63 5.1 Summary of Findings This research effort produced recommended design and material guide specifications for the design of concrete beams prestressed with CFRP systems for bridge applications. These design and material guide specifications were provided to the AASHTO Committee on Bridges and Structures.

Summary of Findings and Recommendations for Future Research 65 material types and their use with harped CFRP cables or bars will be helpful. In addition, use of the prestressing CFRP systems with deviated or harped profiles in pre-tensioned or external post-tensioned beams needs to evaluated in experimental and analytical investigation of the flexural behavior of the CFRP prestressed beams with harped strand profiles.
