Performance Evaluation of Crack and Deck Sealants for Concrete Bridge Decks

Bridge Decks
Corrosion of steel reinforcement from salt intrusion can greatly reduce the service life of a concrete bridge deck. Sealants applied to the deck surface and within cracks can reduce this corrosion. Sealant product performance is tested with electrically wired macrocells that are exposed to saline solution for long-term intervals. Specimens are opened, visually inspected, and compared to evaluate performance.
