A cubic yard of crushed concrete weighs about 1.3 tons (2,600 lb) loose, as it comes off the truck — published factors run 1.21–1.4 tons.
“Cheapest” compares bulk delivered with 0.5 cu ft bags at the prices below.
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).
Bulk prices are typical 2026 yard and national-guide prices (American Rock Supply, Mulch Pros, Roseville Rock Supply); bag prices are retail snapshots. Tap any price to use your yard's.
| Depth | Sq ft per cu yd | Sq ft per ton | Tons per 100 sq ft |
|---|---|---|---|
| 1 in | 324 | 249 | 0.4 |
| 2 in | 162 | 125 | 0.8 |
| 3 in | 108 | 83 | 1.2 |
| 4 in | 81 | 62 | 1.6 |
| 6 in | 54 | 42 | 2.41 |
Weight converts yards to tons: tons = cubic yards × 1.3. A cubic yard is 27 cubic feet; spread 1 in deep it covers 324 sq ft, so coverage at any depth is 324 ÷ inches, and per ton it is 324 ÷ (inches × 1.3).
Quarry tables disagree because stone type, gradation and moisture change the weight, and because some list compacted rather than loose weights — Martin Marietta's "base" figures (1.90–1.95 t) are compacted-in-place values. If your yard prints a factor on its ticket or website, enter it in the calculator; it beats any average.
The budget driveway and pad base. Compacts like crusher run; may contain bits of rebar or brick.
