What You Should Know About Infrared Asphalt Repair

Posted on: 18 January 2018

You might have heard of infrared asphalt repair or patching as a means to fix damaged and cracked asphalt. This can be done on either your driveway or, in some large cities, the technology is being used to repair highways and other roadways. What should you know about infrared asphalt repair before hiring a contractor to complete it for you?

What Is It?

Infrared asphalt repair is a solution for fixing cracked or damaged asphalt on driveways or on roadways. This solution can help prevent pavement failures and is an effective alternative to cold patch asphalt.

Infrared asphalt repair involves heating up an area of cracked or damaged pavement to the point where it is workable and then raking up the loosened pieces and smoothing them back into place. In other circumstances, the loosened pieces are taken up and replaced with brand-new asphalt

This method is used to repair newly installed asphalt on a driveway or roadway; to repair frost heaves, where the extremely cold temperatures have caused the asphalt to buckle; to repair elevated areas, such as around manhole covers; and to help bond speed bumps.

How Does It Work?

Infrared asphalt repair works by using radiation or heat absorption into the damaged asphalt to help break it down and remove it. Once the asphalt has been removed, workers can then replace it with brand-new material or reheat the existing material to re-bond it with the surface to repair damaged areas.

Each layer must be melted individually and raked off the top so each succeeding layer can absorb enough heat for its removal. The quality of material in the asphalt and what type of material went into making it will affect on how long it will take to heat it. This means that polymer grades, the mix design, and the age of the pavement all play an important role in heating times. The older the asphalt, the longer it will take to heat.

When using the infrared asphalt repair technique, you must keep a few things in mind. For example, you should avoid getting moisture onto the pavement if possible. While water will evaporate during the process, it will heat up excessively and could damage the surrounding areas of asphalt while other areas stay wet.

You also need to take into consideration the type of weather you are having that day. Both wind and temperature will affect your heat times, and the weather will also affect the material you are working with, possibly preventing it from staying pliable during the repair.
