As the rays are absorbed the asphalt is heated without the surface burning. Conversely, attempting to heat asphalt with an open flame, hot iron, or heated air (convection heat) will burn the asphalt long before it is adequately softened.

Unique infrared converters are extremely efficient generators of Infra-red energy. They are designed to concentrate the infrared hear directly into the asphalt while venting away excess convection heat. In comparison with a cold/hot patch, even when done correctly, the finished repair is left with a cold seam where hot asphalt from an Infra-red meets the existing pavement.

With a cold patch this cold seam is the “weak link” and it is where water will eventually re-enter the repair and cause it to fail. Infra-red is a higher cost fix, but is a proper fix that in time will save your asphalt with fewer repairs and a cheaper overall cost.
