| Thickness | Square feet | Square yards |
|---|---|---|
| 1.5 in | 3,090 | 343 |
| 2 in | 2,317 | 257 |

The math
- 28 tons × 2,000 = 56,000 lb.
- ÷ 145 lb per cu ft = 386.2 cu ft.
- ÷ (2 ÷ 12) ft = 2,317 sq ft at 2 inches.
Sizing it up
1,545 square feet is about a 39 by 39 foot square, or a 12-foot-wide strip about 129 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: 28 tons is about 2 typical tandem loads.

Good and poor uses for asphalt
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
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).
Common estimating mistakes
- Assuming every supplier uses the same weight. Two yards selling the same product name can quote different tons per yard.
- Measuring only the main rectangle. Aprons, turnouts and curved edges add real square footage.
- Skipping drainage. Water sitting under any surface softens the base and leads to ruts and potholes.
- Using inches as if they were feet. Depth has to be divided by 12 before you multiply; skipping that step inflates the order twelvefold.
