FURTHER IMPROVEMENTS IN CATHODIC PROTECTION. FINAL REPORT
The performance of seven cathodic protection systems installed on two mild steel reinforced concrete bridges was assessed. One bridge is located in a marine environment and the other is located in a northern climatic region. Critical review of embedded silver/silver chloride reference cells and macrocell rebar probes was made. Constant voltage and constant current control for cathodic protection systems were monitored and results are described. Test procedures and actual field data to establish cathodic protection criteria for bridge structures are discussed. The effectiveness of an improved coke-asphalt cathodic protection system for bridge decks was laboratory tested and discussed.
