To paraphrase an old saying, an ounce of preparation is worth a ton of cure. Regardless of what needs to be repaired, proper preparation is the key to achieving the desired results. When they are getting ready to make repairs to your asphalt pavement, your contractor’s crew members will make sure that the work area and the area to be repaired have been prepared correctly.
POTHOLE & ASPHALT REPAIR PREPARATION – CONTROL TRAFFIC
Traffic control ensures the safety of the workers as well as anyone who might venture onto your property. Depending on the circumstances, traffic control may involve erecting barricades, taping off the area, placing signs or using flaggers to direct traffic.
POTHOLE & ASPHALT REPAIR PREPARATION – MARK THE DAMAGED AREA
Workers may use chalk to draw attention to cracks that need to be repaired or to mark the area around a pothole that is to be removed. If pavement is to be removed, the chalk lines will normally encompass an extra foot or so of sound pavement. Pavement that must be removed will be cut out.
POTHOLE & ASPHALT REPAIR PREPARATION – CLEAN THE AREA
Whether it is an area where the pavement has been removed or a crack that needs to be filled, the workers will clean it thoroughly. There are various tools that can be used for cleaning. For example, compressed air may be used to blast out any debris, a drill-mounted wire wheel may be used or a heat lance may be employed to clean a crack. If the walls inside the crack are particularly jagged, a router may be used to smooth them or widen the crack a bit.
POTHOLE & ASPHALT REPAIR PREPARATION – DRY THE AREA
The interior of the crack or hole must be dry for proper adhesion to occur. Hot air is often used for drying, but an increasing number of contractors have embraced heat lances for ensuring that cracks are sufficiently dry.
POTHOLE & ASPHALT REPAIR PREPARATION – PREP THE SIDES AND BOTTOMS
The type of repair dictates the precise preparation needed. For example, for a pothole repair involving the removal of the old pavement, a tack coat may be applied to the sides of the existing pavement to ensure a strong bond. In some instances, it may be advantageous to insert a special fabric into a crack before filling it.
POTHOLE & ASPHALT REPAIR PREPARATION – IMMEDIATELY INSTALL THE REPAIR MATERIAL
Once the area to be repaired has been cleaned, dried and prepped, the material should be installed immediately to prevent dirt or moisture from intruding. The choice of material depends on the nature of the repair, the weather and the condition of the surrounding pavement. If pavement has been removed, it will probably be replaced with hot-mix asphalt that is applied in layers; each layer will need to be compacted before the next course is applied. When it comes to crack filling and sealing, your contractor will have a number of options from which to choose. He will base his decision on the size of the crack, whether the crack has been expanding, the temperature and other factors that could affect the longevity of the repair.
