Arkansas I-440 Bridge Repair

Several concrete piers supporting the Arkansas I-440 bridge were found to be experiencing repeated cracking. Traditional repair methods often involve short-term crack injections that require additional maintenance. The Arkansas DOT was looking for a robust alternative to provide a lasting repair.

To resolve the issue a contractor injected more than 40,000 square feet of cracks with epoxy. FRP 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 a 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.
