EARLY PERFORMANCE OF EIGHT EXPERIMENTAL CATHODIC PROTECTION SYSTEMS AT THE BURLINGTON BAY SKYWAY TEST SITE
The initial phases of a research program to develop an effective cathodic protection system for use on bridge substructures are described. Four experimental cathodic protection systems were installed on the columns of the Burlington Bay Skyway Bridge in Burlington, Ontario, in 1982 and four more were added in 1983. Seven were impressed-current systems and one was a galvanic system. Each system covered approximately 40 sq m of concrete surface. Several types of instrumentation were developed to monitor the effectiveness of the cathodic protection. All eight systems are being monitored, and the data collected through July 1984 are presented. All the impressed-current systems were found to be effective in stopping corrosion, but the components of some systems were not sufficiently durable. Insufficient power was available from the galvanic system for it to be practical. The future work required to develop a full-scale operational cathodic protection system for bridge substructures is discussed.
