摘　　要：以南京市七里河桥钢桥面铺装为实例,介绍了抗滑耐久型环氧沥青EA+ESMA铺装技术要求、防水黏结层及黏层施工、混合料拌和—运输—摊铺—碾压—养生等工艺,并进行了工后路面的渗水系数、构造深度等指标检测。抗滑耐久型环氧沥青EA+ESMA铺装在七里河桥钢桥面铺装工程中的应用情况良好,混合料及路面的各项性能指标均满足要求,铺装施工质量较好,可为类似工程提供参考。Using the steel bridge deck pavement of Qilihe Bridge in Nanjing as an example,this paper details the technical requirements for anti-skid and durable epoxy asphalt EA+ESMA pavement,including waterproof bonding layer and bonding layer construction,as well as the processes of mixture preparation,transportation,paving,rolling,and curing.Post-construction tests measured the water permeability coefficient and structural depth,among other indicators.The application of anti slip and durable epoxy asphalt EA+ESMA pavement in the steel bridge deck pavement project of Qilihe Bridge has shown positive results,and the performance indicators of the mixture and pavement meet the requirements.The quality of the pavement construction was high,making it a useful reference for similar projects.
