以港珠澳大桥桥面铺装工程为研究背景,针对组合连续梁桥混凝土表面环氧树脂下封层撒布不同粒径碎石与防水黏结层层间性能的敏感性影响,以黏结强度和剪切强度作为防水黏结层层间性能评价指标。研究结果表明:环氧树脂下封层+碎石(0.6~2.36mm)+双层溶剂型黏结剂[(0.2+0.2)kg/m2]具有良好的层间性能。 Taking the bridge deck pavement of Hong Kong-Zhuhai-Macao Bridge as a research background, in view of the sensitivity of the epoxy resin under the concrete surface of the composite continuous girder bridges to spread the properties between different size gravel and waterproof adhesive layer, Tensile strength as a waterproof adhesive layer performance evaluation index. The results show that: the epoxy resin under the seal + gravel (0.6 ~ 2.36mm) + double-solvent adhesive [(0.2 + 0.2) kg / m2] has good interlayer performance.
