How Much Does 4 Tons of Asphalt Millings Cover?
How much does 4 tons of asphalt millings cover depends on how deep you spread it. At about 1.3 tons per cubic yard, 4 tons is roughly 3.1 cubic yards. Spread 4 inches deep, that covers about 249 square feet. Every added inch of depth cuts the coverage noticeably.
Volume and tonnage calculator →How the coverage is figured
- Tons to cubic yards: 4 ÷ 1.3 = 3.1 yd³.
- Cubic yards to cubic feet: × 27 = 83 cu ft.
- Divide by depth in feet: at 4 inches (0.333 ft), 83 ÷ 0.333 = 249 sq ft.
Coverage of 4 tons at different depths
| Depth | Square feet covered | Square yards |
|---|---|---|
| 3 in | 332 | 37 |
| 4 in | 249 | 28 |
| 6 in | 166 | 18 |
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. 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.
Putting 4 tons to use
4 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.

Good and poor uses for 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
Poor fit 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.
Where estimates go wrong
- Ignoring the base. A thin surface layer over soft soil fails early no matter how much material is on top.
- 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.
- Using inches as if they were feet. Depth has to be divided by 12 before you multiply; skipping that step inflates the order twelvefold.
