How this crushed concrete calculator works
Recycled concrete estimates exactly like virgin stone — volume times density — just a little lighter and a lot cheaper:
tons = yd³ × 1.35 × (1 + allowance%) → rounded up to ¼ ton
Worked example: crushed concrete for a 40 × 10 drive
400 ft² at 4 in is 133 ft³ — 4.94 yd³, or 6.7 tons of 21AA. With the 10% compaction allowance the order is 7.5 tons, about $225 at $30 a ton — the same lift in virgin limestone would run half again more.
How much does a ton of crushed concrete cover?

| 4″ | 60 ft² |
| 6″ | 40 ft² |
| Material | $/ton |
|---|---|
| Crushed concrete | $15–35 |
| Crushed limestone | $30–55 |
| Virgin crushed stone | $35–60 |
Crushed concrete FAQ
How much crushed concrete do I need?
Volume × 1.35 tons per cubic yard: the default 40 × 10 ft driveway lift at 4 in is 4.94 yd³ — 6.7 tons, ordered as 7.5 with 10% compaction allowance, about $225 at $30 a ton.
Is crushed concrete good for driveways?
Yes — it is one of the best budget driveway materials. The residual cement fines re-bind as the material weathers, so a compacted crushed-concrete drive tightens into an almost paved surface that sheds rutting better than loose gravel.
How many tons of crushed concrete are in a cubic yard?
About 1.35 tons for graded 21AA with fines, a touch less for clean #57 recycled at 1.3 — recycled concrete runs slightly lighter than virgin limestone because the old mortar is porous.
How much cheaper is crushed concrete than gravel?
Commonly 30–50% less: $15–35 per ton in 2026 against $35–60 for virgin crushed stone, because the feedstock is demolition waste diverted from landfill. Supply is local — near a crushing yard it is the obvious base choice.
How much does a ton of crushed concrete cover?
60 ft² at 4 in deep — 80 ft² at 3 in, 40 at 6 in. The live coverage figure under the drawing tracks whatever depth you set.
