Infrared technology is a phenomenal way to repair a wide variety of asphalt problems including asphalt that was improperly installed. While the process seems simple and straightforward, it is surprisingly complex. Here are some of the things that you need to know about infrared asphalt repair technology.
What is Infrared Asphalt Repair?
Infrared asphalt repair uses radiation or heat that is applied to the damaged asphalt to help remove the damaged material. Next, new asphalt or recycled asphalt can be heated and bonded with undamaged areas. The heating process can be complicated, as each layer of asphalt needs to be individually heated and raked away before the layers below can take in the heat and be removed. The infrared asphalt repair team also needs to determine the composition of the asphalt being removed, as every mix can have slightly different properties and heat quickly or more slowly. Old asphalt takes longer to heat and repair than newer asphalt.
Factors that Determine Success
Some of the key factors that determine the success of your infrared asphalt repair include:
- Moisture: This should be avoided at all costs. A small amount of water can evaporate during the infrared heating process, but the heat and water together can damage other portions of the asphalt and leave other parts too wet.
- Wind: Windy days require a longer time for repair and can have slightly less successful repairs.
- Ambient Temperature: Hot days are better for initiating repairs, as the ground is already heated a certain amount, but if they are excessively hot it can take a while for the final product to set.
The Infrared Asphalt Repair Process
Patch prep is another crucial part of the process. Once the old material has been removed and disposed of, the edges of the area will be straightened and tapered. The tapered edge helps to facilitate a strong bond between the remaining old asphalt and the new material. Next, new asphalt will be added to the area and integrated with any remaining material. Infrared asphalt repair can also involve a subgrade repair so that the same problem does not occur again.
