Amarillo Pavement Pros: Infrared Asphalt Repair in Amarillo, TX

Repairing asphalt without cutting it out

Conventional patching is a removal operation. The defect is saw cut, the material is dug out, new base and asphalt go in, and the result is a rectangle of new pavement with a joint all the way around it.

Infrared repair works differently. A heater is positioned over the defect and warms the existing asphalt in place until the top couple of inches reach a workable temperature. That softened material is then scarified and raked, fresh hot mix and a rejuvenating agent are worked in to restore the binder that has oxidised out, and the whole area is recompacted while hot.

The material that ends up in the repair is largely the material that was already there, reconditioned. And because the repair area and the pavement around it are both hot when it is compacted, they fuse. There is no perimeter joint.

Why the joint is the thing worth avoiding

Every conventional patch has a seam, and the seam is the part that fails first.

A vertical saw-cut face is tacked before new asphalt goes against it, and a well-made patch bonds well. But it is still an interface between old material and new, with different ages, different stiffnesses and different rates of thermal movement. Over enough cycles, that interface is where a crack forms.

In Amarillo that matters more than in most places. NOAA engineering weather data puts the city at roughly 85 freeze-thaw cycles a year. Every one of those is differential movement working on the joint, and any water that finds it freezes and levers it wider. Patches here commonly start failing at their edges rather than in their middles, and a lot that has been patched repeatedly develops a network of cracks tracing the outline of every previous repair.

An infrared repair does not create that outline in the first place.

What it is genuinely good for

The technique suits defects that live in the surface layer.

Ravelling and oxidised areas where the binder has degraded and the surface is shedding aggregate. The rejuvenator addresses the actual problem rather than covering it.

Rough or failing patch edges from previous conventional repairs, which can be reheated and blended back into the surrounding pavement.

Bad longitudinal joints from the original paving, where two passes of the paver did not knit together properly.

Small surface depressions that hold water but have not yet caused base failure.

Utility cut repairs that have settled slightly or are cracking around their perimeter.

Oil-softened spots where drips have dissolved binder, provided the contamination has not gone deep.

What it cannot do

This is the part that deserves plain speaking, because infrared is sometimes sold as a universal patch.

Infrared heats the surface. It does nothing whatsoever for the base underneath. A pothole that exists because water got into the base and took its bearing strength away is a structural failure, and reheating the two inches above it produces a smooth, well-bonded repair sitting on ground that still cannot carry load. It fails again, and it fails quickly.

The diagnosis is the same one that governs all asphalt repair. If the base is sound and the defect is in the surface, infrared is an excellent and economical answer. If the base has failed, the area needs saw cutting, excavating, rebuilding and repaving, and no surface treatment substitutes for that.
