How Much Recycled Concrete Aggregate for a 22x40 Driveway?
How much recycled concrete aggregate for a 22x40 driveway: at 4 inches deep you need about 10.86 cubic yards, which is roughly 14.1 tons at 1.3 tons per yard. The driveway covers 880 square feet, so every inch of depth adds about 2.72 yards.
Volume and tonnage calculator →The math for a 22x40 driveway
- Area: 22 × 40 = 880 sq ft.
- Depth in feet: 4 ÷ 12 = 0.333 ft.
- Cubic feet: 880 × 0.333 = 293.3 cu ft.
- Cubic yards: ÷ 27 = 10.86 yd³.
- Tons: × 1.3 = 14.1 tons.

Recycled concrete aggregate needed by depth
| Depth | Cubic yards | Tons (approx.) | Tons +10% |
|---|---|---|---|
| 3 in | 8.15 | 10.6 | 11.7 |
| 4 in | 10.86 | 14.1 | 15.5 |
| 6 in | 16.30 | 21.2 | 23.3 |
About recycled concrete aggregate
Recycled concrete aggregate is crushed old concrete. It compacts well and often costs less than virgin stone, which makes it a common driveway and pad base. If the yard sells by the cubic yard instead of the ton, use the cubic-yard column directly.
Preparing the driveway
Strip sod and soft topsoil, grade for drainage and compact the subgrade before any stone goes down. Gravel drives last longer with a compacted base layer under the top stone and a slight crown so water runs off. Since the driveway carries car and truck traffic, a little extra depth is cheap insurance.
Ordering tips
- Round up. Compaction and uneven ground eat material. Adding about 10 percent is common.
- Delivery size. 15.5 tons may take more than one typical dump truck load; small loads may carry a delivery fee. See how many tons of gravel in a dump truck.
- Bulk vs bags. At this size bulk delivery is usually the practical choice.
- Where it drops. Have the truck dump as close to the driveway as firm ground allows.
Where recycled concrete aggregate fits
Best suited to:
- Driveway and pad bases
- Temporary construction entrances
- Fill under slabs when compacted in lifts
Poor fit for:
- Near ponds, streams or sensitive plants, since fresh crush can raise pH
- Decorative top layers
- Drainage layers, unless the product is clean and screened
Quick reference numbers
- Per inch over 100 sq ft: about 0.40 tons of recycled concrete aggregate (0.31 cubic yards).
- Per inch over 1,000 sq ft: about 4.0 tons.
- Another size for comparison: a 14x28 area at 4 inches takes about 6.3 tons.
- Weight used here: about 1.3 tons per cubic yard.
Where estimates go wrong
- Using inches as if they were feet. Depth has to be divided by 12 before you multiply; skipping that step inflates the order twelvefold.
- Forgetting that compaction shrinks loose material. A loose 4-inch spread of a dense-graded stone may finish closer to 3 inches after rolling.
- Ignoring the base. A thin surface layer over soft soil fails early no matter how much material is on top.
- Measuring only the main rectangle. Aprons, turnouts and curved edges add real square footage.
