水泥混凝土桥面防水粘结材料性能试验研究

Experimental Study of Cement Concrete Deck Waterproof Binding Material Performance

现阶段江苏省高速公路桥面铺装一般为沥青结构,故水泥混凝土桥面与沥青混凝土结构层中间防水粘结层的设置对于水泥混凝土结构和沥青混凝土桥面使用寿命至关重要。该文对三种防水粘结材料的原材料性能进行检验,室内模拟了三者的实际路用性能并进行对比分析,现场检测了防水粘结层的拉拔强度和剪切强度,为合理选择防水粘结材料提供了依据。

The deck pavement of the expressways in Jiangsu Province at the present stage is generally asphalt structure. Therefore,the arrangement of the waterproof binding coat between the cement concrete deck and the asphalt concrete structure course is the most important to the service life of the cement concrete structure and the asphalt concrete deck. The article carries out the inspection of the raw material performances of three waterproof binding materials. The practical road performances of three materials are simulated indoor and compared and analyzed. The pull strength and the shear strength of the waterproof binding coat are detected in site,which provides the basis for reasonably to select the waterproof binding materials.
