15 Cubic Yards of Road Base in Tons
15 cubic yards of road base in tons works out to about 22.5 tons using a planning weight of 1.5 tons per yard. Real loads land between roughly 21.0 and 24.8 tons depending on stone size, fines and moisture. That is about 45,000 pounds.
Volume and tonnage calculator →The conversion
- Yards × tons per yard: 15 × 1.5 = 22.5 tons.
- Low end: 15 × 1.4 = 21.0 tons.
- High end: 15 × 1.65 = 24.8 tons.
If your supplier quotes a different weight per yard, multiply by theirs.

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.
Hauling 15 yards
At about 22.5 tons, this is more than one typical truckload. A pickup is a poor fit for anything past a fraction of a yard; see how much gravel a half-ton pickup can carry.
Before you order
- Confirm whether the yard prices road base by the ton or by the yard.
- Add about 10 percent for compaction and uneven ground.
- Clear a firm spot for the truck to dump.
The volume and tonnage calculator converts any area and depth into yards and tons.
Good and poor uses for road base
Best suited to:
- Base under asphalt and concrete
- Gravel roads and drives
- Equipment and shed pads
Think twice for:
- 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 20x25 area at 4 inches takes about 9.3 tons.
- Weight used here: about 1.5 tons per cubic yard.
Where estimates go wrong
- Forgetting that compaction shrinks loose material. A loose 4-inch spread of a dense-graded stone may finish closer to 3 inches after rolling.
- Skipping drainage. Water sitting under any surface softens the base and leads to ruts and potholes.
- Measuring only the main rectangle. Aprons, turnouts and curved edges add real square footage.
- Ordering exactly the math. Uneven ground and spillage nearly always need a little more than the flat calculation.
