Question 1

How much asphalt do I need?

Accepted Answer

Measure the paved area, choose the compacted thickness, multiply area by thickness to get volume, then convert volume to tons using asphalt density. For compacted hot mix asphalt, 145 pounds per cubic foot is a common planning value. Add 5% to 10% extra for waste and edge work.

Question 2

Is this an asphalt calculator, asphalt estimator, or asphalt volume calculator?

Accepted Answer

It works as all three. Use it as an asphalt calculator for length, width, and thickness; as an asphalt estimator for tons and cost; and as an asphalt volume calculator for cubic feet, cubic yards, and cubic meters.

Question 3

How do I use the asphalt volume calculator?

Accepted Answer

Enter the paved area or length and width, then enter the asphalt thickness. The calculator converts those measurements into volume, weight, and recommended order quantities using the selected asphalt density.

Question 4

How is asphalt volume calculated?

Accepted Answer

Asphalt volume is calculated by multiplying length, width, and thickness. Convert inches to feet, divide cubic feet by 27 for cubic yards, then multiply by asphalt density to estimate weight.

Question 5

How much does asphalt weigh per cubic foot?

Accepted Answer

Standard compacted hot mix asphalt weighs about 145 pounds per cubic foot, or about 2,322 kilograms per cubic meter. Actual density varies by mix design and compaction.

Question 6

Should I add extra asphalt for waste?

Accepted Answer

Yes. Add 5% to 10% extra asphalt for waste, compaction, uneven surfaces, and measurement variation. This calculator includes a 5% order buffer.
