| Thickness | Tons | Tons +5% |
|---|---|---|
| 1.5 in | 12.7 | 13.3 |
| 2 in | 16.9 | 17.8 |

How the numbers are built
- 1,400 sq ft × (2 ÷ 12) ft = 233 cubic feet at 2 inches.
- × 145 lb = 33,833 lb.
- ÷ 2,000 = 16.9 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.
What size job this is
This is a large residential driveway or a small commercial lot. Most homeowners land between 2 and 3 inches compacted.
Trucks and ordering
At 3 inches, 25.4 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
Good uses:
- 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
Less suited to:
- 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 8x16 area at 4 inches takes about 3.2 tons.
- Weight used here: about 2.0 tons per cubic yard (roughly 145 lb per compacted cubic foot).
Common estimating mistakes
- Skipping drainage. Water sitting under any surface softens the base and leads to ruts and potholes.
- Ordering exactly the math. Uneven ground and spillage nearly always need a little more than the flat calculation.
- Assuming every supplier uses the same weight. Two yards selling the same product name can quote different tons per yard.
- Using inches as if they were feet. Depth has to be divided by 12 before you multiply; skipping that step inflates the order twelvefold.
