How Much Road Base for a 24x200 Driveway?
How much road base for a 24x200 driveway: at 4 inches deep you need about 59.26 cubic yards, which is roughly 88.9 tons at 1.5 tons per yard. The driveway covers 4,800 square feet, so every inch of depth adds about 14.81 yards.
Volume and tonnage calculator →The math for a 24x200 driveway
- Area: 24 × 200 = 4,800 sq ft.
- Depth in feet: 4 ÷ 12 = 0.333 ft.
- Cubic feet: 4,800 × 0.333 = 1,600.0 cu ft.
- Cubic yards: ÷ 27 = 59.26 yd³.
- Tons: × 1.5 = 88.9 tons.

Road base needed by depth
| Depth | Cubic yards | Tons (approx.) | Tons +10% |
|---|---|---|---|
| 4 in | 59.26 | 88.9 | 97.8 |
| 6 in | 88.89 | 133.3 | 146.7 |
| 8 in | 118.52 | 177.8 | 195.6 |
About road base
Road base (also called base rock, ABC, or Class 2 base in different states) is a graded mix of stone and fines made to compact into a load-bearing layer. 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. For car and truck traffic, 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. 97.8 tons may take more than one 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 road base
Works well for:
- Base under asphalt and concrete
- Gravel roads and drives
- Equipment and shed pads
Less suited to:
- 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 12x24 area at 4 inches takes about 5.3 tons.
- Weight used here: about 1.5 tons per cubic yard.
Common estimating mistakes
- Mixing up cubic yards and tons. Yards are volume, tons are weight; convert with the product’s weight per yard.
- Ordering exactly the math. Uneven ground and spillage nearly always need a little more than the flat calculation.
- Skipping drainage. Water sitting under any surface softens the base and leads to ruts and potholes.
- Ignoring the base. A thin surface layer over soft soil fails early no matter how much material is on top.
