STANDARD REPAIRS
The asphalt being repaired is heated with our state of the art infrared heater that operates at temperatures in excess of 1200 degrees. Infrared heat generates even heat throughout the asphalt and does not burn or scorch the asphalt as other heaters may do that do not operate at the necessary temperatures to produce true infrared heat. Once heated, we edge the perimeter of the repair to create a clean, straight line to the repair. We then run a heavy duty commercial tiller inside the edged area to break down the asphalt to its original granular form. Since the asphalt has been heated to its ideal working temperature of 350 degrees it breaks down very easily. Rejuvenator (the required oils and bonding agents) is added while tilling the asphalt so that it is mixed thoroughly and evenly throughout the asphalt. Once completed we begin raking the asphalt to level, adding new, hot asphalt as needed to fill in low areas and build up the area to the proper level. The raking continues until the asphalt is perfectly leveled and ready to be compacted with our vibratory roller. First the edges are compacted fusing the repair to the existing asphalt surrounding the repair. The repaired asphalt fuses or presses into the existing asphalt because we heat several inches beyond the perimeter of the repair, so the existing asphalt surrounding the repair has also been heated to 350 degrees. The vibratory roller compacts and presses the repaired asphalt in with the existing asphalt surrounding the repair making it one continuous layer, just like when it was new. We continue rolling the entire area until the asphalt is completely compacted. The crew sweeps up around the repair and then moves on to the next, leaving the area completely clean and finished.
The Fusion and Infrared Heat process is much less intrusive and disruptive than the saw cut method because there is no saw cutting, no large equipment tearing out asphalt, no dump trucks to haul the asphalt away, and no big mess being created by all this equipment and the removal process. With our method, we are generally able to work in very busy locations while the business is open to customers with little or no impact.
SUB-BASE REPAIRS
Some repairs may require that the asphalt be removed due to sub-base damage. When this is the case we remove the asphalt, add more sub-base material if necessary and compact. Then we heat the perimeter of the repair with our infrared heater. Once heated, we add new, hot asphalt to build up the area to the proper level and begin raking until it is perfectly leveled and ready to be compacted with our vibratory roller. Again, we compact the edges first to fuse the repair with the existing asphalt surrounding the repair. We continue rolling the entire area until the asphalt is completely compacted. Clean-up is completed before moving on to the next repair. In this case we have repaired the sub-base in the same manner as the saw cut method, but in addition, we have given you a seamless repair as the repaired asphalt is fused with the existing asphalt surrounding the repair, making it one continuous layer of asphalt, something you do not get from the saw cut method.
