How Much Does 7 Tons of Asphalt Cover?
How much does 7 tons of asphalt cover: about 579 square feet at 2 inches compacted and about 386 square feet at 3 inches, using 145 pounds per cubic foot. The thickness choice changes coverage more than anything else.
Asphalt tonnage calculator →Coverage by thickness
| Thickness | Square feet | Square yards |
|---|---|---|
| 1.5 in | 772 | 86 |
| 2 in | 579 | 64 |
| 2.5 in | 463 | 51 |
| 3 in | 386 | 43 |
| 4 in | 290 | 32 |
The math
- 7 tons × 2,000 = 14,000 lb.
- ÷ 145 lb per cu ft = 96.6 cu ft.
- ÷ (2 ÷ 12) ft = 579 sq ft at 2 inches.
In driveway terms
386 square feet is close to a 19 by 19 foot square, or a 12-foot-wide strip about 32 feet long at 3 inches. That is typical of a residential driveway.
Things to keep in mind
- Density varies from about 140 to 150 lb per cubic foot by mix.
- Waste and base dips use 5 to 10 percent more.
- Truck loads: 7 tons is under one typical tandem load.

When to choose 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 10x20 area at 4 inches takes about 4.9 tons.
- Weight used here: about 2.0 tons per cubic yard (roughly 145 lb per compacted cubic foot).
Mistakes that throw off the order
- Using inches as if they were feet. Depth has to be divided by 12 before you multiply; skipping that step inflates the order twelvefold.
- Ordering exactly the math. Uneven ground and spillage nearly always need a little more than the flat calculation.
- 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.
