Many long span steel bridges were built in China, for which epoxy asphalt was used as the deck pavement. Due to the extreme conditions including high traffic volume and high temperature, early damages often happened in many steel deck epoxy asphalt pavements. This paper based on the performance of cold mix resin material deals with the preventive maintenance technology, the remedial method of typical damage and the medium and major maintenance technology over the whole life cycle of epoxy asphalt steel deck pavement . The mechanical properties of the structure and the material properties of each technology were studied respectively. And they have been successfully applied in the maintenance of Runyang Bridge. The research results in this paper will be a reference to the maintenance of long span steel deck epoxy asphalt pavement and it has higher value in application.
