The math for a 12x60 driveway

Area: 12 × 60 = 720 sq ft.
Depth in feet: 4 ÷ 12 = 0.333 ft.
Cubic feet: 720 × 0.333 = 240.0 cu ft.
Cubic yards: ÷ 27 = 8.89 yd³.
Tons: × 1.3 = 11.6 tons.

About asphalt millings

Asphalt millings are ground-up old pavement. When compacted and warmed by sun they bind into a fairly firm surface, which is why they are popular for rural drives and lots. If the yard sells by the cubic yard instead of the ton, use the cubic-yard column directly.

Preparing the driveway

Strip sod and soft topsoil, grade for drainage and compact the subgrade before any stone goes down. Gravel drives last longer with a compacted base layer under the top stone and a slight crown so water runs off. This driveway sees car and truck traffic, so match the depth to that load rather than to the minimum.

Ordering tips

Round up. Compaction and uneven ground eat material. Adding about 10 percent is common.
Delivery size. 12.7 tons fits in a single typical dump truck load; small loads may carry a delivery fee. See how many tons of gravel in a dump truck.
Bulk vs bags. At this size bulk delivery is usually the practical choice.
Where it drops. Have the truck dump as close to the driveway as firm ground allows.

Where asphalt millings fits

Works well for:

Rural driveways and farm lanes
Parking areas where a dust-free surface is wanted
Low-cost base under a future paved surface

Think twice for:

Areas near wells or streams where local rules limit them
Decorative or barefoot areas
Jobs needing a uniform, clean look

Quick reference numbers

Per inch over 100 sq ft: about 0.40 tons of asphalt millings (0.31 cubic yards).
Per inch over 1,000 sq ft: about 4.0 tons.
Another size for comparison: a 14x28 area at 4 inches takes about 6.3 tons.
Weight used here: about 1.3 tons per cubic yard.

Mistakes that throw off the order

Forgetting that compaction shrinks loose material. A loose 4-inch spread of a dense-graded stone may finish closer to 3 inches after rolling.
Using inches as if they were feet. Depth has to be divided by 12 before you multiply; skipping that step inflates the order twelvefold.
Assuming every supplier uses the same weight. Two yards selling the same product name can quote different tons per yard.
Skipping drainage. Water sitting under any surface softens the base and leads to ruts and potholes.
