Enter your driveway or lot dimensions and get a quick estimate of the square yards and tons of asphalt required. No email, no signup, just the numbers.
Quick answer: to use an asphalt calculator, enter the length and width of the area in feet and the asphalt thickness in inches. The tool multiplies them into cubic feet, then converts to square yards of coverage and tons of hot-mix asphalt (about 145 pounds per cubic foot compacted).
Asphalt Calculator
How the Calculation Works
Asphalt is estimated by volume, then converted to weight. The steps are simple:
- Area: length times width gives square feet. Divide by 9 for square yards.
- Volume: area times the thickness (converted from inches to feet) gives cubic feet.
- Weight: compacted hot-mix asphalt weighs roughly 145 pounds per cubic foot, so cubic feet times 145 gives pounds. Divide by 2,000 for tons.
The calculator above does all of this for you. It is a planning estimate, real jobs include a little extra for waste and compaction.
Key Takeaways
- You need length, width, and thickness to estimate asphalt.
- Square yards measure coverage; tons measure the asphalt material.
- Compacted asphalt weighs about 145 pounds per cubic foot.
- Standard residential thickness is 2 to 3 inches.
- Always add a little for waste; a contractor confirms the exact amount.
Frequently Asked Questions
How do I calculate how much asphalt I need?
Multiply the length by the width to get square feet, multiply by the thickness in feet to get cubic feet, then multiply by about 145 pounds per cubic foot and divide by 2,000 to get tons. The calculator above does it automatically.
How many square yards is my driveway?
Multiply length by width in feet, then divide by 9. A 40 by 12 foot driveway is 480 square feet, or about 53 square yards.
How thick should the asphalt be?
Two to three inches of compacted asphalt for a residential driveway, on a solid stone base. Heavier use or commercial lots need more.
How much does asphalt weigh?
Compacted hot-mix asphalt weighs roughly 145 pounds per cubic foot, or about 2 tons per cubic yard. That is the figure this calculator uses.
Is this calculator exact?
It is a solid planning estimate. Actual tonnage varies with the mix, compaction, and waste, so a contractor confirms the exact amount when quoting your job.
