When interconnected asphalt cracks in your parking lot begin appearing, it's time to begin thinking of a repair or maintenance solution. The problem is that when the asphalt starts cracking and is left unrepaired, water settles into those cracks, they expand, and eventually required reparations become extensive. Caught in time, however, typical asphalt crack repairs can be as simple as a sealcoating job or a basic asphalt resurfacing, or overlay.
This is a terrific option on larger parking lots where function is the main goal and cost is an issue. In most cases this option can add 10+ years to the life of a parking lot for a fraction of the cost of full replacement. The downside of this application is that “reflective cracking” will occur, meaning that if there was a crack in the surface underneath it will typically show in the new surface within a few years. The biggest limitation of this option is often drainage, so it is important to have an experienced professional examine the site to determine if an overlay will be a viable option.
typically range from 1.5″ to 2″
often require a small amount of “skim patching” in order to level out any uneven surfaces prior to application of the overlay
often require the removal of some of the old asphalt to allow a new layer to be added and still maintain an even transition at garage floors, sidewalks, aprons, etc…
What is an overlay? An overlay is the resurfacing of existing pavement. Existing asphalt or concrete pavements can be overlaid with hot mix asphalt with excellent results. Before paving, existing pavement should be checked for any repairs needed, cleaned of all loose debris and tacked for successful adhesion.
What is an overlay and is it appropriate for my needs?
A: On some occasions, it is possible to apply a new layer of asphalt over an old layer. The salesperson would need to inspect the site to make that determination. Unfortunately, overlays are often done on pavements that should have been removed. Wolf Paving will only overlay where conditions warrant.
Why is a tack coat needed? A tack coat is used on an overlay/resurface project, it is used to form a bond between an existing surface and the overlying course.
