| Thickness | Tons | Tons +5% |
|---|---|---|
| 1.5 in | 29.5 | 30.9 |
| 2 in | 39.3 | 41.2 |
| 2.5 in | 49.1 | 51.5 |
| 3 in | 58.9 | 61.9 |
| 4 in | 78.5 | 82.5 |
How the numbers are built
- 3,250 sq ft × (2 ÷ 12) ft = 542 cubic feet at 2 inches.
- × 145 lb = 78,542 lb.
- ÷ 2,000 = 39.3 tons.
A shortcut: each inch of compacted asphalt over 1,000 square feet weighs about 6 tons. See tons of asphalt per 1,000 square feet.
Putting the area in context
This is a large residential driveway or a small commercial lot. A compacted stone base under the asphalt is ordered separately.
Trucks and ordering
At 3 inches, 58.9 tons is about 5 truckloads at around 14 tons each. Plants set minimum orders and charge for hauling; see asphalt hauling cost per ton.
Things that move the total
- Mix density typically runs 140 to 150 lb per cubic foot.
- Base condition: dips and ruts fill with extra mix.
- Waste of 5 to 10 percent is a common allowance.

Where asphalt fits
Works well for:
- Driveways, parking pads and private lanes that need a smooth, sealed surface
- Overlays on old pavement that is cracked but still structurally sound
- Areas where snow will be plowed, since a paved surface does not throw stone
Poor fit for:
- Ground that stays soft or wet, unless the base and drainage are fixed first
- Very small patches, where bagged cold patch is often simpler
- Jobs in cold weather, since hot mix needs warm temperatures to compact properly
Quick reference numbers
- Per inch over 100 sq ft: about 0.62 tons of asphalt (0.31 cubic yards).
- Per inch over 1,000 sq ft: about 6.2 tons.
- Another size for comparison: a 20x25 area at 4 inches takes about 12.3 tons.
- Weight used here: about 2.0 tons per cubic yard (roughly 145 lb per compacted cubic foot).
Common estimating mistakes
- Using inches as if they were feet. Depth has to be divided by 12 before you multiply; skipping that step inflates the order twelvefold.
- Ignoring the base. A thin surface layer over soft soil fails early no matter how much material is on top.
- Skipping drainage. Water sitting under any surface softens the base and leads to ruts and potholes.
- Measuring only the main rectangle. Aprons, turnouts and curved edges add real square footage.
