水泥混凝土桥面铺装防水粘结层研究

Study on waterproof bonding layer of cement concrete bridge deck pavement

为了保证水泥混凝土桥面防水粘结层具有足够的强度、防水性能以及与铺装层间良好的变形协调能力,特别是防水粘结层的抗施工损伤性能,对SBS改性沥青+碎石、改性乳化沥青、水性环氧沥青等三种典型防水粘结层材料的粘结强度、水稳定性、防渗透性能进行系统研究,从而优选出综合性能优异的防水粘结层材料,为今后水泥混凝土桥面铺装防水粘结层的选择提供理论依据。

In order to ensure that the waterproof adhesive layer has enough strength,waterproof and good compatibility with the pavement,especially the construction damage performance of waterproof adhesive layer. In this study,the bond strength,water stability and infiltration prevention of three typical waterproof adhesive layer materials,including SBS modified asphalt,gravel,modified emulsified asphalt and waterborne epoxy asphalt,were systematically studied. And selected the excellent performance of waterproof layer material. It provides a theoretical basis for the selection of waterproof adhesive layer for cement concrete bridge deck pavement in the future.
