How much recycled concrete aggregate for a 16x25 driveway: at 4 inches deep you need about 4.94 cubic yards, which is roughly 6.4 tons at 1.3 tons per yard. The driveway covers 400 square feet, so every inch of depth adds about 1.23 yards.
Volume and tonnage calculator →The math for a 16x25 driveway
- Area: 16 × 25 = 400 sq ft.
- Depth in feet: 4 ÷ 12 = 0.333 ft.
- Cubic feet: 400 × 0.333 = 133.3 cu ft.
- Cubic yards: ÷ 27 = 4.94 yd³.
- Tons: × 1.3 = 6.4 tons.
The volume and tonnage calculator does this for any size.
Recycled concrete aggregate needed by depth
| Depth | Cubic yards | Tons (approx.) | Tons +10% |
|---|---|---|---|
| 3 in | 3.70 | 4.8 | 5.3 |
| 4 in | 4.94 | 6.4 | 7.1 |
| 6 in | 7.41 | 9.6 | 10.6 |
About recycled concrete aggregate
Ask whether the recycled concrete has been screened for rebar and debris. Fresh-crushed concrete can also be alkaline, so keep it away from sensitive plantings and streams. 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. This driveway sees car and truck traffic, so match the depth to that load rather than to the minimum.
Ordering tips
- Round up. Compaction and uneven ground eat material. Adding about 10 percent is common.
- Delivery size. 7.1 tons fits in a single 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.
When to choose recycled concrete aggregate
Best suited to:
- Driveway and pad bases
- Temporary construction entrances
- Fill under slabs when compacted in lifts
Less suited to:
- 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 15x30 area at 3 inches takes about 5.4 tons.
- Weight used here: about 1.3 tons per cubic yard.
Common estimating mistakes
- Ordering exactly the math. Uneven ground and spillage nearly always need a little more than the flat calculation.
- Mixing up cubic yards and tons. Yards are volume, tons are weight; convert with the product’s weight per yard.
- Assuming every supplier uses the same weight. Two yards selling the same product name can quote different tons per yard.
- Measuring only the main rectangle. Aprons, turnouts and curved edges add real square footage.
