This proposed research will consist of a comparative evaluation of the effectiveness of three bridge deck sealers to resist the intrusion of moisture and waterborne chemicals into concrete bridge decks. The Maintenance Bureau of the Alabama Department of Transportation (ALDOT) currently relies on a penetrating epoxy sealer (Spec.Seal) 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 be discontinued. The researchers propose to compare the effectiveness of Spec.Seal against that of two potential replacement products.
