How Much Does 40 Tons of Recycled Concrete Aggregate Cover?
How much does 40 tons of recycled concrete aggregate cover depends on how deep you spread it. At about 1.3 tons per cubic yard, 40 tons is roughly 30.8 cubic yards. Spread 4 inches deep, that covers about 2,492 square feet. Go thinner and it covers more; go deeper and it covers less.
Volume and tonnage calculator →How the coverage is figured
- Tons to cubic yards: 40 ÷ 1.3 = 30.8 yd³.
- Cubic yards to cubic feet: × 27 = 831 cu ft.
- Divide by depth in feet: at 4 inches (0.333 ft), 831 ÷ 0.333 = 2,492 sq ft.
Coverage of 40 tons at different depths
| Depth | Square feet covered | Square yards |
|---|---|---|
| 3 in | 3,323 | 369 |
| 4 in | 2,492 | 277 |
| 6 in | 1,662 | 185 |
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.
What 40 tons looks like on site
For delivery, 40 tons means multiple trips or a larger truck. Ask the supplier how they will split it. 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.
Where recycled concrete aggregate fits
Works well for:
- Driveway and pad bases
- Temporary construction entrances
- Fill under slabs when compacted in lifts
Think twice 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 3 inches takes about 6.0 tons.
- Weight used here: about 1.3 tons per cubic yard.
Mistakes that throw off the order
- Forgetting that compaction shrinks loose material. A loose 4-inch spread of a dense-graded stone may finish closer to 3 inches after rolling.
- Ignoring the base. A thin surface layer over soft soil fails early no matter how much material is on top.
- Measuring only the main rectangle. Aprons, turnouts and curved edges add real square footage.
- Assuming every supplier uses the same weight. Two yards selling the same product name can quote different tons per yard.
