摘　　要：大跨径钢桥桥面铺装层在正常工作状态下始终与桥面钢板紧密联系,共同承担荷载和变形,两者相互影响,相互制约。因此只有以铺装层和钢板整体为研究对象,才能更准确地反映环氧沥青混合料桥面铺装的实际疲劳性能。In normal work state, the bridge surface pave-load layer of long span steel surface armor plate each other. If put fatigue performance tightly all the times, they take on load and transmutation together, bridge contact effect and re the pave-load layer and the whole armor plate as study object, the actual pave- of epoxy asphalt mixture bridge surface will be reflected accurately.
