The use of post-tensioning in concrete structures has allowed for the construction of economical long-span bridges. However, very limited information is available to guide bridge owners on how to maintain existing structures or, more specifically, to repair degraded post-tensioned structures.

The TRB National Cooperative Highway Research Program's NCHRP Synthesis 562: Repair and Maintenance of Post-Tensioned Concrete Bridges gathers information on the practices used by bridge owners to repair and maintain post-tensioned bridges and facilitates knowledge transfer across state departments of transportation (DOTs), aiding bridge owners in the identification of repair practices that are working and that will extend the useful life of the bridges.

Supplemental materials to the report include appendices containing the survey and the survey responses.
