Recycled Concrete Aggregate Tons per 100 Feet, 20 ft Road
Tons of recycled concrete aggregate per 100 feet of 20 foot road: about 32 tons at 4 inches deep. The strip is 20 ft × 100 ft = 2,000 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 | 24 | 2 |
| 4 in | 32 | 3 |
| 6 in | 48 | 4 |
| 8 in | 64 | 5 |
The math
- Area: 20 × 100 = 2,000 sq ft.
- Volume at 4 in: 2,000 × 0.333 = 667 cu ft (25 cubic yards).
- × 1.3 tons per yard = 32 tons.
What goes into the section
At 20 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.

When to choose recycled concrete aggregate
Best suited to:
- 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 8x16 area at 4 inches takes about 2.1 tons.
- Weight used here: about 1.3 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.
- 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.
- Forgetting that compaction shrinks loose material. A loose 4-inch spread of a dense-graded stone may finish closer to 3 inches after rolling.
