摘　　要：通过包含应力吸收层的复合试件的疲劳试验,分别对胶粉沥青应力吸收层、聚酯玻纤布应力吸收层、乳化沥青封层、热喷沥青粘层和加铺土工格栅五种应力吸收层的抗疲劳性能进行试验分析比较,结果表明胶粉沥青应力吸收层的路用性能优于其他类型。By the drawing experiment of the combined specimen of stress absorbing layer, fatigue resistance of five kinds of stress absorbing layer are analyzed and compared respectively. The five kinds of stress absorbing layer are the performances of rubber asphalt stress absorbing layer, polyester bolivia filament cloth stress absorbing layer, emulsified asphalt seal coat, hot spraying asphalt tack coat and geogrid overlay. The experiment results show that the performances of rubber asphalt stress absorbing layer is better than that of the others.
