The aim of this study is to obtain technical data on durability evaluation method for steel bridge coatings in order to formulate specific safety guidelines for the coatings. We have examined corrosion protection properties and weathering resistance of coating films. Coating system "C-5" which are provided as standard coating systems for Japanese steel highway bridges in the Coating Handbook edited by Japan Road Association have been picked up as experimental objects. The test pieces coated with C-5 system have been subjected to accelerated weathering tests (under xenon-arc radiation) and cyclic corrosion tests (salt fog/dry/humidity). The basic data for C-5 system such as appearance, glossiness, color difference, rust formation, adhesion, and so on have been corrected.
