Repair and Maintenance of Post-Tensioned Concrete Bridges
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.
