Evaluation of Maintenance Procedures for Bridge Spalling on Parapet Walls - Phase 2

Ohio Department of Transportation (ODOT) county maintenance forces are responsible for removing unsound concrete (spalling) on parapet walls and deck edges from bridges over traffic. The work entails setting up extensive traffic control zones followed by removing the unsound concrete with small pneumatic jack hammers. Once the unsound concrete has been removed a new surface area has been created that is left unprotected from the deicing materials used during the snow and ice season. The purpose of this research is to determine if there is a better way to remove the unsound concrete in lieu of pneumatic tools, the extent of removing unsound concrete before jeopardizing the safety of the bridge, and the best method to seal/protect the newly exposed concrete surface to prevent further deterioration. Phase 1 of this research conducted an in depth analysis of ODOT's current process for repairing spalling on bridge parapets and deck edges and provided recommendations on how to improve safety, production and cost effectiveness. Phase 2 is to determine the feasibility and cost effectiveness of implementing the recommendations from Phase 1.
