Abstract

<p>To solve the serious problem for durability of weathering steel bridges by the undesired corrosion, it is necessary to eliminate its cause or to apply the repair coating. The life expectancy of the repair coating depends on appropriate surface preparation and the reliable removal of rust containing salinity. In this study, two type methods were examined for actual weathering steel bridge in 2015. One of the repair coating method is Rc-I for weathering steel bridges ("washing method") having water washing process, and the others ("water wash less method") have new alternative process that is not washed with water. The investigation of three yers after repair coating showed that both repair coating film was confirmed to exhibit good corrosion resistance.</p>
