How to Calculate Asphalt Tonnage
Asphalt quantity is ordered by the ton. Hot mix asphalt (HMA) weighs approximately 145 lbs per cubic foot, or about 2 tons per cubic yard. The formula:
Cubic Feet = Length × Width × (Depth ÷ 12) Cubic Yards = Cubic Feet ÷ 27 Tons = Cubic Yards × 2
Recommended Asphalt Depth by Project
| Project Type | Depth | Notes |
|---|---|---|
| Residential driveway | 2–3 inches | Light vehicle traffic |
| Parking lot | 3–4 inches | Standard commercial use |
| Heavy traffic road | 4–6 inches | Trucks and buses |
| Overlay / resurface | 1.5–2 inches | Over existing base |
Asphalt Cost per Ton
Hot mix asphalt typically costs $80–$150 per ton depending on region and oil prices. A standard 500 sq ft driveway at 3" depth requires about 9–10 tons, costing roughly $900–$1,500 in materials alone. Installation labor typically adds $2–$5 per square foot.

Frequently Asked Questions
How many tons of asphalt do I need for a driveway?+
A standard single-car driveway (10 ft × 50 ft) at 3-inch depth needs about 5.5 cubic yards or roughly 11 tons of asphalt. A 2-car driveway (20 ft × 50 ft) at 3 inches requires about 22 tons.
How thick should an asphalt driveway be?+
Residential driveways should be at least 2–3 inches of compacted asphalt over a 4–6 inch compacted aggregate base. Heavier use areas or cold climates may require 3–4 inches of asphalt. Always compact the base layer before paving.
How much does asphalt cost per square foot?+
Asphalt paving typically costs $3–$7 per square foot installed, including materials and labor. Material alone (hot mix asphalt) runs $80–$150 per ton. A 1,000 sq ft driveway typically costs $3,000–$6,000 fully installed.
How long does an asphalt driveway last?+
A properly installed and maintained asphalt driveway lasts 20–30 years. Sealcoat every 3–5 years to protect against UV damage, oil spills, and water penetration. Fill cracks as they appear to prevent water infiltration and base damage.
