• Abstract:
  Fiber- reinforced polymer composites (FRP) are an attractive repair option for existing concrete structures. CDOT has used this material on some projects, in particular the repair of the Castlewood Canyon Bridge in 2003. Further use of the material is limited by the lack of data about its long-term performance. Laboratory durability studies have indicated that FRP performs well in conditions such as water and salt water baths, but it is difficult to fully capture field environments in the lab. This project evaluated the condition of the FRP on the Castlewood Canyon Bridge through onsite inspection and pull-off tests, and by bringing FRP back to the labs at CSU to test the tensile strength. Conclusions about the FRP condition are limited by the lack of baseline data, but there does appear to be some deterioration over time. This project also considers the influence of deicing agents on FRP properties through laboratory testing that has been initiated.
