BRIDGE DECK EXPANSION JOINTS

The ability of a bridge deck expansion joint to be smooth riding, durable, and waterproof is essential to the performance of the bridge superstructure. Recent developments in the design, manufacture, and installation procedures for expansion dam systems have indicated a potential ability to meet these requirements. In this study, the characteristics and field performance of modular expansion joint systems, metal-reinforced elastomeric expansion dam systems, and gland-type bridge expansion dam systems were evaluated. Results of the field study are summarized and recommendations made on continued use of some systems, including neoprene seals for small movements (less than 2 in.), strip seals for intermediate movements (up to 4 in.), and finger dams with neoprene troughs for large movements (greater than 4 in.).
