After mix is added (along with an asphalt rejuvenator when needed) the repair must be compacted. Manufacturers say the most common compaction tool for smaller repairs, which most contractors already own, is a walk-behind vibrating plate. This can be enough to provide proper compaction but many contractors prefer to rely on their small rollers.
Manufacturers say that whichever equipment is used it’s important to compact the repair from the outside moving in, essentially pinching the edges where the heated pavement meets the cold pavement. This provides a better bond and can help seal the edges. It also helps create a smoother transition from the cold pavement to the repaired area.
VanVelsor adds that rollers and plates aren’t the only tools contractors should have on their trailer. “To get good compaction around a manhole or other hard-to-reach areas contractors should use a hand tamp. It’s amazing how much compaction you can get from a hand tamp.”
Overall, because infrared equipment can be used to solve a broad variety of pavement issues contractors should advance slowly but steadily into the infrared pavement repair service. “It’s important to take it gradually, understand what you’re doing and do what you can do effectively for your experience level,” he says. “Don’t be afraid to consult with the person that sold your machine.”
