How Much Does 45 Tons of Crusher Run Cover?
How much does 45 tons of crusher run cover depends on how deep you spread it. At about 1.55 tons per cubic yard, 45 tons is roughly 29.0 cubic yards. Spread 6 inches deep, that covers about 1,568 square feet. Every added inch of depth cuts the coverage noticeably.
Volume and tonnage calculator →How the coverage is figured
- Tons to cubic yards: 45 ÷ 1.55 = 29.0 yd³.
- Cubic yards to cubic feet: × 27 = 784 cu ft.
- Divide by depth in feet: at 6 inches (0.500 ft), 784 ÷ 0.500 = 1,568 sq ft.
Coverage of 45 tons at different depths
| Depth | Square feet covered | Square yards |
|---|---|---|
| 3 in | 3,135 | 348 |
| 4 in | 2,352 | 261 |
| 6 in | 1,568 | 174 |
| 8 in | 1,176 | 131 |
About crusher run
The fines in crusher run fill the gaps between stones, so it weighs more per yard than clean stone once compacted. Plan on rolling or plate-compacting it in lifts. Weight runs about 1.5 to 1.7 compacted tons per cubic yard, so treat the table as a planning range rather than an exact figure.
Putting 45 tons to use
45 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.

Where crusher run fits
Works well for:
- Base under asphalt, pavers or concrete
- Gravel drives that need a firm, packed surface
- Shed pads and equipment pads
Think twice for:
- Drainage layers, since the fines slow water
- Decorative beds
- Spots where you want water to soak straight through
Quick reference numbers
- Per inch over 100 sq ft: about 0.48 tons of crusher run (0.31 cubic yards).
- Per inch over 1,000 sq ft: about 4.8 tons.
- Another size for comparison: a 15x30 area at 2 inches takes about 4.3 tons.
- Weight used here: about 1.55 tons per cubic yard.
Common estimating mistakes
- Mixing up cubic yards and tons. Yards are volume, tons are weight; convert with the product’s weight per yard.
- 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.
- Forgetting that compaction shrinks loose material. A loose 4-inch spread of a dense-graded stone may finish closer to 3 inches after rolling.
