Extra thickness or spillage. Starts at 0. The depth is already the compacted number you want.

Loose volume: 100 cu ft · 3.7 cu yd
Tons: 7.25 tons (145 lb/cu ft. Use the plant mix design if it differs.)

The order

A 12 by 50 foot drive at 2 inches is 100 cubic feet, 3.70 yards. At 145 pounds per cubic foot that is 7.25 tons. 145 is the number in the box for the example. If the ticket says something else, change the box. Do not borrow the gravel density.

Base under the mat is crushed stone. Figure that on the gravel calculator. Volume alone, without weight, is the cubic yard calculator.

Type the compacted thickness, not the loose pile. Do not reuse a gravel tonnage for hot mix. An apron and a patch are the same formula: add the areas, then one depth.

FAQ

How do I get tons?

Volume is area times depth. Weight is that volume times pounds per cubic foot, divided by 2,000. The form does not hide a density. Type the number from the plant.

Is this the same as gravel?

No. Gravel is loose aggregate with its own density. Asphalt is a paved mix, sold by the ton, and the depth you care about is the compacted thickness. Base rock under the asphalt is a gravel order.
