How Much Road Base for a 10x24 Parking Pad?
How much road base for a 10x24 parking pad: at 4 inches deep you need about 2.96 cubic yards, which is roughly 4.4 tons at 1.5 tons per yard. The parking pad covers 240 square feet, so every inch of depth adds about 0.74 yards.
Volume and tonnage calculator →The math for a 10x24 parking pad
- Area: 10 × 24 = 240 sq ft.
- Depth in feet: 4 ÷ 12 = 0.333 ft.
- Cubic feet: 240 × 0.333 = 80.0 cu ft.
- Cubic yards: ÷ 27 = 2.96 yd³.
- Tons: × 1.5 = 4.4 tons.
The volume and tonnage calculator does this for any size.
Road base needed by depth
| Depth | Cubic yards | Tons (approx.) | Tons +10% |
|---|---|---|---|
| 4 in | 2.96 | 4.4 | 4.9 |
| 6 in | 4.44 | 6.7 | 7.3 |
| 8 in | 5.93 | 8.9 | 9.8 |
About road base
Road base is meant to be compacted at close to the right moisture. Dry base rock does not lock up well; a light spray of water before rolling helps. If the yard sells by the cubic yard instead of the ton, use the cubic-yard column directly.
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. 4.9 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 parking pad as firm ground allows.
When to choose road base
Best suited to:
- Base under asphalt and concrete
- Gravel roads and drives
- Equipment and shed pads
Think twice for:
- Drainage layers
- Decorative surfaces
- Surfaces that will stay uncompacted
Quick reference numbers
- Per inch over 100 sq ft: about 0.46 tons of road base (0.31 cubic yards).
- Per inch over 1,000 sq ft: about 4.6 tons.
- Another size for comparison: a 8x16 area at 4 inches takes about 2.4 tons.
- Weight used here: about 1.5 tons per cubic yard.
Mistakes that throw off the order
- Ordering exactly the math. Uneven ground and spillage nearly always need a little more than the flat calculation.
- Ignoring the base. A thin surface layer over soft soil fails early no matter how much material is on top.
- Using inches as if they were feet. Depth has to be divided by 12 before you multiply; skipping that step inflates the order twelvefold.
- Assuming every supplier uses the same weight. Two yards selling the same product name can quote different tons per yard.
