How Much Does 20 Tons of Recycled Concrete Aggregate Cover?
How much does 20 tons of recycled concrete aggregate cover depends on how deep you spread it. At about 1.3 tons per cubic yard, 20 tons is roughly 15.4 cubic yards. Spread 4 inches deep, that covers about 1,246 square feet. Halve the depth and you roughly double the area.
Volume and tonnage calculator →How the coverage is figured
- Tons to cubic yards: 20 ÷ 1.3 = 15.4 yd³.
- Cubic yards to cubic feet: × 27 = 415 cu ft.
- Divide by depth in feet: at 4 inches (0.333 ft), 415 ÷ 0.333 = 1,246 sq ft.
Coverage of 20 tons at different depths
| Depth | Square feet covered | Square yards |
|---|---|---|
| 3 in | 1,662 | 185 |
| 4 in | 1,246 | 138 |
| 6 in | 831 | 92 |
About recycled concrete aggregate
Ask whether the recycled concrete has been screened for rebar and debris. Fresh-crushed concrete can also be alkaline, so keep it away from sensitive plantings and streams. Weight runs about 1.2 to 1.4 tons per cubic yard, so treat the table as a planning range rather than an exact figure.
Planning around 20 tons
20 tons will usually take two or more truck loads, though legal limits vary by truck and state. Spread from the pile with a loader, skid steer or wheelbarrow, then rake to depth before compacting if the material calls for it.
- Check depth as you go. Stakes marked at the target depth help keep the spread even.
- Expect some loss. Compaction and uneven ground use more than the flat-math figure. Keep about 10 percent in reserve.
- Ask about moisture. Wet material weighs more, so a ton of it covers less.
To run your own numbers, use the volume and tonnage calculator.
Good and poor uses for recycled concrete aggregate
Good uses:
- Driveway and pad bases
- Temporary construction entrances
- Fill under slabs when compacted in lifts
Less suited to:
- 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 10x20 area at 3 inches takes about 2.4 tons.
- Weight used here: about 1.3 tons per cubic yard.
Where estimates go wrong
- Mixing up cubic yards and tons. Yards are volume, tons are weight; convert with the product’s weight per yard.
- Measuring only the main rectangle. Aprons, turnouts and curved edges add real square footage.
- 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.
