Arkansas I-440 Bridge Pier Strengthening
The Arkansas I-440 bridge spanning the Arkansas River was experiencing repeated cracking throughout several concrete piers. Traditional repair methods often involve short-term crack injections that require additional maintenance in the near future, leading to substantial additional costs as the years go on. Arkansas DOT was looking for a valued engineering alternative to provide more of a lasting repair.
Fibrwrap Construction was contacted to inject over 40,000 square feet of cracks with epoxy. Fyfe Company, LLC’s glass-based Tyfo® SEH-51A composite system was then used to wrap the pier columns and caps to provide additional strength and protection from exposure to corrosive environments.
The low weight and high tensile strength of the glass composite system provided an excellent long term solution to the piers while mitigating any future crack growth. The piers were finished with a UV protective coating that best matched the color of the existing structure.
