Patching is widely known as the process of filling potholes and excavated areas in asphalt pavement. Quick potholes repair aid to control the deterioration and expensive repair of potholes. If patching doesn't perform time to time then it may lead to water sub grade that ultimately results to the serious pavement failures.
Deep patch or full depth patch is work as permanent repair whereas "throw and go" or thin surface patch is commonly as temporary pothole repair. Material for patching contain asphalt emulsion mixes, hot mix asphalt, proprietary patching mixes and stockpile patching mixes as well. All these combined together with blends of modified and aggregate binders.
Despite of its thickness, full depth patching procedure helps in removing the entire pavement over the patching area. Thus, deep patching eliminates about four or more inches of pavement surface. Deep patching is applied to both concrete or asphalt pavements while thin surface patching only applies to asphalt pavements.
Why Patching Is Important For Pothole Repairs?
The most important reason behind the pothole spray patching is that it provides firm support. This simply helps to remove some of the sub-grade. Full depth patch actually requires some additional drainage.
Therefore, deep patch must be filled with the dense graded hot mix asphalt. But in case, asphalt mix is not available, you can use specialty mix, appropriate cold mix and proprietary mix.
If patch level is more than 6 inches deep, then place patching compound in 4 inch layers to compact each layer when it is placed. However, there are many pothole repair methods but the best pothole repair methods is patching. Pothole Patching Machine can serve the best repair means for your asphalt surface.

The operation includes cleaning of patch area using compressed air to remove loose debris or material. After that a small coat of hot asphalt emulsion placed over it. Then place dry aggregate coat of patch on it to prevent tracking.
#3. Infrared Asphalt Patching
Despite of the fact that Infrared heating patch needs few workers, this method work often cheaper and faster compared to full depth patching. Infrared asphalt patching is also truck mounted to heat the asphalt till the depth of 2 to 3 inches which is quiet thin surface patch.
Further patch area is heated using scarified and infrared heater. Rejuvenators then work into new asphalt or in-place asphalt mix together into existing material. Finally, after reworking the existing asphalt get compacted.
