Bridge floor high-toughness ultrathin wearing layer and construction method of high-toughness ultrathin wearing layer
The invention discloses a bridge floor high-toughness ultrathin wearing layer which is used for being paved on a cement concrete bridge floor, the thickness of the bridge floor high-toughness ultrathin wearing layer is 1-2cm, the bridge floor high-toughness ultrathin wearing layer comprises a hot-mixing ultrathin finishing coat and a bonding waterproof layer, and the bonding waterproof layer is used for connecting the hot-mixing ultrathin finishing coat and a cement concrete layer of the bridge floor; the hot-mixed ultrathin finishing coat is prepared from the following components in parts by weight through open grading: 100 parts of mineral aggregate, which comprises 77-87 parts of coarse aggregate, 8-18 parts of fine aggregate and 4-6 parts of mineral powder filler; 5.5 parts to 6.5 parts of high-viscosity modified asphalt; and 0.1-1 part of an anti-stripping agent. The invention further discloses a construction method of the bridge floor high-toughness ultrathin wearing layer. Compared with the prior art, the bridge floor high-toughness ultrathin wearing layer formed by combining mixture ratios provided by the invention with the corresponding construction method has excellent cohesive force, water resistance, stripping resistance and aging resistance, and can effectively improve the driving safety and comfort.
本发明公布了一种桥面高韧超薄磨耗层，用于铺筑在水泥混凝土桥面，所述桥面高韧超薄磨耗层的厚度为1～2cm，其包括热拌超薄罩面层和粘结防水层，所述粘结防水层用于连接热拌超薄罩面层和所述桥面的水泥混凝土层，所述热拌超薄罩面层采用以下用量比的成分开级配而成：矿料100份，包括粗集料、细集料和矿粉填料，其中粗集料77～87份，细集料8～18份，矿粉填料4～6份；高粘改性沥青5.5份～6.5份；抗剥落剂0.1～1份。及上述桥面高韧超薄磨耗层的施工方法。与现有技术相比，本发明提供的混合料配比结合对应施工方法形成的桥面高韧超薄磨耗层具有优良的黏结力、抗水抗剥落性能和耐老化性能，能够有效提高行车的安全性和舒适性。
