Synthesis of Bridge Approach Panels Best Practices

Status:  Complete
Report Date:  04/23/2013


Joints between the approach panel and the pavement on integral and semi-integral abutment bridges in Minnesota often fail prematurely due to compression and expansion from the state's wide temperature swings. This project surveyed nearby state and provincial transportation departments to learn their practices for these types of joints. Strip seals, neoprene compression seals from D.S. Brown and Sealtite polyurethane foam are recommended for further consideration in Minnesota.
