摘　　要：城市桥梁桥面铺装容易出现沥青混凝土破损、开裂、坑洼、拥包等病害,严重影响行车舒适性,容易加剧城市道路拥堵。本文针对连续梁桥墩顶处沥青混凝土铺装开裂、曲线桥桥面沥青混凝土裂缝、车辙以及坡桥坡脚处桥面沥青混凝土坑洞、水损坏等三类典型桥面病害进行研究,从结构受力、材料特性、桥梁所处环境等方面分析了病害的成因,提出了病害防治建议,可供类似工程项目借鉴参考。Urban bridge deck pavement is prone to asphalt concrete damage, cracking, potholes, sacks and other diseases, which seriously affect driving comfort and easily aggravate urban road congestion. This paper studies three typical bridge deck diseases: continuous beam pier top asphalt concrete pavement crack, curved bridge deck asphalt concrete crack, rutting, slope toe bridge deck asphalt concrete pothole and water damage, analyzes the causes of the diseases from the aspects of structural stress, crack, crack and water damage, and puts forward disease prevention suggestions, which can be used as a reference for similar projects.
