Full Depth Patching
Full depth patching involves removing and replacing portions of asphalt. The goal of the replacement is to remove areas that of old asphalt that have deteriorated. When doing a full depth patch, the perimeter of the area is cut by saw and then removed. After that, hot mix asphalt is poured into the open patch. The asphalt is then compacted to a smooth finish.
Infrared patching is a method of heating the existing asphalt and reblending it with the pavement. Once blended, a joint-free integral patch results. Infrared is an invisible wavelength that carries heat. Our repair unit uses this to recycle asphalt in-place. It’s heating elements produce intense infrared waves that are directed into the asphalt surface. When the asphalt gets over 300 degrees it can be reworked, allowing new asphalt to be added. Once reworked, the asphalt is compacted so the result is a smooth surface.
