同步碎石下封层对沥青路面结构力学响应的影响分析

Effect of Synchronous Bottom Gravel Seal Coat on Mechanical Response of Asphalt Pavement Structure

在半刚性基层上设置同步碎石下封层可有效减少沥青面层反射裂缝的产生。采用ANSYS有限元计算软件对设置同步碎石下封层的半刚性基层沥青路面结构的力学反应进行分析,计算出同步碎石下封层参数变化对半刚性基层沥青路面力学性能的影响。

Setting the synchronous bottom gravel seal coat on the semi-rigid base can effectively reduce the reflection of cracks of asphalt surface layer. This article uses ANSYS finite element software to analyze the me- chanical reaction of semi-rigid base asphalt pavement construction with the synchronization gravel seal coat. The influence of the change of parameter of synchronous bottom gravel seal coat on the mechanical properties of se- mi-rigid asphalt pavement is also calculated.
