Infrared patching takes between 20 and 30 minutes to complete and traffic can continue shortly after. To perform the procedure, the area to be repaired is marked. A 6' x 8' infrared unit heats the asphalt. After heating, the asphalt is raked away and new asphalt laid down. In the meantime, cracked surfaces continue to deteriorate and cause more damage. This leads to higher repair costs and an increased risk of accidents.
Throw-and-roll method
There are two main types of pothole repair methods: the throw-and-roll method and the spray-in method. The former is used to temporarily patch a pothole, while the latter involves repairing it permanently. In the throw-and-roll method, the pothole is filled with asphalt patch materials, which are then rolled over by heavy vehicles. The throw-and-roll method is a temporary solution, which is why it's commonly used during the winter when the roads are most likely to be damaged. However, the method is very labor-intensive and expensive.
When you use the "throw-and-roll" method, you simply shovel the patch into the pothole and roll it into place. This method is usually used during the winter months because it does not require compaction. The throw-and-roll method is more effective when using high-quality materials, which will ensure the pothole patch stays intact and lasts for a long time. However, it only works well in sub-zero temperatures.
Surface seal
One of the most common and effective pothole repair methods is to use a surface seal. The idea behind this type of repair is to fill the pothole with a material that binds to the surface and is flexible enough to go into cracks and other areas of the road. This material is relatively inexpensive, and it can be applied easily by hand, without the need for special equipment. After preparing the area, the surface seal can be applied.
Crack sealing is best done in moderate temperatures and immediately after the crack has developed. It's crucial to route out and clean out cracks before applying sealant. Fog seal is a light application of diluted asphalt emulsion that will restore flexibility to aged pavement. It may also postpone the need for a BST or non-structural overlay. While fog seals aren't always effective for pothole repair, they may be an excellent option for pothole repair.
Full-depth patching
Full-depth patching is the preferred method for repairing potholes. Full-depth patching involves the application of asphalt over an existing pothole. The materials used must be fresh hot asphalt plant mix and meet the requirements set forth by the Colorado State Highway Specifications. You can request a manufacturer's certification upon request. Full-depth patching will increase the strength and durability of the asphalt overlay. Listed below are some tips on how to patch a pothole using full-depth patching.
Full-depth patching requires removing four inches or more of the top layer of asphalt or concrete. In some cases, excavation tools may be necessary. This process is more difficult and may require removal of drainage or sub-grade. The patch is then filled with a dense hot mix asphalt mixture and leveled. A well-filled patch is slightly overfilled. It may be necessary to repair drainage beneath the damaged area before applying the asphalt patch.
