摘　　要：针对我国高速公路沥青混凝土桥面铺装普遍发生的泛碱病害,通过化验分析及现场实测等手段分析了病害产生的机理及原因,同时简要分析了桥面铺装泛碱病害的危害,进而从桥面铺装泛碱病害可能发生的原因层面提出相应的预防措施,并针对已经存在桥面铺装泛碱病害的项目提出对应的处治建议。通过文中的相关分析以期引起我国高速公路桥面铺装建设单位的高度重视,并积极采取切实可行的措施进行防治。Aiming at the common efflorescence defects of asphalt concrete bridge deck pavement on expressways in China,the mechanism and causes of the defects are analyzed by means of laboratory analysis and field measurement.At the same time,the damage of saltpetering on asphalt concrete bridge deck pavement is briefly analyzed.Then the corresponding preventive measures are put forward from the possible causes of the defect,and the corresponding treatment suggestions are put forward for projects that have been used for spreading crystalline bloom.Through the relevant analysis in this paper,it is expected that contractors of expressway bridge deck pavement in China can attach great importance to such defects and take active and feasible measures to prevent and control it.
