Asphalt Overlay

An asphalt overlay is a process of laying a new layer of asphalt on top of an existing pavement surface. This process is typically used to restore or improve the texture of an aging or deteriorating pavement that has suffered from cracking, rutting, or other forms of wear and tear.

To begin the process of an asphalt overlay, the existing pavement surface is cleaned, and any necessary repairs are made. This may involve filling in cracks or potholes, as well as leveling the surface of the pavement. The new asphalt layer is then applied, typically between one and three inches in thickness, depending on the condition of the existing pavement.

The new asphalt is spread evenly across the surface of the existing pavement and then compacted with a roller to ensure proper adhesion and a smooth surface. Once the overlay is complete, pavement markings and other features, such as crosswalks or signage, are added as needed.

An asphalt overlay is generally less expensive than a complete pavement replacement, making it a cost-effective solution for extending the life of a pavement surface. It can also be completed relatively quickly, minimizing disruption to traffic and other activities in the area.

However, an asphalt overlay may not be appropriate in all situations. For example, a complete replacement may be necessary if the underlying pavement structure is severely damaged or the existing surface is too uneven. Additionally, if drainage or other issues are not addressed before the overlay, they may continue to cause problems and shorten the lifespan of the new surface.
