How Much Does 7 Tons of Asphalt Millings Cover?
How much does 7 tons of asphalt millings cover depends on how deep you spread it. At about 1.3 tons per cubic yard, 7 tons is roughly 5.4 cubic yards. Spread 4 inches deep, that covers about 436 square feet. Halve the depth and you roughly double the area.
Volume and tonnage calculator →How the coverage is figured
- Tons to cubic yards: 7 ÷ 1.3 = 5.4 yd³.
- Cubic yards to cubic feet: × 27 = 145 cu ft.
- Divide by depth in feet: at 4 inches (0.333 ft), 145 ÷ 0.333 = 436 sq ft.
Coverage of 7 tons at different depths
| Depth | Square feet covered | Square yards |
|---|---|---|
| 3 in | 582 | 65 |
| 4 in | 436 | 48 |
| 6 in | 291 | 32 |
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. Weight runs about 1.2 to 1.4 loose tons per cubic yard, so treat the table as a planning range rather than an exact figure.
What 7 tons looks like on site
7 tons is a light load that a single-axle dump truck can often handle, though legal limits vary by truck and state. Spread from the pile with a loader, skid steer or wheelbarrow, then rake to depth before compacting if the material calls for it.
- Check depth as you go. Stakes marked at the target depth help keep the spread even.
- Expect some loss. Compaction and uneven ground use more than the flat-math figure. Keep about 10 percent in reserve.
- Ask about moisture. Wet material weighs more, so a ton of it covers less.
To run your own numbers, use the volume and tonnage calculator.
When to choose asphalt millings
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
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 15x30 area at 4 inches takes about 7.2 tons.
- Weight used here: about 1.3 tons per cubic yard.
Where estimates go wrong
- Using inches as if they were feet. Depth has to be divided by 12 before you multiply; skipping that step inflates the order twelvefold.
- Ignoring the base. A thin surface layer over soft soil fails early no matter how much material is on top.
- Forgetting that compaction shrinks loose material. A loose 4-inch spread of a dense-graded stone may finish closer to 3 inches after rolling.
- Mixing up cubic yards and tons. Yards are volume, tons are weight; convert with the product’s weight per yard.
