Tons of Crusher Run per 100 Feet of 28 ft Road
Tons of crusher run per 100 feet of 28 foot road: about 80 tons at 6 inches deep. The strip is 28 ft × 100 ft = 2,800 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 | 40 | 3 |
| 4 in | 54 | 4 |
| 6 in | 80 | 6 |
| 8 in | 107 | 8 |
The math
- Area: 28 × 100 = 2,800 sq ft.
- Volume at 6 in: 2,800 × 0.500 = 1,400 cu ft (52 cubic yards).
- × 1.55 tons per yard = 80 tons.
Road section basics
A 28-foot width gives two full lanes. Crusher run (also sold as crush and run, dense-grade aggregate or QP in some regions) mixes stone with stone dust. It compacts into a firm, nearly solid layer, which makes it the usual base under pavers, asphalt and gravel drives. 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.

Good and poor uses for crusher run
Works well for:
- Base under asphalt, pavers or concrete
- Gravel drives that need a firm, packed surface
- Shed pads and equipment pads
Less suited to:
- Drainage layers, since the fines slow water
- Decorative beds
- Spots where you want water to soak straight through
Quick reference numbers
- Per inch over 100 sq ft: about 0.48 tons of crusher run (0.31 cubic yards).
- Per inch over 1,000 sq ft: about 4.8 tons.
- Another size for comparison: a 15x30 area at 4 inches takes about 8.6 tons.
- Weight used here: about 1.55 tons per cubic yard.
Where estimates go wrong
- Skipping drainage. Water sitting under any surface softens the base and leads to ruts and potholes.
- Assuming every supplier uses the same weight. Two yards selling the same product name can quote different tons per yard.
- Ignoring the base. A thin surface layer over soft soil fails early no matter how much material is on top.
- Mixing up cubic yards and tons. Yards are volume, tons are weight; convert with the product’s weight per yard.
