The Long-Term Performance Of Concrete Crack And Deck Surface Sealers, Emily A. Byl

Open Access Theses

Concrete bridge decks in the State of Indiana are undergoing continuous deterioration and loss of service life due to the use of deicing salts during winter weather conditions. As salt water penetrates the deck through cracks and the concrete surface, chlorides, water and oxygen are able to access the reinforcement to initiate corrosion. The corrosion of reinforcing steel over time creates an ongoing need for costly deck repairs and/or deck replacement. This study investigates the performance of crack sealers and deck surface sealers as a potentially cost-effective method of increasing bridge deck service life. An experimental program was developed and …
