CATHODIC PROTECTION OF TAY ROAD BRIDGE SUBSTRUCTURE

Structural surveys of the reinforced concrete marine substructure of the Tay Road Bridge indicated that widespread corrosion of reinforcement had occurred within the splash zone as a result of chloride attack from the surrounding seawater. A review of repair options applicable to such areas was carried out and it was concluded that cathodic protection was potentially the most effective means of controlling corrosion over extended periods. A cathodic protection system has been developed through a number of trial installation and material assessments carried out between 1986 and 1989. These trials are described with particular attention being focused on the performance requirements of cemetitious overlay materials for distributed anode systems. (Author/TRRL)
