Concrete bridge deck performance.

This synthesis report provides information on previous and current design and construction practices that have been used to improve the performance of concrete bridge decks. North American practices for cast-in-place (full and partial depth), reinforced concrete bridge decks on steel beams, concrete I- and T-beams, and concrete box beams are the primary focus. To accomplish this study, information was obtained from a survey distributed to highway agencies in the United States and Canada and a review of the literature. The report includes information on the effects of concrete constituent materials and concrete mix pro-portions on the durability of concrete and its effectiveness in protecting steel reinforcement from corrosion, summarizes systems that have been used as alternatives to noncoated steel reinforcement, discusses barrier systems designed to protect primary concrete and reinforcement from deterioration, provides information about design and construction practices related to bridge deck performance, and discusses cracking of concrete bridge decks.
