Asphalt Overlays – Resurfacing
Asphalt overlays are also commonly referred to as resurfacing or putting a ‘cap’ on your existing asphalt. Although not always possible, overlays are a major cost saving alternative to removing and replacing the existing asphalt. If the existing asphalt is not too badly deteriorated we are able to resurface the existing asphalt with a new layer of asphalt.
Depending on the condition and thickness of the existing asphalt we may mill (grind) off a thin layer of the old asphalt to create a uniform surface for the asphalt overlay. Usually a one to three foot section will be removed wherever new asphalt will meet existing asphalt or concrete in order to assure a smooth transition. A layer of liquid asphalt called tack coat, which functions as a bonding agent, will be sprayed on the existing asphalt before the new asphalt is applied. Tack coat is extremely ‘tacky’ or sticky and assures that the new asphalt will bond properly with the old asphalt.
Although asphalt resurfacing will undoubtedly improve the appearance of your lot or roadway, asphalt overlays will also correct drainage problems and safety concerns.
Parking Lot Repair
Potholes and cracks don’t just look bad, they increase the risk of vehicle damage and injuries. Proper repair and maintenance of parking lots is essential to preserve property values and to alleviate safety concerns.
If there is extensive damage to the asphalt surface such as potholes, large cracks, or extensive cracking and crumbling, an overlay may be required. In some cases even an overlay may not be enough to correct the problems, especially if there are issues with the base material under the asphalt. When the base is no longer strong and stable the entire lot may need to be removed and replaced.
Our experts will assess the condition of your parking lot and make a recommendation on the best way to correct the problems. If the lot can be repaired through patching, we will cut out the damaged areas, add additional stone where necessary, and install and compact new asphalt in the cut out areas. We will apply hot rubberized crack sealer to the edges of the patch to seal the new asphalt with the existing asphalt.
Small potholes can often be repaired without the need for cutting out the area simply by cleaning out the potholes, applying tack coat, and applying two to three inches of compacted asphalt.
