Abstract: Repairing damaged concrete by mortar overlay method have been generally applying as repair method for deteriorated Prestressed Concrete (Here in after called PC) railway bridge by salt contamination. However deterioration of concrete occur again in short time. Then, we
have tried to extend service life of salt contaminated bridge by application of cathodic protection system, because we found that cathodic protection system have a possibility to reduce cycle cost compared with mortar overlay method. Therefore, We have decided to verify the effectiveness and cost of cathodic protection system among selected five cathodic protection system.
