How the asphalt calculation works
Volume = length × width × thickness
Convert thickness to feet first. A 50 × 12 ft driveway at 3 inches is 50 × 12 × 0.25 = 150 cubic feet.
Tons = cubic feet × density ÷ 2,000
At a typical 145 lb per cubic foot, 150 cu ft weighs 21,750 lb, which is 10.88 tons.
Add waste for edges and uneven base
5% is common for a well-graded base. 10.88 tons becomes 11.42 tons.
Price the job: asphalt + crew + equipment, then markup
Cost the asphalt per ton, add crew hours and equipment, and apply your markup on the total.
Worked example. A 50 × 12 ft driveway at 3 inches compacted is 150 cu ft. At 145 lb/cu ft that is 10.88 tons, or 11.42 tons with 5% waste. At $115 a ton the asphalt costs $1,313.16. With 10 crew hours at $65 and $400 of equipment the cost is $2,363.16, and a 30% markup prices the job at $3,072.10.
Asphalt FAQ
How many tons of asphalt do I need?
Multiply length × width × thickness in feet, then by about 145 lb per cubic foot, and divide by 2,000. A 600 sq ft driveway at 3 inches needs about 10.9 tons before waste.
How much does a ton of asphalt cover?
At 145 lb/cu ft, one ton covers about 80 sq ft at 2 inches or about 55 sq ft at 3 inches.
How thick should an asphalt driveway be?
Residential driveways are usually 2–3 inches of compacted asphalt over a compacted gravel base. Heavier traffic and commercial lots need more.
How do I estimate the cost of an asphalt driveway?
Multiply the tons by the delivered price per ton, then add labor, equipment and your markup. This calculator does all three.
What does an asphalt driveway cost per square foot?
Divide the job price by the area. In the example above, a 600 sq ft driveway priced at $3,072.10 is about $5.12 per sq ft, with asphalt at $115 a ton, a 3-inch layer, crew, equipment and a 30% markup. Your local asphalt price and base work change it most.
What is the density of asphalt?
Compacted hot mix asphalt is typically around 145 lb per cubic foot, but mixes vary, so use the figure from your plant if you have it.
