Development of Simple Bridge Deck Details at Expansion Joints, Project Summary
The Texas Department of Transportation (TxDOT) has, in recent decades, dedicated considerable resources to improving bridge construction methods. Evolving from this effort is the current practice of using prestressed concrete panels in bridge decks. The use of these panels eliminates the majority of formwork for concrete bridge decks, decreases construction time, and reduces construction costs. Skewed expansion joints in bridge decks present a unique challenge for precast panel bridge deck systems. Precast (PC) panels are generally rectangular in shape and leave trapezoid-shaped gaps at the end of the deck adjacent to the expansion joint. Current bridge construction practices call for the use of stay-in-place sheet metal forms or timber forming methods to construct the IBTS detail at the end of the bridge deck.
