This article provides readers with a quick review of infrared asphalt restoration and repair (IRR), defined as the absorption of radiation (heat) into damaged asphalt in order to aid in removal. After the damaged material is removed, it is replaced with new or reclaimed material and heated again to bond the patch with undamaged areas. The author focuses on some of the details that must be kept in mind for this technique: proper heating of the asphalt; the impact of different types of asphalt on IRR; the role of moisture, wind and temperature; preparation of the surfaces to be patched; the use of rejuvenators; the need to attend to subgrade failures; and the use of heat shields. The author concludes by reminding readers that employees must undergo on-site training as part of the process of using this technique effectively.
