Abstract:Precast double-tee girders are common on county bridges in South Dakota (SD) because of the ease of construction, the short construction time, and the low cost. However, the longitudinal joints of these bridges are rapidly deteriorating, imposing girder replacement after only 45 years of service. Currently, there are more than 700 double-tee bridges in SD incorporating this joint detailing. The present study was conducted to develop, construct, and evaluate rehabilitation methods for this type of bridge.
