摘要
大跨径钢桥桥面铺装层的使用条件和受力状态十分恶劣,对铺装层材料要求非常高。环氧沥青混凝土具有很高的强度、优良的耐疲劳和耐腐蚀性能,优良的高温稳定性和水稳定性,并且在低温条件下的收缩系数与钢板相近,导致其温度应力大幅度的降低。因此,环氧沥青混凝土适合用作大跨度钢桥桥面铺装材料。
The mechanical and application condition of pavement on long span steel bridge deck is so hard that the paving material is of high requirement. The epoxy asphalt is proved of high strength, perfect anti fatigue and anti erosion performance, and excellent stabilities against high temperature and water erosion. And it can decrease the thermal stress to a large extent. At low temperature, since its shrinking coefficient is simi lar to that of the steel plate, Therefore, the epoxy asphalt is fit for the paving material on long span steel bridge deck and of great value in the application in future.
