CATHODIC PROTECTION OF BRIDGE SUBSTRUCTURES: BURLINGTON BAY SKYWAY TEST SITE, DESIGN AND CONSTRUCTION PHASES

The design and construction phases of a research program to develop an effective cathodic protection system for use on bridge substructures are described. Construction of four experimental systems on columns of the Burlington Bay Skyway Bridge was completed in 1982. One sacrificial anode system and three impressed-current systems were installed, each covering approximately 38 m2 of column surface. The sacrificial anode system used zinc ribbon anodes with a shotcrete overcoat. A conductive polymer concrete was used as the primary anode in all the impressed-current systems. In System 1 the anodes were used with a shotcrete overcoat. System 2 consisted of the primary anodes with an exposed secondary anode of conductive paint. System 3 employed a secondary anode network of multifilament carbon strand, also with a shotcrete overcoat. A range of instrumentation was designed and installed to determine the effectiveness and efficiency of the four systems.
