From parking lots and driveways, to side streets and thoroughfares, divots, cracks and potholes are not hard to find. Asphalt, the material used to make and repair driving surfaces, contains coal tars and fine gravel. When asphalt is first laid, it is heated, spread out evenly, and then compressed into place. Upon the asphalt cooling, it will become hard enough to retain its shape under the weight of vehicles. However over time, uncontrollable variables will break down the asphalt, unfortunately resulting in cracks and holes. Traditionally, potholes have been filled with what is called a cold patch, which is an asphalt repair material that is laid, spread, compressed and left to set and seal. But, thanks to advances in infrared technology, Infrared Road Repair (IRR) provides a better way to repair roads making it the newly preferred method.
What is IRR?
IRR combines hot-mix asphalt with heat and the existing damaged asphalt to create a seamless, longer-lasting surface. If you have potholes, deep or shallow, hire a professional asphalt and sealing company to repair them with IRR. Beyond potholes, IRR can also be utilized for cracks, heaving, or uneven areas.
The IRR Process
First, the affected area will be blown and swept clean. In some cases, rejuvenators are added to restore any oils lost due to oxidation. When all loose particulates are removed, the surface is heated, allowing the absorption of radiation (heat) to aid in the removal of failed aggregate. Next, the affected area will be filled with new or reclaimed material and heated again to ensure the material properly bonds. It is important to note that multiple layers will be heated individually due to the percentages and properties of asphalt. For example, a new black material will absorb heat more so than aged, white material.
Once the pothole has been raked and graded to the proper level, it is compressed with a multi-ton roller or plate. Unlike other methods, IRR does not cause burning, scaling, or separation of aggregate. IRR also allows for deeper asphalt repair and takes less time than traditional methods. Lastly, IRR offers more water resistance to the porous asphalt, aiding in the repulsion of material breakdown.
Why Choose the IRR Method for Pothole Repair
- Less expensive: this method uses fewer materials
- IRR process takes less time
- Offers more water resistance to the material and area affected
- Can be driven on immediately, causing less traffic interruption
- Due to proper bonding, surface has a smoother finish
