The math for a 14x60 driveway

Area: 14 × 60 = 840 sq ft.
Depth in feet: 4 ÷ 12 = 0.333 ft.
Cubic feet: 840 × 0.333 = 280.0 cu ft.
Cubic yards: ÷ 27 = 10.37 yd³.
Tons: × 1.3 = 13.5 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. Ask your supplier for their own tons-per-yard figure, since stone source and moisture shift it.

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. 14.8 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.

When to choose asphalt millings

Good uses:

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

Less suited to:

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 12x24 area at 3 inches takes about 3.5 tons.
Weight used here: about 1.3 tons per cubic yard.

Common estimating mistakes

Mixing up cubic yards and tons. Yards are volume, tons are weight; convert with the product’s weight per yard.
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.
Skipping drainage. Water sitting under any surface softens the base and leads to ruts and potholes.
