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。
