As opposed to mix and mill, which recycles the asphalt surface and the base layer, asphalt overlay is the placement of hot mix asphalt over existing asphalt. This type of rejuvenation typically starts with an asphalt emulsion tack coat to ensure proper bonding of the old asphalt layer to the new one and then applying the new layer of asphalt on top of the old. As soon as the freshly laid hot asphalt mix is compacted and begins to cool, the curing process begins and the new pavement becomes firm. Depending on the condition of the underlying asphalt this application can cost 2-3 times less than removal and replacement of the existing pavement. It is important to address any deterioration to the paving surface before it’s too late. A maintenance and care programme can add years to your asphalt surface.
