摘要
针对桥面铺装结构较厚,且容易出现病害等问题,对桥面铺装材料力学性能进行分析,提出了一种桥面环氧薄层结构,并进行了防滑薄层弹性环氧胶黏剂的开发.通过对增韧剂、稀释剂和固化剂的研究、选择及配方优化,制得了一种性能良好的防滑薄层弹性环氧胶黏剂.通过拉伸测试可知,其拉伸强度可达21MPa,断裂伸长率达50%.同时其与混凝土粘接强度可达2.5MPa,且热相容性通过.试验结果表明,桥面防滑薄层弹性环氧胶黏剂综合性能优异,适用于桥面铺装工程.
To address the problem of the thick pavement structure and the damage of the bridge deck, this paper analysed the mechanical properties of the bridge deck pavement material, proposed a kind of thin epoxy overlay struc- ture and developed elastic epoxy resin adhesive. Through the selection and formulation optimization of flexibilizer, dil- uent and curing agent, a kind of elastic epoxy resin adhesive with good performance was obtained. Tensile testing has shown that the tensile strength of the elastic adhesive is 21 MPa, and the elongation is 50%. Meanwhile, its bond strength is up to 2. 5 MPa and the thermal compatibility is appropriate. The results have also shown that the compre- hensive performance of the elastic epoxy resin adhesive is excellent, and it can be applied to bridge deck pavement en- gineering.
