Project description

This project consists of a comparative evaluation of the effectiveness of 3 bridge deck sealers to resist the intrusion of moisture & waterborne chemicals into concrete bridge decks. The Maintenance Bureau of ALDOT currently relies on a penetrating epoxy sealer (SpecSeal) that is manufactured solely for ALDOT. It is critical to identify a potential replacement product of equal or greater effectiveness, should production of the currently-used sealer.
