How Much Does 24 Tons of Road Base Cover?
How much does 24 tons of road base cover depends on how deep you spread it. At about 1.5 tons per cubic yard, 24 tons is roughly 16.0 cubic yards. Spread 6 inches deep, that covers about 864 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: 24 ÷ 1.5 = 16.0 yd³.
- Cubic yards to cubic feet: × 27 = 432 cu ft.
- Divide by depth in feet: at 6 inches (0.500 ft), 432 ÷ 0.500 = 864 sq ft.
Coverage of 24 tons at different depths
| Depth | Square feet covered | Square yards |
|---|---|---|
| 4 in | 1,296 | 144 |
| 6 in | 864 | 96 |
| 8 in | 648 | 72 |
About road base
Road base is meant to be compacted at close to the right moisture. Dry base rock does not lock up well; a light spray of water before rolling helps. Weight runs about 1.4 to 1.65 compacted tons per cubic yard, so treat the table as a planning range rather than an exact figure.
Putting 24 tons to use
24 tons will usually take two or more truck loads, 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.
Good and poor uses for road base
Good uses:
- Base under asphalt and concrete
- Gravel roads and drives
- Equipment and shed pads
Less suited to:
- Drainage layers
- Decorative surfaces
- Surfaces that will stay uncompacted
Quick reference numbers
- Per inch over 100 sq ft: about 0.46 tons of road base (0.31 cubic yards).
- Per inch over 1,000 sq ft: about 4.6 tons.
- Another size for comparison: a 8x16 area at 3 inches takes about 1.8 tons.
- Weight used here: about 1.5 tons per cubic yard.
Where estimates go wrong
- Assuming every supplier uses the same weight. Two yards selling the same product name can quote different tons per yard.
- Ignoring the base. A thin surface layer over soft soil fails early no matter how much material is on top.
- Using inches as if they were feet. Depth has to be divided by 12 before you multiply; skipping that step inflates the order twelvefold.
- Ordering exactly the math. Uneven ground and spillage nearly always need a little more than the flat calculation.
