【摘要】：防水黏结层是确保桥面铺装结构耐久性的重要结构层,本试验研究依托自主研发的层间剪切设备,形成一套基于层间剪切试验的桥面防水黏结层的性能评价体系,旨在比选出性能优异的黏结层。通过正交试验,对比分析4种防水黏结层在不同温度不同预压力的影响因素下的剪切强度,最终发现纤维增强的橡胶沥青防水黏结层具有最优的黏结强度及路用性能,为桥面铺装工程设计及施工提供借鉴。
[Abstract]:Waterproofing bonding layer is an important structure layer to ensure the durability of bridge deck pavement structure. This test study is based on self-developed interlayer shear equipment to form a performance evaluation system of bridge deck waterproof adhesive layer based on interlayer shear test. The bonding layer is designed to be superior to the selection of the bonding layer. Through orthogonal test, the shear strength of four kinds of waterproof adhesive layers under different temperature and different prepressure was compared and analyzed. Finally, it was found that the fiber reinforced rubber asphalt waterproof adhesive layer had the best adhesion strength and road performance. It provides reference for bridge deck pavement engineering design and construction.
