Concrete Overlays - Concrete Parking
Over the past 30 years, overlays of 4-20 inches have yielded exceptional results in the rehabilitation of asphalt parking areas, streets, highways, and airport runways. In the late 1980s, researchers developed ultra-thin overlays by reducing the thickness, reinforcing the material, and redefining the joint spacings of standard overlays.
