Prestressing of bridges allows construction of long spanned bridges made from thin structural members with high flexural and shear capacity. Studies have shown that some of the existing prestressed bridges are not meeting their designed service life due to corrosion of the tendons. The main reasons are poor construction practices in combination with inadequate inspection and maintenance plans. This paper provides a summary of repair options for corrosion-damaged prestressed concrete structures with focus on the individual components of the prestressed system. The applicability of identified repair options to Norwegian conditions is discussed.
