How The Infrared Asphalt Repair Works

How The Infrared Asphalt Repair Works

Out of all the developments in asphalt paving technology and techniques, perhaps the most effective is infrared repair (IR).

The process is very efficient in comparison to previous spot repair methods like the saw cut method, where the damaged asphalt cut, removed and filled with fresh asphalt. Infrared repair eliminates the seams by the feathered joining of the latest patch material to the surrounding pavement, so there is no water infiltration.

What is infrared asphalt repair?

The process of infrared asphalt repair is a technique that uses infrared rays to heat the existing asphalt pavement into a malleable substance, so the newly added asphalt can easily fuse with it.

Where can IR be used?

Specific repair methods cater to specific types of asphalt damage. For example, IR deals with:

  • Pothole repair
  • Cracking pavement
  • Gouges in blacktop
  • Uneven pavement
  • Maintenance hole transitions
  • Creating a seamless transition between the new and existing pavement
  • Dips or divots
  • Bonding speed bumps to streets
  • Utility repairs
  • Oil spot removal
  • Creating rumble strips

Where should IR be avoided?

Every asphalt project has its own set of factors and requirements that can impact the results. Below is a list of things that hinder the success of an IR project.

  • Failing base or sub-base
  • Failed surface
  • Existing asphalt is thinner than necessary, two inches or less
  • Areas of standing or pooling water
  • Excessive dirt, debris, or mud
  • Coal tar sealed surfaces
  • Traffic loads exceed the design thickness

What are the steps for infrared asphalt repair?

The infrared asphalt repair process, as compared to other methods, is quick. The steps are as follows:

1. Clean the damaged area

Sweep and dry the area using a broom or blower to remove the dirt, debris, and/or pooling water.

2. Heat the area

Position the infrared panel over the area that needs to be repaired and apply the heat of 350 degrees for the required time. Exposure time depends on the existing asphalt’s depth, asphalt mixture used, and the season. Small patches require 7-10 minutes of heat exposure, while larger areas may require up to 25 minutes.

3. Prepare the existing asphalt

Remove the infrared panel, rake the softened asphalt and gravel mixture, and mix in an asphalt rejuvenator and replenish any oxidized oils.

4. Apply the patch

Add the required amount of fresh asphalt mixture and grade the area using a lute. Once the new asphalt patch is laid, compact and fuse it with existing asphalt using a vibratory roller. Your pavement will be ready for traffic within 20 minutes or so, depending on the size of the patched area.
