Tons of Road Base per 100 Feet of 10 ft Road
Tons of road base per 100 feet of 10 foot road: about 28 tons at 6 inches deep. The strip is 10 ft × 100 ft = 1,000 square feet. Shoulders, pullouts and turnarounds add to the total; measure them separately.
Volume and tonnage calculator →Tons by depth
| Depth | Tons | Truckloads (~14 t) |
|---|---|---|
| 3 in | 14 | 1 |
| 4 in | 19 | 2 |
| 6 in | 28 | 2 |
| 8 in | 37 | 3 |
The math
- Area: 10 × 100 = 1,000 sq ft.
- Volume at 6 in: 1,000 × 0.500 = 500 cu ft (19 cubic yards).
- × 1.5 tons per yard = 28 tons.
Road section basics
A 10-foot width fits one lane of traffic. 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. Crown the surface so water sheds to ditches on both sides.
Practical notes
- Phasing. Large tonnages are delivered over days; schedule spreading and compaction to keep up with trucks.
- Waste. Allow 5 to 10 percent.
- Hauling. Distance from the quarry or plant often costs as much as the material on long jobs; see asphalt hauling cost per ton.

When to choose road base
Works well for:
- Base under asphalt and concrete
- Gravel roads and drives
- Equipment and shed pads
Poor fit 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 14x28 area at 2 inches takes about 3.6 tons.
- Weight used here: about 1.5 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.
- Skipping drainage. Water sitting under any surface softens the base and leads to ruts and potholes.
