4 Common Asphalt Patching Techniques For Your Cracked Or Pot-Holed Asphalt Surface

Posted on

Asphalt is a mixture which consists of bitumen, sand, and aggregate. It's commonly used for roads, driveways, and footpaths in both residential and commercial environments. If you have an asphalt surface in or around your home, you may have noticed cracks or potholes developing on the surface. There are four asphalt patching techniques which are commonly utilized to fill cracks, pot-holes, or other damage to pavement.           

Technique One

The "throw and roll" technique is usually used as a temporary measure for patching. This technique involves liquid asphalt, which is poured into the cracks or holes and then rolled over by a specialized machine. Generally, no preparation of the cracked surface is performed. This technique is typically completed in cooler weather, as it is only used when emergency patching is required.

Technique Two

A technique used for a more robust job than the "throw and roll" technique is applying semi-permanent patches. These patches require some surface preparation, which entails the removal of any debris with the assistance of an air compressor. The area is scored with power equipment before it is filled with the mixture and compacted with a roller. This method will last a decent amount of time on low-traffic surfaces.

Technique Three

This next technique is called the spray-injection method. This method requires truck-mounted equipment, which is used to thoroughly remove any debris from the specified area. Once this process is complete, damaged areas are then injected with an asphalt-based emulsion.

Because of the use of the truck-mounted equipment and the pressure which is required to insert the mixture, there is no need to compact the area after the patch is applied. This technique is used when a high-quality and long-lasting repair is required.

Technique Four

The last technique is the full-depth-patching method, which is considered the apex of asphalt patching. This method is the most permanent method of all of the four commonly used techniques. The full-depth-patching method requires an excavator to remove the entire damaged area of the damaged surface. The surrounding area is also excavated slightly, which will provide more support to the repair zone.

Once the area has been prepared correctly, a base coat is inserted into the entire area, followed by a layer of asphalt mixture, which fills in the hole. Finally, a bonding agent is back-filled into the repair area, which connects the new asphalt with the existing surface.

If you have a section of road, a driveway, or footpath with cracks or potholes, getting it repaired is a priority. Neglected asphalt repairs can become worse and more difficult to fix over time, and can also cause injury to you or your loved ones.
