About recycled concrete aggregate
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. Expect the weight to fall in the range of 1.2 to 1.4 tons per yard.
Getting the order right
- Measure odd shapes in pieces. Split curves and L-shapes into rectangles and add them.
- Add a margin. About 10 percent covers compaction and low spots.
- Bulk or bags. Bulk delivery is the practical choice here.
- Prep first. Remove sod, compact the subgrade and set edging before the stone arrives.
Use the volume and tonnage calculator for any other size.
When to choose recycled concrete aggregate
Best suited to:
- 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 14x28 area at 4 inches takes about 6.3 tons.
- Weight used here: about 1.3 tons per cubic yard.
Common estimating mistakes
- Assuming every supplier uses the same weight. Two yards selling the same product name can quote different tons per yard.
- Ordering exactly the math. Uneven ground and spillage nearly always need a little more than the flat calculation.
- Mixing up cubic yards and tons. Yards are volume, tons are weight; convert with the product’s weight per yard.
- Using inches as if they were feet. Depth has to be divided by 12 before you multiply; skipping that step inflates the order twelvefold.
