How Much Does 50 Tons of Asphalt Cover?
How much does 50 tons of asphalt cover: about 4,138 square feet at 2 inches compacted and about 2,759 square feet at 3 inches, using 145 pounds per cubic foot. A thicker new surface covers less.
Asphalt tonnage calculator →Coverage by thickness
| Thickness | Square feet | Square yards |
|---|---|---|
| 1.5 in | 5,517 | 613 |
| 2 in | 4,138 | 460 |
| 2.5 in | 3,310 | 368 |
| 3 in | 2,759 | 307 |
| 4 in | 2,069 | 230 |
The math
- 50 tons × 2,000 = 100,000 lb.
- ÷ 145 lb per cu ft = 689.7 cu ft.
- ÷ (2 ÷ 12) ft = 4,138 sq ft at 2 inches.
In driveway terms
2,759 square feet is about a 52 by 52 foot square, or a 12-foot-wide strip about 230 feet long at 3 inches. That is a large drive or a small lot.
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: 50 tons is about 4 typical tandem loads.

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
Think twice 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 8x16 area at 2 inches takes about 1.6 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.
- Assuming every supplier uses the same weight. Two yards selling the same product name can quote different tons per yard.
- Forgetting that compaction shrinks loose material. A loose 4-inch spread of a dense-graded stone may finish closer to 3 inches after rolling.
- Skipping drainage. Water sitting under any surface softens the base and leads to ruts and potholes.
