行分析。 In heavy road asphalt pavement, the upper layer or upper and middle surface with high flow resistance asphalt mixture. In recent years, polymer modified bitumen type Ⅱ, Ⅲ as the fluidity of the mixture of cementitious materials have been widely used, but in the performance of the mixture has clear requirements of the project, it is necessary for the use of polymer modified asphalt heat The suitability of dynamic stability of asphalt mixture was evaluated. The article on the evaluation of resistance to modified asphalt mixture and evaluation methods and rutting relationship, using Japan Civil Engineering Institute and Japan Road Construction Association jointly study “pavement and pavement with binder performance evaluation ” project achievements analysis.
