Asphalt Calculator — Tons for a Driveway
Who this is for: For paving crews and homeowners speccing a driveway resurfacing — how many tons of hot mix the job takes and what the material will run at 2026 plant prices.
Driveway area and thickness in — hot-mix tons out, with a $130-220/ton cost band and the 2-inch vs 3-inch driveway thickness reality check.
Quick answer: Tons = area (sf) × thickness (in) × 0.00604. A 12×40 driveway at 3 inches ≈ 8.7 tons (9.1 with waste) — $1,200-2,000 of hot mix at 2026 material prices.

How does the asphalt calculator convert to tons?
Hot-mix asphalt runs about 145 pounds per cubic foot compacted, so tons = area (sf) × thickness (in) ÷ 12 × 145 ÷ 2,000 — the calculator adds your waste factor and prices the result at a $130-220 per ton material band (2026 national plant ballpark; small residential loads often carry minimum-load charges). Thickness is where driveway jobs go wrong: 2 inches compacted is a common resurfacing minimum, 3 inches is the standard for a new residential driveway carrying cars, and anything regularly parked on by trucks wants 4+ inches over proper base. A 12 × 40 driveway at 3 inches is 480 sf × 0.25 ft = 120 cf ≈ 8.7 tons — 9.1 with 5% waste — a truckload and change.
