摘要
该文综合分析沥青混凝土桥面铺装早期破坏发生的原因,采用试验设备进行室内剪切试验,考查桥面铺装结构防水粘结层的抗剪性能,分析研究各影响因素对性能指标的影响大小。研究结果表明,从防水粘结材料种类来看,采用橡胶沥青砂胶+溶剂性粘结剂+环氧树脂组合的防水粘结层抗剪强度较好,可以在一定程度上增强防水粘结层的抗剪强度。
The article comprehensively analyzes the early destroying cause of asphalt concrete deck pavement.The experimental equipment is used for the indoor shear test to examine the shear performance of waterproof bonding layer deck pavement,and to analyze and study the influence of various factors on the performance indexes.The results show that the shear strength of the used waterproof bonding layer composed of rubber asphalt sand mastic + solvent adhesive + epoxy resin is better and is able to increase the shear strength of waterproof bonding layer to some extent after the comparison of various waterproof bonding materials.
