Repair Methods for Prestressed Girder Bridges
What’s the Problem: Prestressed concrete bridges are exhibiting signs of
deterioration and distress Although there are many research/case studies
addressing repair of prestressed girder bridges, there is little comprehensive guidance available to bridge engineers
