Key Facts You Should Know About Infrared Asphalt Repair

Infrared asphalt repair (IR) is an advanced and highly effective asphalt repair method that uses an infrared heating unit for in-place heating of the old asphalt. It softens and becomes more workable, and new asphalt is added so it can fuse with the old material. If you need quick hot asphalt repair, then this is the solution for you.

If you want to learn more about this contemporary asphalt repair technique, read the eight facts below. 

1. Infrared restoration is the absorption of radiation (heat) into the damaged asphalt areas for easy removal, all the way up from the sub-base. After raking away the debris, a rejuvenator is applied before reclaimed or new asphalt is installed and reheated, so it bonds with the existing undamaged pavement and compacted using a multi-ton vibratory roller.

2. Rejuvenators are applied to replace the maltenes (light oils of the asphalt cement) that are oxidized out of the asphalt material during the IR process or over its lifetime.

3. Infrared patching requires proper heating. Generally, the process takes 15 to 20 minutes depending on the season, air temperature, season depth, and existing aggregate (around 1 to 3 inches), determining the time the asphalt would remain workable.

4. All layers of the asphalt pavement need to be individually heated and raked off because sufficient radiation does not get absorbed by the lower levels.

5. The material properties and percentage of asphalt have a direct effect on the heating times. Mix designs, the age of the material, and polymer grades all affect the infrared process. Aged (white) asphalt does not absorb heat the same way as new (black) material.

6. All moisture needs to be removed before IR is used; otherwise, certain areas of the asphalt might get damaged due to excess heat during evaporation while more porous areas stay wet.

7. After the old material is heated and removed, the pit’s edges need to be squared off and tapered to obtain a lasting repair. A tapered edge provides more surface area to ensure that a good bond is created between the new and old surface.

8. When using new and reclaimed asphalt in the repair, both materials need to be adequately raked and mixed, so the old and new asphalt material does not segregate.

9. Some state and local regulations do not allow heating near sewers and drains, in which case heat shields can be used as a thin sheet of aluminum to deflect the IR away from these places and directly on the damaged area.
