Recycled Concrete Aggregate for a 10x36 Parking Pad
How much recycled concrete aggregate for a 10x36 parking pad: at 4 inches deep you need about 4.44 cubic yards, which is roughly 5.8 tons at 1.3 tons per yard. The parking pad covers 360 square feet, so every inch of depth adds about 1.11 yards.
Volume and tonnage calculator →The math for a 10x36 parking pad
- Area: 10 × 36 = 360 sq ft.
- Depth in feet: 4 ÷ 12 = 0.333 ft.
- Cubic feet: 360 × 0.333 = 120.0 cu ft.
- Cubic yards: ÷ 27 = 4.44 yd³.
- Tons: × 1.3 = 5.8 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 | 3.33 | 4.3 | 4.8 |
| 4 in | 4.44 | 5.8 | 6.4 |
| 6 in | 6.67 | 8.7 | 9.5 |
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. Ask your supplier for their own tons-per-yard figure, since stone source and moisture shift it.
Preparing the parking pad
Dig out organic soil, compact the subgrade and set an edge so the stone does not migrate onto the lawn. A pad that holds parked weight for long periods benefits from a dense base under the surface stone. For parked vehicles, the depths in the table above are a reasonable starting range.
Ordering tips
- Round up. Compaction and uneven ground eat material. Adding about 10 percent is common.
- Delivery size. 6.4 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 parking pad as firm ground allows.
Where recycled concrete aggregate fits
Good uses:
- 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 8x16 area at 2 inches takes about 1.0 tons.
- Weight used here: about 1.3 tons per cubic yard.
Where estimates go wrong
- Ordering exactly the math. Uneven ground and spillage nearly always need a little more than the flat calculation.
- 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.
- Measuring only the main rectangle. Aprons, turnouts and curved edges add real square footage.
