Infrared Asphalt Restoration


Infrared asphalt restoration offers a much faster repair, which means minimal traffic disruption. Seamless repairs thermally bonded to existing surface leaves no cold joints allowing water intrusion preventing future failures while using less materials and less man power. Our process is also environmentally friendly by recycling existing material. Infrared asphalt restoration is the highest quality, most economical method available for most all asphalt repairs. It is also the only “green” method for making repairs. What makes this method so environmentally friendly is recycling up to 90% of the existing asphalt. This is also what makes infrared asphalt restorations considerably less expensive than the traditional saw cut, remove and replace method. The traditional methods requires contractors to cut and remove damaged area then haul off, haul in new material, then complete the repair. When completed they are left with a saw cut line (cold joint) around the perimeter of the repair which allows water intrusion and ultimately the premature failure of the asphalt.

Applications:

  • Utility Cuts
  • Potholes
  • Bird Baths (puddles)
  • Joint Failure
  • Manholes
  • Storm Drains
  • Grade Issues
  • Oil Spot Removal
  • Bridge Joints
  • Alligator Cracking
  • Bumps

Infrared Process: Conventional vs. Infrared

Repairing asphalt by conventional methods is a very expensive and time consuming process. It requires a significant amount of equipment, material and manpower, and the results are often far from permanent. Even when done correctly, the finished repair is left with a cold seam where hot asphalt meets the existing pavement. This cold seam is the “weak link” and is where water will eventually re-enter the repair and cause it to fail. You can see this starting to happen in the photo below.

How do you save with Infrared?

Time: Repairs can be made in a fraction of the time of conventional methods. A typical 5 x 7’ repair takes 20
minutes to complete. The road can be re-opened to
traffic immediately after the repair.

Quality: The thermal bonding of the asphalt repair with
the surrounding pavement makes the repair an integral
piece of the pavement. No cold seam is left for water
to re-enter and cause joint failure.

Recycle: Existing asphalt is reused, leaving little or no wasted
material. This means less handling and disposal costs.

Labor: Repairs are fast and simple. Two men and twenty
minutes are all that are needed for a typical repair.

Cost: The savings realized in materials, manpower and machinery make infrared repairs less expensive than conven-
tional repairs. Traditionally, good asphalt is cut out, removed,
and replaced with new material. This is typically not necessary.
All of these things require a great deal of time, travel, material,
equipment, and labor which = more $$$. On-site recycling
eliminates all of these factors. Aside from having a more
permanent repair, infrared asphalt restoration is considerably
less expensive and environmentally friendly!

Take a look at what the conventional process requires:
Equipment:

(1) Pavement saw to cut around the damaged area
(1) Jack hammer to break up the existing pavement
(1) Bucket loader to excavate the hole and remove waste asphalt
(2) Trucks – One for excavated material and one for fresh asphalt
(1) Roller to compact the repair

Manpower: Enough labor to operate trucks
and equipment plus do the hand work

Material: Large quantity of asphalt
to replace excavated material

Time: All the steps involved can take 2-3 hours for a typical 5 x 5’ repair

Step 1: Loose debris and / or standing water is swept away from the repair and surrounding area. (Infrared is not readily absorbed by light colored materials like sand or snow)

Step 2: The chamber is lit and positioned over the area to be repaired with at least 12″ of heated area beyond the perimeter
of the repair.

Step 3: Heat is allowed to penetrate the area for 7-10 minutes.
To insure proper heating time, the surface temperature of the asphalt is checked at 7 minutes and every minute thereafter
using an Infrared thermometer.

Step 4: The heater is removed and the softened asphalt is raked.

Step 5: A maltines rejuvenator is sprayed onto the heated area. This replaces some of the light oils that have oxidized over time.

Step 6: Fresh asphalt is added from the reclaimer with lute
to correct the grade.

Step 7: The repair is compacted using a vibratory roller. The edges are rolled first to fuse the repaired area with the heated
but untouched surrounding pavement.

Although the color is different, the finished repair is now
an integral part of the existing road.
