NCHRP Synthesis 20-05/Topic 15-02 [Final (Synthesis)]

Durability of Prestressed Concrete Highway Structures
[ NCHRP 20-05 (Synthesis of Information Related to Highway Practices) ]

  Project Data

This synthesis will be of interest to bridge designers, materials engineers, maintenance engineers, and others concerned with the durability of prestressed concrete bridges. Information is presented on the factors affecting the durability of prestressed concrete. Prestressed concrete bridges require special attention because the capacity of the structure is strongly dependent on the prestressing force. This report of the Transportation Research Board reviews the factors affecting the durability of prestressed bridge components and describes methods of detecting and assessing deterioration, preventive maintenance, repair, and methods of improving durability in new structures.  The report for this topic can be purchased at http://www.trb.org/news/blurb_detail.asp?id=3417
