🛣️ Asphalt Tonnage & Cost Calculator

How the Asphalt Tonnage Formula Works

Asphalt is sold by the ton, but you measure your driveway in square feet. The conversion runs through density: compacted hot mix asphalt weighs roughly 145 pounds per cubic foot (about 2 tons per cubic yard).

The formula: Length (ft) × Width (ft) × (Thickness in inches ÷ 12) × 145 ÷ 2,000 = Tons.

A quick shortcut used by paving crews: at 1 inch of compacted thickness, one ton of hot mix covers about 160 square feet. At the standard 3-inch driveway thickness, that drops to roughly 53 square feet per ton.

How Thick Should Asphalt Be?

• Overlay / resurfacing (existing asphalt): 1.5 to 2 inches of new hot mix over a sound existing surface.
• New residential driveway: 2 to 3 inches of compacted hot mix over a 6 to 8-inch compacted gravel base. The base does most of the structural work — never skip it.
• Heavy vehicles / RV pads: 3 to 4 inches of asphalt over an 8-inch base.
• Full-depth asphalt (no gravel base): 4 to 6 inches — used where excavation is limited, but generally more expensive than asphalt-over-gravel.

Hot Mix vs. Cold Patch vs. Millings

• Hot Mix Asphalt (HMA): The real thing — delivered at 300°F and rolled by a crew. It is what every proper driveway, road, and parking lot is made of. Not DIY-friendly: it must be placed and compacted before it cools.
• Cold Mix / Cold Patch: Bagged asphalt for pothole repairs and small patches. Convenient but far weaker than hot mix — use it for repairs, not full surfaces.
• Recycled Asphalt Millings: Ground-up old asphalt. At $10–$30 per ton it is a budget-friendly driveway surface that re-binds slightly in hot weather, landing somewhere between gravel and pavement in performance.

What Does Asphalt Cost in 2026?

• Hot mix material only: roughly $100–$160 per ton depending on region and oil prices.
• Installed (contractor): most residential driveways run $5–$8 per square foot including base work, which is why a typical two-car driveway lands between $4,000 and $8,000.
• Millings: $10–$30 per ton material, $2–$5 per square foot installed.

Frequently Asked Questions

How many tons of asphalt are in a cubic yard?

Compacted hot mix asphalt weighs about 2 tons (4,050 lbs) per cubic yard at 145 lb/ft³. Loose (uncompacted) mix is lighter, around 1.6–1.8 tons per cubic yard.

How much area does a ton of asphalt cover?

At 1 inch compacted thickness, about 160 sq ft. At 2 inches, 80 sq ft. At 3 inches (standard driveway), roughly 53 sq ft per ton.

Can I pave an asphalt driveway myself?

Hot mix asphalt is not a DIY material — it arrives at 300°F and must be spread and rolled within minutes. DIY options are recycled millings or a gravel driveway. The gravel base prep, however, is very DIY-able and can cut your contractor quote.

Is asphalt cheaper than concrete?

Yes, upfront. Asphalt runs $5–$8 per square foot installed vs. $8–$12 for concrete. Concrete lasts longer and needs less maintenance, so lifetime costs are closer than they look. See our full comparison.

How thick should the gravel base under asphalt be?

6 to 8 inches of compacted crushed stone for a residential driveway. Use our Gravel Calculator to size the base layer.
