Infrared Patching is the process of combining hot-mix asphalt with the existing damaged asphalt to compact the area for a smooth, seamless finish. In cold weather climates, cracks, divots, potholes, heaving, uneven or rough asphalt surfaces are often a result of several freeze-thaw cycles. Infrared asphalt repair is often referred to as cold weather patching and is a temporary solution until further pavement maintenance can be performed.
