Long Term Monitoring of Mechanical Properties of FRP Repair Materials

Over the years, Fiber Reinforced Polymer (FRP) composites have gained popularity in transportation infrastructure as a material able to restore and increase the capacity of existing concrete elements. Properties such as a high strength to weight ratio, non-corrosive nature, durability, and high malleability make FRP materials an appealing alternative in the reinforcement of these structural elements. However, there are still concerns regarding the long-term performance of these repairs. Numerous studies have been completed by means of accelerated aging in the lab. However, behavior of these materials under realistic field conditions has yet to be thoroughly researched. As a result, this project was created to assess the durability of an FRP repair in the Castlewood Canyon Bridge in Colorado. In addition, a laboratory study was conducted to determine the long-term behavior of concrete reinforced with FRP when exposed to various environmental conditions. The specific tasks in this project include data collection and testing plans for field assessment, on-site testing and sample collection, laboratory testing and data analysis, and testing program with a focus on the effects of deicers on FRP. Finally, a literature review was developed to consider other concerns that the Colorado Department of Transportation (CDOT) engineers may have on the subject.
