Asphalt Driveway Calculator

Estimate the tons of asphalt needed for a driveway or paved area.

How this is calculated
Volume (cu ft) = L × W × (Thickness ÷ 12); Tons = Volume × 145 lb/cu ft ÷ 2000

Assumptions used in this calculation

  • Standard density: Assumes a standard hot-mix asphalt density of 145 lb per cubic foot, actual mix density varies by supplier.

About this calculator

The asphalt driveway calculator finds the volume of a paved area from length, width and thickness, then converts it to tons using standard hot-mix asphalt density, the unit asphalt suppliers price and deliver by.

Worked example

40ft × 12ft driveway, 3in thick

Result: ≈ 8.7 tons
