Remove and replace or “R&R” is another option and is most used in areas that have more severe damage, and the underlying base is compromised. The process for this repair is to start by squaring off the area that needs repair and saw cutting to get nice clean edges. The old and damaged asphalt is removed. The base is inspected, and stone is added if required, then compacted in preparation for the new asphalt. Hot-mixed asphalt is then added over the base and compacted. HD Sealcoating and Paving highly recommends adding crack fill and sealcoating to this type of repair. After the hot rubber crack fill and sealcoating is done you can expect the surface to blend nicely with the original asphalt. This option, while more expensive than an overlay, or surface repair, has a nicer more uniform look with the existing pavement and can be expected to last about 15 years with proper care and maintenance.
Cold-Patch is not considered a repair for damaged pavement, but rather it can be used to temporarily patch a bad pothole that occurs during the winter when we are not able to do a proper repair because of weather restraints. The process for a cold patch repair is to place a cold asphalt mix into the damaged area and to pack it as much as possible to prevent further damage until the time that a better, more permanent repair can be made. Cold-patch repairs usually only last two to six months.

Asphalt Repair
The best way to increase the life of your pavement and maintain its integrity is through regular maintenance. Repairing pavement failures as they occur will help prevent large, expensive repairs in the future, as well as avoiding dangerous trip hazards and damaging potholes. The most common causes of pavement deterioration are water accumulation in areas of lower elevation, excessive loads on the asphalt, and the destructive effects of vehicle oil and gasoline. Over time, water accumulation can cause asphalt to crack, or cause allegation, or spider-web cracking. Excessive weight can cause the asphalt to sink, and oil and gasoline that seep into the asphalt can cause further deterioration. Depending on the extent of the damage and budget different repair options are available.
Overlay, or surface patching, is one option that is available when the area that needs to be repaired has a sound base. The process for this type of repair is to clean the area of all debris, apply an asphalt binder, or tack coat, around the repair area and apply hot-mixed asphalt that is then compacted down. Since the new asphalt is placed on top of the existing asphalt there could be up to a one-inch rise between the repaired area and the existing pavement. The edges of the new pavement are blended to the existing pavement as much as possible. This type of repair is reasonably priced for those on a budget and can be expected to last approximately three to five years. In some situations, however, this repair option may not be available if the base is compromised.
