沥青混凝土桥面铺装防水技术

文章从沥青混凝土桥面铺装质量的主要影响因素入手进行分析,进而分别从不同层间接触状态、沥青铺装体系最不利荷载位置、沥青铺装层不同厚度的层间应力、行车超载等影响因素对桥面铺装层间应力特性进行分析与了解。对防水材料的实际运用效果进行了铺装实验,在这基础上总结出了桥面柔性防水层的施工工艺和质量检测验收方法。

Based on the analysis of the main factors affecting the quality of asphalt concrete bridge deck pavement, the paperanalyzes and studies the stress characteristics of bridge deck pavement from the following factors： the contact state between differentlayers, the most unfavorable load location of asphalt pavement system, the interlayer stress of different thickness of asphalt pavement,traffic overload and so on. On the basis of the practical application effect of the waterproof material, the pavement experiment is car-ried out, and the construction technology and quality inspection and acceptance method of the flexible waterproof layer of the bridgedeck are summarized.
