| 摘要： | The report describes the application and testing of two separately installed metallized zinc cathodic protection (CP) systems: one applied to the deck and the other to the soffit of a reinforced concrete bridge that had been contaminated from deicing salt use on the top surface. Both installations are impressed current systems. The deck system was installed by state forces and the soffit system was installed by contract. Documentation includes the CP designs, application parameters, and 3.6 years of field monitoring to determine the effectiveness of each system. The systems have been operating since November 1985. Several successive years of below average precipitation during the study period, and the application of a slurry seal and a chipseal coat to the bridge deck CP system, affected the operation and ability to monitor both the deck and soffit CP system. |
