沥青混凝土桥面排水系统分析与设计

Asphalt concrete bridge deck drainage system analysis and design

通过水对桥面铺装结构以及行车安全的不利影响的分析,提出沥青混凝土桥面铺装层表面及内部排水系统方案,该方案将排水系统分为独立的表面排水系统和铺装层内部排水系统两个部分,强化了桥面横坡形成层(找平层)的作用。该方案能加快层间水排出的速度,增强桥面铺装层的强度和稳定性,从而确保结构耐久性的要求。

Based on water on deck pavement structure and the harmful effects of traffic safety,the analysis of asphalt concrete bridge deck pavement surface and internal drainage system solutions is put forward;drainage system is divided into independent surface drainage system and internal drainage system surfacing layer of two parts;strengthened the bridge deck cross-sectional slope procambium（screed-coat） role.The scheme can accelerate the speed of no-flow periods between the layers,and enhance the bridge deck pavement of strength and stability,and the durability of the requirements.
