Recycled Concrete Aggregate for a 10x30 Parking Pad
A 10 by 30 foot parking pad is 300 square feet. How much recycled concrete aggregate for a 10x30 parking pad depends on depth: at 4 inches it is about 3.70 cubic yards or 4.8 tons. Suppliers usually sell by the ton, so the tonnage is the number to give them.
Volume and tonnage calculator →The math for a 10x30 parking pad
- Area: 10 × 30 = 300 sq ft.
- Depth in feet: 4 ÷ 12 = 0.333 ft.
- Cubic feet: 300 × 0.333 = 100.0 cu ft.
- Cubic yards: ÷ 27 = 3.70 yd³.
- Tons: × 1.3 = 4.8 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 | 2.78 | 3.6 | 4.0 |
| 4 in | 3.70 | 4.8 | 5.3 |
| 6 in | 5.56 | 7.2 | 7.9 |
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 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. 5.3 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
Best suited to:
- Driveway and pad bases
- Temporary construction entrances
- Fill under slabs when compacted in lifts
Think twice 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 15x30 area at 4 inches takes about 7.2 tons.
- Weight used here: about 1.3 tons per cubic yard.
Common estimating mistakes
- 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.
- Mixing up cubic yards and tons. Yards are volume, tons are weight; convert with the product’s weight per yard.
