Durability of Prestressed Bridge Decks
The report briefly presents background information on the mechanism of corrosion of steel reinforcement in concrete, and summarizes the observations and findings from an experimental corrosion study. A simple test specimen was developed to simulate the behavior of a transversely prestressed bridge deck subjected to an aggressive deicing salt exposure. The experimental program investigated the primary variables affecting corrosion of steel in prestressed concrete: concrete cover, crack width, protective coatings for steel reinforcement, type of prestressing protective system, concrete quality, and level of prestressing. Behavioral trends are presented as determined from half cell potential measurement of the nonprestressed reinforcement, chloride analysis of the concrete, and visual observation from a post mortem autopsy of the specimens.
