Tons of Asphalt for 900 Square Feet
Tons of asphalt for 900 square feet: about 10.9 tons at 2 inches compacted and about 16.3 tons at 3 inches, figured at roughly 145 pounds per cubic foot. That is 100 square yards of pavement.

| Thickness | Tons | Tons +5% |
|---|---|---|
| 1.5 in | 8.2 | 8.6 |
| 2 in | 10.9 | 11.4 |
| 2.5 in | 13.6 | 14.3 |
| 3 in | 16.3 | 17.1 |
| 4 in | 21.8 | 22.8 |
How the numbers are built
- 900 sq ft × (2 ÷ 12) ft = 150 cubic feet at 2 inches.
- × 145 lb = 21,750 lb.
- ÷ 2,000 = 10.9 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
An area this size is a typical one- or two-car residential driveway. Overlays often run 1.5 to 2 inches; new work 2 to 3 inches.
Trucks and ordering
At 3 inches, 16.3 tons is about 2 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.

Good and poor uses for asphalt
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).
Where estimates go wrong
- Ordering exactly the math. Uneven ground and spillage nearly always need a little more than the flat calculation.
- Forgetting that compaction shrinks loose material. A loose 4-inch spread of a dense-graded stone may finish closer to 3 inches after rolling.
- Measuring only the main rectangle. Aprons, turnouts and curved edges add real square footage.
- Using inches as if they were feet. Depth has to be divided by 12 before you multiply; skipping that step inflates the order twelvefold.
