The math for a 22x300 driveway

Area: 22 × 300 = 6,600 sq ft.
Depth in feet: 4 ÷ 12 = 0.333 ft.
Cubic feet: 6,600 × 0.333 = 2,200.0 cu ft.
Cubic yards: ÷ 27 = 81.48 yd³.
Tons: × 1.3 = 105.9 tons.

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. Weight per yard is a planning number; the scale ticket at the yard is the real one.

Preparing the driveway

Strip sod and soft topsoil, grade for drainage and compact the subgrade before any stone goes down. Gravel drives last longer with a compacted base layer under the top stone and a slight crown so water runs off. This driveway sees car and truck traffic, so match the depth to that load rather than to the minimum.

Ordering tips

Round up. Compaction and uneven ground eat material. Adding about 10 percent is common.
Delivery size. 116.5 tons may take more than one typical dump truck load; small loads may carry a delivery fee. See how many tons of gravel in a dump truck.
Bulk vs bags. At this size bulk delivery is usually the practical choice.
Where it drops. Have the truck dump as close to the driveway as firm ground allows.

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 15x30 area at 2 inches takes about 3.6 tons.
Weight used here: about 1.3 tons per cubic yard.

Where estimates go wrong

Using inches as if they were feet. Depth has to be divided by 12 before you multiply; skipping that step inflates the order twelvefold.
Mixing up cubic yards and tons. Yards are volume, tons are weight; convert with the product’s weight per yard.
Skipping drainage. Water sitting under any surface softens the base and leads to ruts and potholes.
Forgetting that compaction shrinks loose material. A loose 4-inch spread of a dense-graded stone may finish closer to 3 inches after rolling.
