CONCRETE BRIDGE DECK PERFORMANCE

This synthesis report provides information on previous and current design and construction practices used to improve the performance of bridge decks. The primary focus is on North American practice for cast-in-place (full depth and partial depth), reinforced concrete bridge decks on steel beams, concrete I- and T-beams, or concrete box beams. Information was obtained on the following topics: factors that contribute to the durability of concrete bridge decks; performance of various types of deck protection strategies; lessons learned and the current state of the practice in design, construction, and maintenance of concrete bridge decks; available comparative analysis of the effects of using different methods and materials; specific reports of successes and failures; sample design and construction specifications; available life-cycle cost information; research in progress; and suggestions for future study. This synthesis report combines information obtained from survey responses from bridge owners and from a literature review.
