The invention discloses a steel bridge deck pavement construction process. The steel bridge deck pavement construction process comprises the following steps that S1, a working face of a steel bridge deck slab is cleaned; s2, the working face of the steel bridge deck is subjected to sand blasting derusting treatment; s3, within 3 hours after sand blasting derusting inspection is qualified, the working face of the steel bridge deck is coated with a methacrylic resin base coating in a rolling mode; s4, after the methacrylic resin prime coat is cured, two methacrylic resin waterproof layers are continuously sprayed; s5, after the methacrylic resin waterproof layer is thoroughly cured, a methacrylic resin adhesive is immediately constructed; s6, the pouring type mixture is flatly laid on the working face of the steel bridge deck slab; s7, spraying modified emulsified asphalt tack coat oil on the surface of the pouring type mixture; and S8, paving the high-elastic modified asphalt mixture, and rolling the high-elastic modified asphalt mixture to be flat. By adopting a reasonable construction process, stable pavement of the steel bridge deck is realized, the phenomenon of fracture or deformation of the paved bridge deck is avoided. Meanwhile, the service life of the steel bridge deck is prolonged.
本发明公开了一种钢桥面铺装施工工艺，包括如下步骤：S1，对钢桥面板的工作面进行清理；S2，对钢桥面板的工作面进行喷砂除锈处理；S3，在喷砂除锈检验合格后3h内，在钢桥面板的工作面上滚涂甲基丙烯酸树脂底涂层；S4，待甲基丙烯酸树脂底涂层固化后，连续喷涂两层甲基丙烯酸树脂防水层；S5，待甲基丙烯酸树脂防水层彻底固化后，立即施工甲基丙烯酸树脂胶粘剂；S6，将浇注式混合料平整的摊铺在钢桥面板的工作面上；S7，在浇注式混合料表面洒布改性乳化沥青粘层油；S8，将高弹改性沥青混合料进行摊铺，并碾压平整。本发明通过采用合理的施工工艺，实现钢桥面的稳定铺装，避免铺装后的桥面产生断裂或变形现象，同时提高钢桥面的使用寿命。
