"I was very pleased with the paving work performed. You did a nice job transitioning from the "cut and remove" to the overlay sections. Sunland was very open to comments, questions and suggestions. It was a pleasure working with you."
Overlays
Asphalt Overlay
An asphalt overlay is simply the process of installing a new layer of hot mix asphalt directly over existing asphalt on either parking lots or roads. In order to be a candidate for overlay, a pavement should be relatively sound without large areas of base failure. Prior to overlay, pavement repairs and transitions must be made. Cracks should be filled with rubberized crack sealer, and a tack coat applied over the entire surface. A new layer of asphalt is then placed.
An asphalt overlay is the least costly of the reconstruction techniques, but it has definite drawbacks. These include a limited service life, elevation considerations, inability to make drainage corrections, and a tendency to show reflective cracking in a relatively short period of time.
Fabric Overlay
Fabric overlay is a way to delay reflective cracking, although it will not prevent such cracking. Prior to placing a new layer of hot mix asphalt, a geo-textile fabric is embedded in liquid asphalt binder over the entire surface. The fabric/binder combination forms a membrane that helps keep water out of the base. The cost is approximately one-third greater than a basic overlay.
