Asphalt has become the leading paving material for highways, parking lots, and city streets over the last century. Asphalt pavements are cost-effective, durable, and attractive, and they deliver outstanding performance. Asphalt pavements can last for many years with an effective pavement management plan to ensure timely and proper maintenance.
Every asphalt pavement needs periodic maintenance to mitigate the effects of time, the environment, traffic, and chemicals. Left unchecked, these influences can inflict damage that can lead to the premature deterioration of the pavement. Repair costs can skyrocket, and it may be necessary to have the entire pavement removed and replaced. Professional attention, including periodic inspections, pothole repairs, crack sealing, sealcoating, and resurfacing, can help keep costs down while providing a longer, more attractive life for your asphalt pavement.
Asphalt resurfacing is the placement of a new layer of asphalt over the top of an existing pavement. Resurfacing is typically performed when the pavement is nearing the end of its useful life and has a relatively intact base but large sections of surface damage. Although an overlay can have the life and appearance of new pavement, resurfacing will usually cost much less than complete removal and replacement.
Resurfacing involves cleaning and preparing the surface, and it may be necessary to repair or patch damaged areas prior to installing the overlay. Asphalt patching is commonly used to correct small areas of alligatored pavement or to repair potholes. Patching involves saw-cutting and removing the affected area, repaving with a hot mix asphalt, and compacting the area properly.
Prior to resurfacing, it may also be necessary to address drainage issues or correct the pavement’s low spots. Milling machines are often used to correct drainage, ensure that curb reveals are maintained, or smooth transitions are sustained between the overlay and adjacent pavements. After the preliminary preparations are completed, new asphalt is installed and compacted.
