How Much Recycled Concrete Aggregate for a 22x75 Driveway?

A 22 by 75 foot driveway is 1,650 square feet. How much recycled concrete aggregate for a 22x75 driveway depends on depth: at 4 inches it is about 20.37 cubic yards or 26.5 tons. Suppliers usually sell by the ton, so the tonnage is the number to give them.

The math for a 22x75 driveway

Area: 22 × 75 = 1,650 sq ft.
Depth in feet: 4 ÷ 12 = 0.333 ft.
Cubic feet: 1,650 × 0.333 = 550.0 cu ft.
Cubic yards: ÷ 27 = 20.37 yd³.
Tons: × 1.3 = 26.5 tons.

The volume and tonnage calculator does this for any size.

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. If the yard sells by the cubic yard instead of the ton, use the cubic-yard column directly.

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. Since the driveway carries car and truck traffic, a little extra depth is cheap insurance.

Ordering tips

Round up. Compaction and uneven ground eat material. Adding about 10 percent is common.
Delivery size. 29.1 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.

Where recycled concrete aggregate fits

Works well for:

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 20x25 area at 3 inches takes about 6.0 tons.
Weight used here: about 1.3 tons per cubic yard.

Where estimates go wrong

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.
Assuming every supplier uses the same weight. Two yards selling the same product name can quote different tons 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.
