The math for a 14x75 driveway

Area: 14 × 75 = 1,050 sq ft.
Depth in feet: 4 ÷ 12 = 0.333 ft.
Cubic feet: 1,050 × 0.333 = 350.0 cu ft.
Cubic yards: ÷ 27 = 12.96 yd³.
Tons: × 1.3 = 16.9 tons.

About asphalt millings

Millings vary by source: some loads are fine and uniform, others carry chunks. Ask the supplier for a screened product if you want a smoother finish, and check local rules, since some areas restrict their use near water. 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. For car and truck traffic, the depths in the table above are a reasonable starting range.

Ordering tips

Round up. Compaction and uneven ground eat material. Adding about 10 percent is common.
Delivery size. 18.5 tons may take more than one 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

Best suited to:

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 15x30 area at 4 inches takes about 7.2 tons.
Weight used here: about 1.3 tons per cubic yard.

Mistakes that throw off the order

Measuring only the main rectangle. Aprons, turnouts and curved edges add real square footage.
Ignoring the base. A thin surface layer over soft soil fails early no matter how much material is on top.
Ordering exactly the math. Uneven ground and spillage nearly always need a little more than the flat calculation.
Forgetting that compaction shrinks loose material. A loose 4-inch spread of a dense-graded stone may finish closer to 3 inches after rolling.
