What an asphalt driveway costs: worked national example
A 40 × 20 ft driveway (800 sq ft) paved 3" thick in hot mix, at national baseline pricing — not adjusted for any region. Enter your own dimensions below for a figure matched to your project and ZIP code.
That driveway takes 14.50 tons of mix in place, 15.23 tons ordered once the standard 5% waste is added, arriving on 1 truckload — an all-in $276 per ton placed.

Typical Asphalt Costs by Thickness
| Thickness / Use | $/sq ft Installed | Tons per 1,000 sq ft | Typical Application |
|---|---|---|---|
| 2" Overlay | $2.50 – $5.00 | 12.1 tons | Resurfacing existing pavement |
| 3" Residential | $3.50 – $7.00 | 18.1 tons | Driveways, walkways |
| 4" Heavy residential | $4.50 – $9.00 | 24.2 tons | Driveways with heavy vehicles |
| 5" Commercial | $5.50 – $11.00 | 30.2 tons | Parking lots, light commercial |
| 6" Heavy traffic | $7.00 – $14.00 | 36.3 tons | Truck routes, loading docks |
Installed costs include material, labor, and standard base prep. Tonnage is the mix in place before the waste allowance. Removal, drainage and striping are priced as separate lines in Professional mode and are not in these rates.
Assumptions & Sources
Assumptions
- Pricing basis: The free estimate prices paving all-in by the square foot for the thickness you pick, not by the ton. On the 40 x 20 ft reference driveway that works out to $276 per ton of mix placed, which already carries the crew, the roller and standard base prep.
- Weight conversion: Hot mix asphalt weighs 145 lbs/cu ft, which is 0.006042 tons per square foot per inch of depth. A 3" residential driveway therefore uses 18.1 tons per 1,000 sq ft in place.
- Waste factor: 5% standard waste included for edge trimming, machine startup/shutdown, and irregular shapes.
- Labor: Paving labor — screed operator, roller operator, rakers — is inside the per-square-foot rate rather than quoted separately. Base prep labor varies with site condition and is a separate line in Professional mode.
- Regional multiplier: ZIP-code-based adjustment using BLS regional wage data and published construction cost indices applied to both materials and labor.

Pro Tips from the Field
- Base prep is 90% of the job: If the gravel base isn't graded and compacted right, the surface will rut and crack within two years. Don't let anyone pave over soft spots — pull them out and rebuild with clean crushed stone.
- Compaction timing is everything: Hot mix has a narrow window — once it drops below 185°F, the roller can't densify it properly. Good crews pave in warm weather (50°F+) and work fast. Cold patches are band-aids, not repairs.
- Spec the right thickness: Driveways need 2-3", parking lots 3-4", and anything with truck traffic needs 4-6". Under-spec the thickness and you'll be repaving in 5 years instead of 15.
- Sealcoat on schedule, not early: Wait 6-12 months for new asphalt to fully cure, then sealcoat every 2-3 years. It costs a small fraction of a repave per square foot and extends pavement life substantially. This calculator does not price sealcoating — get it quoted separately rather than budgeting from a number we have no model for.
- Compare bids by tonnage: Get at least three bids and ask each contractor about tonnage, not just square footage. The guy quoting by area might be planning a thinner lift. Tonnage tells you exactly how much material is going down.

How Asphalt Paving Is Priced
Asphalt is quoted two ways and the two rarely agree. Contractors bid by the square foot; suppliers sell by the ton. This calculator prices by the square foot for the thickness you choose — all-in, covering material, the paving crew and standard base prep — and separately reports the tonnage so you can check a bid against it. On the 40 x 20 ft reference driveway at 3" that is $5.00 per square foot, or $4,000 for the job.
Always compare bids by tonnage rather than area. A contractor quoting a lower price per square foot may simply be planning a thinner lift, and thickness is the whole ballgame for how long the pavement lasts. The arithmetic is fixed: hot mix weighs 145 pounds per cubic foot, so one square foot at one inch of depth is 0.006042 tons. The reference driveway needs 14.50 tons in place and 15.23 tons ordered, once the 5% waste allowance for edge trimming and machine start-up is added.
What the free estimate does not price: tearing out the old surface, excavating and rebuilding a failed base, drainage structures, striping and sealcoating. Those are separate lines in Professional mode, and on a resurfacing job the removal alone can move the number materially. If your existing driveway is cracked through to the base, price a rebuild rather than an overlay — a new lift over a broken base reflects every crack back through within two winters.
Asphalt Cost by Thickness on a 40 x 20 ft Driveway
Thickness is the one specification input the free calculator gives you, and it is the one that decides whether the driveway lasts five years or twenty. Every row is a separate execution of the estimate on the same 800 square foot driveway.
| Thickness | Tons in place | Tons ordered | Truckloads | Installed cost | Per sq ft | Per ton placed |
|---|---|---|---|---|---|---|
| 2" Overlay | 9.67 | 10.15 | 1 | $2,800 | $3.50 | $290 |
| 3" Residential | 14.50 | 15.23 | 1 | $4,000 | $5.00 | $276 |
| 4" Heavy residential | 19.33 | 20.30 | 1 | $5,200 | $6.50 | $269 |
| 5" Commercial | 24.17 | 25.38 | 2 | $6,400 | $8.00 | $265 |
| 6" Heavy traffic | 29.00 | 30.45 | 2 | $8,000 | $10.00 | $276 |
Read the per-ton column carefully: it falls from $290 at 2" to a low of $265 at 5", then rises again at the top of the range. That is not a mistake in the arithmetic. The square-foot ladder is not linear in thickness: mobilisation, screed setup and rolling cost the same whatever depth you lay, so they spread over more tonnage as the lift thickens — until the heaviest sections, where the rate steps up for the extra passes and the compaction a truck-rated section needs.
Asphalt Cost by Driveway Size
The per-square-foot rate does not fall with scale in this estimate — a 5,000 square foot lot pays the same rate as a one-car pad. What does change is the logistics: a paving crew that can lay the whole job in one continuous pull produces a better surface than one that has to cold-joint it, and tonnage is what tells you which you are buying.
| Area | Square feet | Tons ordered | Truckloads | Installed cost | Per sq ft |
|---|---|---|---|---|---|
| 20 × 10 ft | 200 | 3.81 | 1 | $1,000 | $5.00 |
| 30 × 12 ft | 360 | 6.85 | 1 | $1,800 | $5.00 |
| 40 × 20 ft | 800 | 15.23 | 1 | $4,000 | $5.00 |
| 50 × 20 ft | 1,000 | 19.03 | 1 | $5,000 | $5.00 |
| 60 × 24 ft | 1,440 | 27.40 | 2 | $7,200 | $5.00 |
| 100 × 50 ft | 5,000 | 95.16 | 5 | $25,000 | $5.00 |
Asphalt Cost by Metro Area
Hot mix has to arrive above 250°F and be compacted before it drops below 185°F, so the haul from the plant is a hard constraint rather than a line item — which is why paving prices track local plant density and crew rates more than they track the oil market. These are the complete regional factors this calculator applies, not a selection. Type the ZIP in the second column into the ZIP field above and the calculator will price your own driveway at that factor. The cost column is the same 40 x 20 ft reference driveway, so the rows are comparable to each other and to the national $4,000 above.

Frequently Asked Questions
Construction Cost Estimation FAQs
A 40 by 20 foot driveway — 800 square feet — paved 3 inches thick comes to $4,000 installed at national baseline pricing, in a band of $2,800 to $5,600. That is $5.00 per square foot typical, $3.50 to $7.00 across the band. Thinner and thicker sections move it: 2 inches at $3.50 per square foot, 3 inches at $5.00 per square foot, 4 inches at $6.50 per square foot, 5 inches at $8.00 per square foot, 6 inches at $10.00 per square foot. The rate covers material, the paving crew and standard base prep; it does not cover tearing out an old surface, drainage or striping.
Hot mix weighs 145 pounds per cubic foot, so one square foot at one inch of depth is 0.006042 tons. A 3 inch lift therefore needs 18.1 tons per 1,000 square feet in place. The 40 x 20 ft reference driveway takes 14.50 tons in place and 15.23 tons ordered once the 5 percent waste allowance is added — 1 truckload. Put another way, one ton covers about 55 square feet at 3 inches.
Two inches is a resurfacing lift over sound pavement, not a driveway in its own right. Three inches is the residential standard, four if you park anything heavy, and five to six for trucks and loading docks. On the 40 x 20 ft reference driveway this calculator prices 2 inches at $2,800 and 6 inches at $8,000 — a spread of $5,200. Under-specifying the lift is the most expensive saving in paving: you will repave in five years rather than fifteen, and the second job includes removing the first.
Read this figure carefully, because it is not a supplier's mix price. Dividing the whole installed cost by the tonnage placed, this calculator works out at $290 per ton at 2 inches down to $265 per ton at 5 inches, on the 40 x 20 ft reference driveway. The figure falls as the lift thickens because mobilisation, screed setup and rolling cost the same whatever depth you lay. A supplier quoting you a mix price per ton is quoting a different, much smaller number — the mix on a truck, with no crew attached.
On paper, yes: this calculator prices a 2 inch overlay on the reference driveway at $2,800 against $4,000 for a 3 inch section, a saving of $1,200. In practice it only holds if the base underneath is sound. An overlay laid over a cracked, pumping base reflects every one of those cracks back through the new surface within two winters, and then you pay for removal on top of a second repave. Dig a test hole before you decide. This estimate does not price removal or base rebuilding — those are Professional-mode lines.
This calculator carries 28 metro factors. The same 40 x 20 ft reference driveway runs $6,800 in San Francisco Bay Area, CA at 1.70x and $3,600 in Indianapolis, IN at 0.90x, against $4,000 at the national baseline. Hot mix has to reach the site above 250 degrees and be rolled before it drops below 185, so the haul from the plant is a hard constraint — paving prices track local plant density and crew rates more than they track the oil market. The table on this page lists every metro with a ZIP you can type into the calculator.
Fifteen to twenty years, given a properly compacted base and maintenance. Sealcoat once the surface has cured — six to twelve months after paving, not before — then every two to three years, and fill cracks as soon as they open rather than at the end of the season. Water getting under the pavement through an unfilled crack is what destroys the base, and once the base goes the surface goes with it. This calculator does not price sealcoating or crack filling.
