摘要
针对环氧沥青钢桥面铺装材料,通过借助MMLS3加速加载试验方法,分析了大跨径钢桥面环氧沥青铺装面层、粘结层与钢箱梁底层受力变形与加载次数的变化规律.试验结果表明:环氧沥青铺装各结构层动载变形分布范围稳定.在长期循环荷载作用下,其抗疲劳性能优异.
For the epoxy asphalt of steel deck pavement materials,through the use of MMLS3 accelerated loading test method,the variation of force deformation and load times for the epoxy asphalt pavement surface layer,adhesive layer and steel box girder underlying of large-span steel bridge were analysed.The results show that the dynamic deformation of the epoxy asphalt pavement structure layer distributes stability.In the long-term cyclic loading,it has an excellent anti-fatigue property.
