Asphalt Calculator
Driveway or parking-lot tons from square footage and mat thickness. Distinct from an asphalt driveway cost estimate. Click any i for detail.

Thickness
Compacted mat. Driveways are often 2–3 in over base. |

Density (lb/ft³)

Density
Hot-mix midpoint is often ~145 lb/ft³. Confirm with your plant. |
How to use this calculator
- Enter paved area.
- Enter compacted thickness.
- Adjust density if your plant gave a number.
- Read tons and cubic yards.
Results explained
Volume comes from area × thickness. Tons use density. Cost per ton and labor live on the driveway cost page.
Quick reference: asphalt
Quantity, not price.
| Item | Detail |
|---|---|
| Typical HMA density | ~140–150 lb/ft³ |
| 1 ton at 3 in | ≈ 55 sq ft |
| 1 ton at 2 in | ≈ 83 sq ft |
| Cubic yards | cu ft ÷ 27 |
Order extra for joints, waste, and compaction.
How the estimate is built
cu ft = sq ft × (thickness in ÷ 12). tons = (cu ft × density) ÷ 2000.
Example scenario
600 sq ft × 3 in at 145 lb/ft³ ≈ 10.9 tons (2.8 yd³).
FAQ
Is this the driveway cost calculator?
No. This is tons/yards. Cost is a separate page.
Why isn’t my plant’s tonnage matching?
Density, compacted vs loose, and waste differ. Use their factor.
Gravel base?
Not included. Base is a separate cubic-yard takeoff.
