Abstract
Many weathering steel bridges has been constructed due to its advantage in Life Cycle Cost. With the expansion of number of weathering steel bridges, occurrence of corrosive rust on weathering steel has been reported in recent years. However, repair technique of corroded weathering steel is not established yet. At the time of repair painting, ablation of the adherence rust and the adherent salt on surface of weathering steel will become major problem. This paper propose a flow of repair painting for weathering steel bridges based on Rc-I painting method that was established to painting bridges. By the results of aplication of this flow to on site repair, availability of proposed method was confirmed.
