水泥混凝土梁桥沥青铺装结构设计方法探讨

Study on concrete beam bridge asphalt pavement structure design method

以高速公路水泥混凝土梁桥沥青铺装层结构受力分析为基础,对复合桥面铺装结构设计方法进行了探讨,提出以沥青铺装层表面最大拉应力和最大剪应力分别作为结构设计的主要指标和辅助指标,同时对沥青混凝土桥面铺装结构设计方法及流程进行了总结,并进行了实例计算。

Based on structure stress analysis on asphalt concrete bridge deck pavement of highway concrete bridge, the design methods of bridge deck asphalt concrete pavement structure have been discussed in this paper, it has been put forward that, as for structure design of asphalt concrete pavement, the maximum tensile stress could be used as the main index and the maximum shear stress could be used as auxiliary index, meanwhile, the design method and process of asphalt concrete deck pavement structure have been summed up, as well as with case calculation.
