How Much Recycled Concrete Aggregate for a 18x25 Driveway?
A 18 by 25 foot driveway is 450 square feet. How much recycled concrete aggregate for a 18x25 driveway depends on depth: at 4 inches it is about 5.56 cubic yards or 7.2 tons. Suppliers usually sell by the ton, so the tonnage is the number to give them.
Volume and tonnage calculator →The math for a 18x25 driveway
- Area: 18 × 25 = 450 sq ft.
- Depth in feet: 4 ÷ 12 = 0.333 ft.
- Cubic feet: 450 × 0.333 = 150.0 cu ft.
- Cubic yards: ÷ 27 = 5.56 yd³.
- Tons: × 1.3 = 7.2 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 | 4.17 | 5.4 | 6.0 |
| 4 in | 5.56 | 7.2 | 7.9 |
| 6 in | 8.33 | 10.8 | 11.9 |
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. Weight per yard is a planning number; the scale ticket at the yard is the real one.
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. 7.9 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
Good uses:
- 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 8x16 area at 3 inches takes about 1.5 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.
- Ignoring the base. A thin surface layer over soft soil fails early no matter how much material is on top.
- 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.
