Winner: Concrete Overlay

This multi-year project featured a comprehensive series of concrete overlays constructed between April 2020 and July 2024, totaling more than 3,200 cubic yards of concrete. The initial phase consisted of an unreinforced 4,000-psi concrete overlay placed directly over the existing asphalt pavement.

To manage budgeting and minimize operational disruption, the owner elected to proceed with additional phases annually. Beginning in the second phase, the owner incorporated fiber reinforcement and, by the third phase, transitioned to a 5,000-psi exterior concrete mix, following contractor recommendations and adjustments related to the use of Type 1L cement.

In total, more than 200,000 of the 230,000 square feet of new pavement were successfully installed as overlays on existing asphalt— demonstrating the versatility, performance, and sustainability advantages of concrete overlay systems.

Beyond the engineered improvements, the owner valued enhanced aesthetics, significantly improved nighttime lighting, long-term durability, and reduced maintenance associated with concrete.

The project showcases how phased construction, evolving mix designs, and innovative overlay techniques can be combined to provide a high-performance pavement solution with exceptional lifecycle value.
