Asphalt Overlay Cost: Resurfacing a Parking Lot or Driveway

The table below is the short answer. It gives 2026 national planning ranges per square foot by scope, with the variable most likely to push a specific project to one end of its range.

Two lots with the same square footage can land at opposite ends of the same row. Area sets the order of magnitude; condition, access, and scope set the number.

Resurfacing and overlay describe the same work with different vocabularies. An overlay is a new layer of asphalt placed over the existing surface, and resurfacing is what most property owners call it. Contractors and specifications tend to say overlay; consumer cost guides tend to say resurfacing.

The words matter in one place only: a quote for resurfacing that does not say how thick the new layer is, and whether anything is being milled off first, is not a comparable number. Ask for compacted thickness and milling depth in writing regardless of which word the proposal uses.

For a commercial lot on sound pavement, plan on $2.00 to $5.00 per square foot for a straight overlay and $4.00 to $9.00 where the surface is milled first. The low end of each range belongs to large, open, single-phase lots. The high end belongs to occupied sites that have to stay partly in use.

Three things move a commercial number more than material price does. Phasing is first: a lot that must be paved in sections at night, with traffic control and repeated mobilization, can cost half again what the same area costs in one closure. Second is everything the new elevation touches — manholes and valve boxes have to be raised, curb reveal shrinks, and accessible parking slopes have to still comply once the surface is higher. Third is failed area: structurally failed sections need full-depth repair before the overlay, and that is priced separately.

For the wider maintenance budget an overlay sits inside, see parking lot maintenance cost.

Residential overlays run higher per square foot than commercial ones, typically $2.50 to $6.00, and the reason is arithmetic rather than quality. Mobilizing a crew, a truck of hot mix, and a roller costs roughly the same whether the job is 600 square feet or 6,000. On a small driveway that fixed cost is spread over very little area.

Expect a minimum job charge on anything under roughly 1,000 square feet. On a genuinely small driveway the minimum, not the per-foot rate, is often the price. That is also why per-square-foot quotes for small residential work vary so much between contractors: they are quoting the same job with the fixed cost allocated differently.

Ranges are hard to picture. These are the same brackets applied to three sizes people actually ask about, with the assumptions stated so you can adjust them.

None of these includes full-depth repair, drainage correction, or striping, all of which are normally separate. Measure before you apply them — use the Parking Lot Square Footage Calculator if you do not have a number yet.

Milling grinds off part of the existing surface before the new layer goes down. It adds roughly $1.00 to $2.50 per square foot, and there are situations where skipping it is not a saving but a defect.

The related trap is drainage. An overlay follows the grade it is placed on, so a lot that ponds water today will pond in the same places afterward, just two inches higher. Milling can correct a shallow low spot; it cannot fix a grading problem. See how drainage affects pavement.

The single biggest source of apparent price differences between overlay proposals is scope, not rate. These items are frequently excluded from the headline number.

Two bids that look $20,000 apart are often the same work with different exclusions. How to Compare Asphalt Paving Bids walks through normalizing them.

An overlay is typically a third to a half the cost of full removal and replacement, which runs roughly $7.00 to $15.00 per square foot. That gap is the entire reason overlays get specified, and it is only a saving when the overlay actually lasts.

The honest framing is cost per year of service, not cost per square foot. An overlay over sound pavement is inexpensive and buys real years. An overlay over a failing base is cheaper on day one and can be cracking again within a season or two, at which point the money is gone and the replacement still has to happen.

Use the Repair vs Replace Calculator to work the comparison on your own numbers, and Asphalt Paving vs Asphalt Overlay for the condition side of the decision.

Overlays are commonly placed at 1.5 to 2 inches compacted, with 2 inches typical on commercial lots and heavier sections used where trucks turn. Thickness is stated compacted, not loose, and the difference is not cosmetic — loose asphalt compacts down meaningfully, so a proposal quoting loose depth is quoting less pavement than it appears to.

Material scales close to linearly with thickness while mobilization, traffic control, and prep do not, so going from 1.5 to 2 inches adds less than a third to the total even though it is a third more asphalt. That asymmetry is why shaving thickness is usually a poor place to find savings: you give up a disproportionate share of the service life for a small share of the price.

For the structural side of thickness, see asphalt paving thickness for parking lots, and use the Asphalt Tonnage Calculator to convert area and depth into tons.

If you search for overlay costs you will eventually find a government figure far below any quote you have received, and it is worth understanding why rather than taking it to a contractor.

A Federal Highway Administration technical report puts the total cost of milling and overlay — milling, tack, placement, and traffic control — at about $8.00 per square yard for a 1.5-inch overlay and $11 to $12 per square yard at 2 to 2.5 inches. Those figures rest on a cost basis from roughly 2013. Escalating them by the U.S. Bureau of Labor Statistics producer price index for asphalt paving mixture and block manufacturing, which has risen about 38% from a 2013 annual average of 319.1 to 440.7 in July 2026, puts the 1.5-inch figure near $11 per square yard and the 2-inch figure near $15 to $17 per square yard — roughly $1.20 to $1.85 per square foot.

That is still well below the retail brackets on this page, and the difference is real rather than a markup. Agency work is bid at enormous volume with mobilization spread across miles of roadway, not one parking lot. It carries no retail overhead. And a materials index understates the escalation of a price that is substantially labor, so treat the converted figure as a floor rather than a target.

Cost pages go stale quickly, and a number without a method is not verifiable. These ranges were reviewed in September 2026 against several independent kinds of evidence rather than a single source.

The BLS producer price index for asphalt paving mixture and block manufacturing stood at 440.7 in July 2026 against 411.8 in July 2025, about 7% higher year over year, though below the 451 it reached in January. Published state DOT asphalt indices, which are used for contract price adjustments rather than as retail quotes, sat in September 2026 at $807.50 per ton in Maryland, $715.00 for PG 64-22 in New Jersey, and $714 per ton in Georgia — the Georgia figure up from $559 in March. The Caltrans contract cost database, which holds more than three million bid line items and was current to bid openings in late August 2026, supplies real competitively bid unit prices. National consumer and commercial cost guides were read together to bracket installed pricing rather than relied on individually.

Two distinctions run through all of it. Material price is not installed price: an index or plant quote covers hot mix, while an installed price covers labor, equipment, trucking, mobilization, disposal, restoration, overhead, and profit. And agency unit prices are not private commercial prices, for the reasons in the section above.

No national figure predicts an individual project, and this guide deliberately does not publish location-specific prices, because a defensible local number needs local evidence. Treat everything here as a planning bracket and let proposals set the price.

An overlay adds surface, not support. Where the problem is underneath, a new layer inherits it — and the cost of finding that out is the whole overlay, not the difference between scopes.

Diagnose before pricing. What causes alligator cracking covers the most common disqualifying condition, and a pavement condition rating gives you a defensible read before you request bids.
