沥青桥面铺装水损害原因及预防措施分析

The analysis and preventive action of water damage cause for bridge deck of asphalt

公路桥梁的桥面铺装层承受车辆等荷载作用,是最直接的多向受力结构层,当前,沥青混凝土桥面破坏的一个主要问题是水损害。所以,在对沥青混凝土桥面水损害原因进行详细分析的基础上,结合高速公路所采取的工程防止措施及使用效果,对沥青混凝土桥面防治早期水损害对策进行了初步研究,提出桥面设计时应注意防水的设计,并提高桥面铺装水稳性,注重日常养护等预防措施。

Bridge deck pavement of roads and bridge is for bear load effect of vehicles,and it is the most straight Multidirectional stress structure layer.At present,one of the major bridge deck diseases of Asphalt concrete is water damage.Therefore,on the basis of analysis in bridge deck water diseases of Asphalt concrete,we should combine the engineering measures and using effects which highway adopted,and carry out the preliminary research of early water diseases prevention measures in Asphalt concrete pavement.At the same time,the water prevention design should be noticed when bridge design is brought out,and improve the water stability of bridge deck pavement as well as pay attention to the daily maintenance of preventive measures.
