Asphalt Tonnage Calculator
An asphalt tonnage calculator finds the tons of hot mix asphalt you need by converting your paving volume to weight. Multiply area by thickness for cubic feet, by 145 pounds per cubic foot, then divide by 2,000 for tons. Enter your dimensions below to get the tonnage to order.

How Do You Calculate Asphalt Tonnage?
To calculate asphalt tonnage, find the volume in cubic feet (area times thickness in feet), multiply by 145 pounds per cubic foot, and divide by 2,000 to convert pounds to tons. A 100 by 10 foot path at 2 inches thick is about 166.7 cubic feet, roughly 12.1 tons. Because asphalt is ordered by the ton, this is the number your supplier needs, and the calculator gives it directly.
Why Is Asphalt Ordered by Tonnage?
Asphalt is ordered by tonnage because hot mix is produced and priced by weight at the plant, and trucks are loaded by the ton. Volume is only an intermediate step, so the tonnage figure is what you place on the order and what contractors quote against. A small overage allowance is wise, since asphalt compacts during paving and edges need extra.

Frequently asked questions
- How do I calculate tons of asphalt?
- Multiply area by thickness in feet for cubic feet, multiply by 145 pounds, and divide by 2,000 for tons. The calculator does this and adds a compaction allowance.
- How many square feet does a ton of asphalt cover?
- At 2 inches thick, a ton of hot mix asphalt covers about 80 square feet. The coverage falls as the thickness rises.
