A 10×10 ft paver patio needs about 4.5 tons of crusher run for a 6 in compacted base (or 169 bags of 0.5 cu ft paver base), plus 18 bags of bedding sand and 40 ft of edge restraint.
| Base depth | Tons | 0.5 cu ft bags | Dig down |
|---|---|---|---|
| 4 in | 3 tons | 113 | 7.38 in |
| 6 in ✓ | 4.5 tons | 169 | 9.38 in |
| 8 in ✓ | 6 tons | 226 | 11.38 in |
| 10 in | 7.6 tons | 282 | 13.38 in |
| 12 in | 9.1 tons | 338 | 15.38 in |

Payload is on the Tire & Loading sticker in the driver's door jamb. Single-axle dump trucks carry about 5 tons; bigger orders come on a tandem (up to 18 tons).
Excavate 9.38 in below finished grade (6 in base + 1 in bedding + 2.375 in paver) over 121 sq ft. That is 3.5 cu yd of soil — about 5.2 tons in place, more once it is dug and loose. Slope the base away from the house (Unilock).

| Base depth | Crusher run | 0.5 cu ft bags | Bulk delivered | Dig down |
|---|---|---|---|---|
| 4 in | 3 tons | 113 | $163 | 7.38 in |
| 6 in | 4.5 tons | 169 | $207 | 9.38 in |
| 8 in | 6 tons | 226 | $250 | 11.38 in |
121 sq ft × 0.5 ft = 60.5 cu ft compacted = 2.24 cu yd. Crusher run compacts — Penn State places 8 in loose to finish at 6 in — so order 1.33× that, plus 5% for an uneven subgrade: 3.13 cu yd × 1.45 t = 4.54 tons.
County Materials' bag rule — (sq ft ÷ 6) × depth — gives 100 bags for the paved area alone. The 169 bags here add the base extension under the edge restraint and the volume lost to compaction; buying 100 would leave you about 69 bags short.
