How Much Does 30 Tons of Asphalt Millings Cover?
How much does 30 tons of asphalt millings cover depends on how deep you spread it. At about 1.3 tons per cubic yard, 30 tons is roughly 23.1 cubic yards. Spread 4 inches deep, that covers about 1,869 square feet. Go thinner and it covers more; go deeper and it covers less.
Volume and tonnage calculator →How the coverage is figured
- Tons to cubic yards: 30 ÷ 1.3 = 23.1 yd³.
- Cubic yards to cubic feet: × 27 = 623 cu ft.
- Divide by depth in feet: at 4 inches (0.333 ft), 623 ÷ 0.333 = 1,869 sq ft.
Coverage of 30 tons at different depths
| Depth | Square feet covered | Square yards |
|---|---|---|
| 3 in | 2,492 | 277 |
| 4 in | 1,869 | 208 |
| 6 in | 1,246 | 138 |
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.
Planning around 30 tons
For delivery, 30 tons means multiple trips or a larger truck. Ask the supplier how they will split it. 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.

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
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 2 inches takes about 3.1 tons.
- Weight used here: about 1.3 tons per cubic yard.
Mistakes that throw off the order
- Assuming every supplier uses the same weight. Two yards selling the same product name can quote different tons per yard.
- Ordering exactly the math. Uneven ground and spillage nearly always need a little more than the flat calculation.
- Measuring only the main rectangle. Aprons, turnouts and curved edges add real square footage.
- Skipping drainage. Water sitting under any surface softens the base and leads to ruts and potholes.
