AASHTO TF-29, Guide Specification for Cathodic Protection of Concrete Bridge Decks (1994), was issued by the task force formed to address corrosion of reinforcing steel in bridge decks. The guide describes the cathodic protection systems available for deck protection, the design considerations that govern their selection, installation requirements and the monitoring needed to confirm that the system is working. It is intended for bridge designers and maintenance engineers dealing with chloride-induced corrosion in existing decks rather than for new construction alone.
