Abstract:The Arthur Laing Bridge was constructed in 1975. At a relatively early age of about 6 years it began to suffer damage due to corrosion of the deck reinforcement. A major rehabilitation and resurfacing program was implemented in 1987, which included the installation of a cathodic protection system on about 45 percent of the 21,200 mý deck. This is one of the largest installations of cathodic protection on a reinforced concrete bridge deck. The original deck was milled to a depth of 15 to 25 mm to remove chloride-contaminated concrete. A catalyzed titanium wire mesh anode system was installed on the milled surface after delaminations had been patched. Finally a 50 mm thick low-slump dense concrete overlay was placed. This paper describes the design and construction of the cathodic protection system. Technical details of the cathodic protection and overlay system and construction costs are also presented.
