Asphalt Calculator
Estimate asphalt tonnage for driveways, parking areas and paths.
You need approximately
14.5 tons
- Recommended with 5% waste
- 15.23 tons
- Area
- 800 sq ft
- Volume
- 7.41 cu yd
How we calculate this
Asphalt tonnage = area × thickness (converted to feet) × density, using an industry average of about 145 lbs per cubic foot for compacted hot mix asphalt, then converted to tons (÷ 2,000 lbs).
Example
Measuring tips
Residential driveways typically use 2–3 inches of asphalt over a compacted gravel base; parking areas and roads often use 3–4 inches or more for durability.
Common mistakes
- Ordering asphalt by cubic yards when suppliers price and deliver by the ton.
- Skipping a proper gravel base, which is separate from the asphalt layer itself.
- Underestimating thickness for areas with vehicle or heavy equipment traffic.
Frequently asked questions
How many tons of asphalt do I need per square foot?
At 2 inches thick, roughly 0.06 tons per square foot; more for thicker applications — use the calculator above for your exact dimensions.
What thickness should a driveway be?
2–3 inches is standard for residential driveways; commercial areas typically use 3–4 inches or more.
