Infrared asphalt repair is a localized repair technique that heats existing pavement, allows it to be reworked and blended with new asphalt, and produces a seamless thermal bond rather than a cold-jointed patch. For specific failure types — potholes, utility trench joints, isolated raveled areas — infrared can be the right tool, with faster cure, no cold seams, and better long-term performance than a sawcut-and-fill patch. It is not a substitute for reconstruction, drainage correction, or resurfacing. This guide explains where it fits.
How the process works
- An infrared heating panel is positioned over the repair area for 6 to 10 minutes, softening the existing asphalt without burning it.
- The softened asphalt is raked and reworked, removing failed material and loosening the surrounding edges.
- New hot-mix asphalt is added and blended with the heated existing material.
- The combined material is compacted to grade, producing a thermally bonded patch with no cold seam.
- The patch is cooled and reopened to traffic — typically within an hour.
Why thermal bonding matters
A cold-jointed patch — material placed against an unheated edge — is held together by the bond at that joint. Water infiltrates the joint, freeze-thaw widens it, and the patch typically fails at the perimeter first. An infrared repair eliminates the joint by blending the new and existing material into a single mass. The failure mode disappears.
Where infrared fits
- Isolated potholes, especially recurring ones.
- Utility trench restorations where the joint between trench fill and original asphalt is the weak point.
- Raveled or surface-failed areas smaller than 30 square feet.
- Repairs at dumpster pads, dock approaches, and other concentrated-load zones.
- Cosmetic improvements in high-visibility areas like main entries.
Where it does not fit
- Base failure — heating the asphalt does not fix what is moving underneath.
- Large areas where mill-and-overlay is more cost-effective.
- Cold weather below approximately 40°F, when heating cannot achieve workable temperatures.
- Wet pavement — moisture must be driven off before patching.
- Areas where drainage is the underlying cause; infrared without drainage correction will fail.

Cost and durability
Per-patch cost is higher than a cold patch but lower than a sawcut-and-fill repair. Lifespan is dramatically better — infrared patches typically last as long as the surrounding pavement, while cold patches often fail within one or two winters. For repeat-failure locations, infrared usually wins on lifecycle cost.
When to use infrared vs alternatives
- Infrared: isolated repairs, utility trench joints, cosmetic high-visibility patches, repeat-failure locations.
- Cold patch: emergency temporary repairs only, expected to be replaced within a season.
- Sawcut-and-fill: medium-size repairs where infrared is impractical or the failure pattern requires removal of larger material.
- Mill-and-overlay: when patch count grows beyond the threshold where individual repair makes economic sense.
Property-type considerations
- Retail and high-visibility lots: cosmetic continuity matters; infrared blends visibly better than cold-jointed patches.
- Apartment and HOA: smaller scope and quick reopening make infrared a fit for occupied properties.
- Industrial: dock approaches benefit from thermal-bonded repairs that resist the concentrated loading that originally caused the failure.
- Municipal: utility trench restoration is a major use case; infrared often included in roadway maintenance programs.

Common questions
How long does an infrared patch last?+
On a sound base, an infrared patch typically lasts as long as the surrounding pavement. The thermal bond eliminates the joint failure that limits cold-jointed patches.
Is infrared more expensive than other patching?+
Per patch, yes — but the cost per year of useful life is usually lower because the patch does not fail and need replacement. Lifecycle cost favors infrared for repeat-failure locations.
Can infrared be done in winter?+
It depends on temperature. Below roughly 40°F, the process loses effectiveness; below freezing, it is not practical. Emergency winter repairs are typically cold patches replaced with infrared or sawcut-and-fill in spring.
How quickly can the area be reopened?+
Usually within an hour of compaction. The patch is cooled to ambient temperature, not curing chemically, so it can carry traffic immediately.
Does infrared work on alligator cracking?+
Alligator cracking indicates base failure. Infrared heats the surface; it does not address what is moving underneath. Treat the base first.
What about repairs around manholes and catch basins?+
Infrared is well suited to repairs around structures because it bonds to the existing edge without a cold joint. Many utility trench restorations are completed with infrared for exactly this reason.
