摘要
环氧沥青较普通热塑性沥青具有更优越的物理性能和化学性能,如高强度、强粘接性能、优良的抗疲劳性能、良好的耐久性及抗老化性能等,因此在特种公路和大型桥梁得到了广泛的应用。对道桥用环氧沥青的制备方法及研究进展作了比较全面的综述,介绍了分别采用共溶剂、改性沥青、特殊的环氧树脂和改性固化剂等工艺,并对这些方法有关的机理以及结果等进行了讨论。
Epoxy bitumen had been used in special roads and big bridges for their superior properties （physical and chemical） for common thermoplastic bitumen, such as excellent strength, adhesion, service durability, ageing resistance and so on. This review mainly described the research trends of the preparation methods of epoxy bitumen which used for road and bridge deck, and introduced the technologies of the co - solubilizers method, modified bitumen method, using special epoxy method and modified curing agent method. We also discussed the principle and results of these methods.
