How Much Does 27 Tons of Asphalt Millings Cover?
How much does 27 tons of asphalt millings cover depends on how deep you spread it. At about 1.3 tons per cubic yard, 27 tons is roughly 20.8 cubic yards. Spread 4 inches deep, that covers about 1,682 square feet. Every added inch of depth cuts the coverage noticeably.
Volume and tonnage calculator →How the coverage is figured
- Tons to cubic yards: 27 ÷ 1.3 = 20.8 yd³.
- Cubic yards to cubic feet: × 27 = 561 cu ft.
- Divide by depth in feet: at 4 inches (0.333 ft), 561 ÷ 0.333 = 1,682 sq ft.
Coverage of 27 tons at different depths
| Depth | Square feet covered | Square yards |
|---|---|---|
| 3 in | 2,243 | 249 |
| 4 in | 1,682 | 187 |
| 6 in | 1,122 | 125 |
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 27 tons to use
For delivery, 27 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.

Where asphalt millings fits
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 20x25 area at 4 inches takes about 8.0 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.
- Using inches as if they were feet. Depth has to be divided by 12 before you multiply; skipping that step inflates the order twelvefold.
- Mixing up cubic yards and tons. Yards are volume, tons are weight; convert with the product’s weight per yard.
