橡胶沥青砂胶在混凝土桥面铺装中的应用

Application of Rubber Asphalt Sand Gel in Concrete Bridge Deck Laying

橡胶沥青砂胶是西部交通科技项目“桥面铺装材料与技术研究”在混凝土桥面铺装方面的一项研究成果。通过不同粘接材料的粘接强度测试比较和橡胶沥青砂胶在混凝土表面上抗剪切强度试验,确定其在混凝土表面的抗剪切强度高,并且由于其施工工艺对桥面板平整度状态的适应性较强,因而适合在水泥混凝土桥梁沥青桥面铺装中应用。

Rubber asphalt sand gel is a science achievement of Western China communications science ＆ technology project ＂Bridge deck laying material and technical research＂ regarding concrete bridge deck laying. Through anti sheafing strength test and comparison among different binding material and anti - sheafing strength test of rubber asphalt sand gel on surface of concrete, it is proven that it has high anti - shearing strength on concrete surface, and because of strong accommodation of its process to bridge deck levelness, it is suit for application in cement concrete bridge asphalt bridge deck laying.
