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。
The waterproof adhesive layer is an important structural layer to ensure the durability of the deck pavement structure. Based on the self-developed layer shear equipment, this test system forms a set of performance evaluation system based on the interlaminar shear test. Designed to choose than the performance of the adhesive layer. Through orthogonal test, the shear strength of the four kinds of waterproof adhesive layer under the influence factors of different pre-pressures under different temperatures was compared and analyzed. Finally, the fiber reinforced rubber asphalt waterproof adhesive layer has the best bonding strength and road performance, Surface pavement engineering design and construction to provide reference.
