Abstract:
Alternative reinforcement such as Glass Fiber Reinforced Polymer (GFRP) and Basalt (BFRP) are gaining
popularity due to their corrosion resistant properties in extremely aggressive environments. The Florida Department
of Transportation was concerned with the long-term durability of fiber resin systems in wet marine environments and
restricted its use in submerged marine locations. This paper demonstrates the implementation of a pilot project after
the thorough evaluation of a Fiber Reinforced Polymer resin prior to broader deployment of the alternative
reinforcement. The paper focuses on the successful construction implementation to provide an archival reference
document for future study and comparison to look at the long-term performance and integrity of the strengthening
systems. During the execution of this pilot project, several lessons were learned and are demonstrated in this paper.
