Asphalt Calculator

Estimate asphalt volume, weight, and tons from area and thickness. Editable density with industry-default range.

Formula

Weight = volume × density. Tons = weight ÷ 2000 lb. Default density 145 lb/ft³ (typical range 140–150).

Assumptions

  • Default density of 145 lb/ft³ represents a typical hot-mix asphalt range of 140–150 lb/ft³.
  • Waste percentage accounts for compaction and edge trimming.

Limitations

  • Actual tonnage varies with mix design, compaction, and temperature.
  • Does not model sub-base or drainage layers.

Worked example

1,000 sq ft at 2 in thick

Volume ≈ 166.67 cu ft. At 145 lb/ft³, weight ≈ 24,167 lb ≈ 12.08 tons.

Frequently asked questions

What density should I use?

Hot-mix asphalt typically ranges from 140 to 150 pounds per cubic foot depending on the mix design. The default is 145 lb/ft³ — adjust for your specific mix.
