Infrared Asphalt Repair: What Part of the Pavement Is Being Fixed?
Infrared asphalt repair uses heat to make existing asphalt workable so it can be remixed, reshaped, and compacted. Before approving it, ask which layer the proposed work will treat and why that scope fits the damage. A description such as seamless repair explains an intended result at the patch boundary; it does not, by itself, explain what is happening underneath the pavement.
Separate the repair method from the problem it is meant to solve
AASHTO describes hot in-place recycling as a family of methods that heat pavement, blend its upper layer with additional materials, and compact the blend in place. Its resource library includes an infrared repair specification. This is useful background for understanding the process, not a determination that any particular parking lot is a suitable candidate.
Start the proposal conversation with a plain-language question: what condition are we correcting here? Ask the evaluator to distinguish the visible defect from the reason they recommend this treatment. If a low area has returned after earlier repairs, supply those records rather than assuming another surface treatment is the next step. Request an explanation of any uncertainty before choosing a method.
Ask for a depth, not just a heated footprint
The older maintenance specification hosted by AASHTO distinguishes the measured repair area from the depth of repair. It also addresses preparation, reworking, compaction, and matching adjacent grades. Those distinctions are useful when reading a private-property quote, even though that agency document is not your project's specification.
Have the contractor identify the intended reworked depth and explain how it relates to the existing asphalt. Ask whether new material or a recycling additive is included, what material will be removed, and what remains untouched. Do not substitute a heater's footprint or a general equipment brochure for an explanation of the actual repair scope.
A useful written answer would identify the marked location, proposed method, treated depth, and exclusions together. If the proposal does not include investigating or repairing the supporting layers, ask who will decide whether those layers need attention. The point is to resolve that question, not to choose a universal depth from an online article.
Compare alternatives against the same repair objective
When comparing infrared work with a removal-and-replacement proposal, ask both bidders to describe the condition they expect to correct. A lower total is difficult to interpret if one scope treats existing asphalt while another includes excavation or work below it. Put unresolved differences into a short clarification request before selecting a proposal.
For example, ask: does this price include only the marked surface repair, or any investigation beneath it? What finding would cause the contractor to stop and recommend a different approach? Who can authorize that change? This is a decision checklist, not a claim that either method is automatically better.
For a Middle Tennessee retail property, add an operating question: which parking spaces, drive-through areas, or delivery routes must be unavailable during the work? Request a site-specific reopening instruction and identify who communicates it to tenants. Do not borrow a cooling temperature or closure duration from an unrelated agency contract.
Agree on what the walkthrough will settle
Before work starts, ask how the completed repair will be reviewed. Discuss the intended tie-in to surrounding pavement, the finished surface, cleanup, and any markings that must be restored. Keep the approved repair map with dated before-and-after photographs so a later question can be tied to the correct location.
Ask for written follow-up terms rather than interpreting seamless as a promise that cracking can never return. If a concern appears, record where it is and contact the contractor with the original scope. Milliken Corporation's asphalt page lists patching, repairs, replacements, and overlays. For a Nashville-area property, request an evaluation of the condition and available options; the page does not establish that infrared equipment is offered for every project.
Frequently asked questions
Is infrared repair the same as replacing all the asphalt?
No. The described process reworks existing asphalt with heat. Ask the proposal writer to state the treated depth and any separate removal, replacement, or supporting-layer work.
Does seamless mean the cause of the damage is fixed?
Not by itself. Ask for the assessment behind the recommendation and an explanation of how the specified work addresses the condition at that location.
Should I request infrared repair before arranging an evaluation?
You can ask whether it is an option, but bring the damage history and previous repair records first. Let the site assessment and defined repair objective guide the discussion rather than committing to equipment in advance.
