Rehabilitation of Longitudinal Joints in Double-Tee Bridge Girders

Currently, there are hundreds of double tee bridges on South Dakota highways that were built using the standard joint detailing. Based on observed field performance and test results, those bridges may be deteriorating at a fast rate and their useful lifespan may be much shorter than the expected 50 - 75 years. While new bridges can be built using the proposed joint detailing developed under project SD2013-01, replacing the currently existing deficient bridges would be cost-prohibitive. Therefore, a cost-effective retrofit to upgrade the joints of existing bridges would be an attractive alternative to replacing deficient bridges and extending the life span of existing bridges.
