桥面防水粘结层对保证桥面铺装质量及提高桥梁耐久性具有重要意义,当前桥面防水材料种类繁多,但施工质量和长期使用效果难以保证。结合工程常用的喷涂型防水粘结材料和水性环氧沥青材料,测试各种粘结材料在不同成型方式和不同温度条件下的力学性能,横向比较以及衡量材料能否适应工程实际需要的基本要求,并结合工程现场施工的要求,提出桥面防水粘结层的粘结及抗剪切强度现场检验要求。
Bridge waterproof adhesive layer to ensure the quality of the bridge deck pavement and improve the durability of the bridge is of great significance, the current bridge deck a wide range of waterproof materials, but the construction quality and long-term use of results is difficult to guarantee. Combined with the commonly used engineering water-based spray-bonded waterproofing materials and water-based epoxy asphalt materials, various bonding materials tested in different molding methods and different temperature conditions, mechanical properties, horizontal comparison and to measure the material can adapt to the actual needs of engineering basic requirements , Combined with the requirements of the construction site engineering, put forward the bridge deck waterproof bonding layer and shear strength on-site inspection requirements.
