Based on high viscous asphalt, this paper mainly studied the following four topics: Firstly, FEM (finite element method) was used to analyze the effect of stress absorbing layer.

本文以高粘性沥青为结合料，主要对以下四方面内容进行了研究：首先，用有限元方法计算分析应力吸收层防治反射裂缝效果。

SAF stress absorbing layer has very good ability to resist reflective cracks. Because of its air-free and little water permeability, it can decrease the damage caused by water in the pavement.

SAF应力吸收层系统具有良好的抗反射裂缝能力，混合料密实、透水性小，可以减少路面水损坏的产生，用该结构可以有效解决旧路加铺时反射裂缝的产生。
