| Thickness | Tons | Tons +5% |
|---|---|---|
| 1.5 in | 16.3 | 17.1 |
| 2 in | 21.8 | 22.8 |

How the numbers are built
- 1,800 sq ft × (2 ÷ 12) ft = 300 cubic feet at 2 inches.
- × 145 lb = 43,500 lb.
- ÷ 2,000 = 21.8 tons.
Quick check: about 0.006 tons per square foot per inch. 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. Overlays often run 1.5 to 2 inches; new work 2 to 3 inches.
Trucks and ordering
At 3 inches, 32.6 tons is about 3 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
Best suited to:
- 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 3 inches takes about 2.4 tons.
- Weight used here: about 2.0 tons per cubic yard (roughly 145 lb per compacted cubic foot).
Common estimating mistakes
- Ordering exactly the math. Uneven ground and spillage nearly always need a little more than the flat calculation.
- 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.
- Mixing up cubic yards and tons. Yards are volume, tons are weight; convert with the product’s weight per yard.
