How to Patch with Infrared Tech
BY Rudy Curtler
If the pavement structure doesn’t require repairs to the subbase to resolve a rutted, alligatored or other problem area, you may be able to complete a repair with infrared patching, rather than sawcut and fill. Here are the steps to make it a successful job.
- Step 1. Heat the area to be repaired.
- Step 2. Scarify (or rake) the now-malleable section.
- Step 3. Add and blend in fresh pavement mix so you have a fluff factor for rolling. You’ll select hot-mix asphalt, a cold patch material or other mix based on the needs of the client, pavement, traffic loading and so on.
- Step 4. Compact the repair flush to the surface of the surrounding pavement.
- Step 5. Stand back and admire your handiwork.
If you’ll be sealing over the pavement, assess the project to see if repairs need a day (or longer) to cure. By spraying or squeegeeing sealant over an oxidized pavement with a number of fresh patches, you risk uneven application and absorption rates. Giving the new spots a minimum of 24 hours helps maximize sealing success.
