Description: Some states are replacing deteriorated bridge decks with full-depth prefabricated decks to accelerate onsite construction and minimize traffic impacts. Because prefabricated decks are typically erected as segments that must be joined together, the connections are the critical factor for ensuring good long-term performance and achieving an economical solution. This presentation describes design, construction, and maintenance details that have been developed to achieve good long-term performance of full-depth prefabricated bridge decks. Comparisons are made between some of the various details considered for a project in Oregon, with advantages and disadvantages that were identified for each.
