Tons of Recycled Concrete Aggregate per Mile of 18 ft Road
Tons of recycled concrete aggregate per mile of 18 foot road: about 1,525 tons at 4 inches deep. The strip is 18 ft × 5,280 ft = 95,040 square feet. On a job this long, half an inch of extra depth adds a lot of tons.
Volume and tonnage calculator →Tons by depth
| Depth | Tons | Truckloads (~14 t) |
|---|---|---|
| 3 in | 1,144 | 82 |
| 4 in | 1,525 | 109 |
| 6 in | 2,288 | 164 |
| 8 in | 3,051 | 218 |
The math
- Area: 18 × 5,280 = 95,040 sq ft.
- Volume at 4 in: 95,040 × 0.333 = 31,680 cu ft (1,173 cubic yards).
- × 1.3 tons per yard = 1,525 tons.
Road section basics
At 18 feet wide, two cars can meet with care. 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. 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 recycled concrete aggregate
Works well for:
- Driveway and pad bases
- Temporary construction entrances
- Fill under slabs when compacted in lifts
Poor fit 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 20x25 area at 2 inches takes about 4.0 tons.
- Weight used here: about 1.3 tons per cubic yard.
Where estimates go wrong
- 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.
- Skipping drainage. Water sitting under any surface softens the base and leads to ruts and potholes.
- Mixing up cubic yards and tons. Yards are volume, tons are weight; convert with the product’s weight per yard.
