Concrete Overlay

This set of photos presents rubblization with concrete overlays. Although rubblized concrete is almost always overlaid with asphalt, Antigo has completed several highway projects, and more commonly airport projects, where the overlay was constructed with concrete pavement. An interlayer of crushed stone is usually placed on the rubblized concrete for crown correction and to provide a very uniform surface that can be trimmed prior to the concrete paving operation.
