How to Price Asphalt Patching: Potholes Per Sq Ft and Ton

Here is how to price asphalt patching: pick the method, measure each hole's area and depth, cost the material by the bag or the ton, add time on site and the trip, and set a minimum so three small holes still pay. The rate per square foot runs higher on a small job because the trip costs the same for 6 sq ft as for 200.

How to price asphalt patching: the four methods and what FHWA found

The method decides the material, the team and the minutes, so pick it first. The US Federal Highway Administration's 1999 manual of practice on pothole repair collects the good practices from the SHRP maintenance studies, and FHWA's write-up of those studies names the four techniques tested: throw-and-roll, edge seal, semi-permanent and spray injection.

FHWA's Focus article on the study reports that more than 1,250 cold-mix patches were placed at 8 test sites across the United States and Canada, that 56 percent survived to the last check in 1995, and that throw-and-roll proved as effective as semi-permanent in most situations and more cost-effective. This post prices those two.

Step 1: Measure and classify the patch: area, depth, edges, water

Measure the cut, not the hole. Pavement Interactive's patching page splits patches into full-depth, from the pavement surface to the subgrade, and partial, which do not extend through the full depth of the existing pavement.

• Area: length times width of the cut, per hole; the saw line runs into sound pavement, past the hole.
• Depth: inches to firm material; it sets bags or tons.
• Edges: a hole inside alligator cracking is a base problem, not a pothole.
• Water: standing water means drying time, or a material that tolerates it.

The free satellite tool measures the lot's total square footage; a pothole shows in the imagery only sometimes, so the tape wins.

Step 2: Cold patch vs hot mix: material by the bag or by the ton

Cold patch comes by the bag, hot mix by the ton. Pavement Interactive says HMA is typically used for permanent patches while cold mix is often used for temporary emergency repairs; FHWA adds that with quality materials a cold-mix patch can last several years.

A dated bag price: Home Depot listed Road Rescue 50 lb asphalt repair at $33.98 for pickup at its Williston, Vermont store on October 13, 2026, covering 7 sq ft at a depth of 1 inch. That is $4.85 per sq ft per inch of depth, so a 2 sq ft hole 2 inches deep uses 0.57 of a bag.

The formula for tons from area and depth, and the waste allowance, live in how to calculate asphalt tonnage; its 200 sq ft patch example supplies the tons below, priced at Kentucky's 2025 average unit bid prices, a US state DOT record: $105.11 per ton for a surface mix and $102.63 for a base mix, highway quantities that stand in for the plant's dated quote. Ask the plant about its smallest load, and a hotbox keeps a small load workable.

Step 3: Team time per patch

For the semi-permanent patch, Pavement Interactive, quoting FHWA, lists: remove water and debris; square up the sides so they are vertical with intact pavement all around; place the material mounded in the center and tapering to meet the pavement flush; compact from the center out with a vibratory plate or a single-drum roller; check for a slight crown.

Throw-and-roll is three steps: place the material without any preparation or water and debris removal, compact it with the patching truck tires, usually 4 to 8 passes, and check for a slight crown.

Neither page gives minutes per patch, so this post uses labeled planning figures: two people and 10 minutes per small hole for bagged cold patch, and four people on site for 2 hours on a 200 sq ft partial-depth patch or 4 hours on a full-depth cut-out with hot mix. Replace them with your own timesheets.

The wage floor is public: O*NET's wages page for highway maintenance workers, from BLS May 2025 data, gives a US median of $24.16 per hour. The examples use the bare median; burden, insurance and margin sit on top.

Step 4: Asphalt repair minimum charge and mobilization

The minimum charge is the trip plus the first labor hour, before margin, and it is why three holes cost more per foot than one 200 sq ft cut-out. The trip costs the same for two bags or nine tons: an hour of travel for two people at the BLS median is $48.32, and 30 miles at the IRS business mileage rate of 76 cents a mile (July 1 to December 31, 2026) is $22.80, so the truck costs $71.12 before any work.

Spread $71.12 over the 6 sq ft of three small holes and it is $11.85 per sq ft; over 200 sq ft it is $0.36. Price the trip as its own line, or fold it into a minimum covering the trip, the first hour of two people ($48.32) and margin. Three holes and a sealcoat on one visit pay the trip once, the case for selling the maintenance visit, not the hole.

Step 5: Pothole repair cost per square foot, by method and depth

The table is this post's own arithmetic from Steps 2 to 4, not a survey. Cold patch: the bag at $4.85 per sq ft per inch, and 10 minutes of two people per 2 sq ft hole, a third of a labor hour at $24.16, or $8.05 a hole. Hot mix: the tons from the tonnage post's 200 sq ft patch, 3 tons of surface mix at $105.11 ($315) for the 2 inch lift, and 6 tons of base at $102.63 plus the same 3 of surface ($931) for full depth, with four people for 2 or 4 hours. Add the trip, equipment and margin.

Throw and roll pothole repair or a cut-out: what to tell the customer

Offer two prices, in the study's terms: FHWA found throw-and-roll as effective as semi-permanent in most situations and more cost-effective, with quality materials keeping a patch in service for several years, and Pavement Interactive says permanent patches typically use HMA. The throw-and-roll holds the hole until the lot is resurfaced; the cut-out with hot mix is the repair where the base is sound.

Say what the price leaves out: a crack running from the hole is a crack sealing line, and a sealcoat over the patch waits for the mix to cure, which the sealcoating temperature post covers.

How to estimate asphalt repair from photos

Quote from photos for the method and the count; inspect before the price is final. Ask for one photo of each hole with a tape or a boot in it for scale, a wide shot of the edges, and whether water stands in it after rain. Class each hole as a throw-and-roll or a cut-out; the small ones go against your minimum, the cut-outs per sq ft at the depth you expect.

In MakeHay, a request form carries the built-in Job site address question and a Photo upload answer type, and Convert to customer + quote makes the customer, job site and draft quote. Write "subject to inspection" in the quote's Terms field and ask for a deposit, a percent or a dollar amount; with Stripe connected (US businesses) the customer pays it by card as they approve.

Putting the patch on the quote

In MakeHay, the asphalt paving starter list carries "Hot mix asphalt, per ton" as an Each item, "Base repair, full depth" and "Mill and fill" as Per square foot lines, and "Grading and compaction" and "Trucking and mobilization" as Flat price lines in the price book; a flat minimum is its own line, and per-ton is an Each line, not a special unit. The parking lot maintenance demo invoice bills 64 sq ft of pothole repair with hot mix per square foot.
