UNDER CONSTRUCTION Concrete overlays are a sustainable strategy to preserve and extend the service life of a pavement. Concrete overlays can be used for preventive maintenance as well as minor and major rehabilitation for asphalt, composite, and concrete pavements. They can be designed for short-term (5-15 years) as well as long-term (20-35 years) applications.
