A 20 by 60 foot driveway is 1,200 square feet. How much recycled concrete aggregate for a 20x60 driveway depends on depth: at 4 inches it is about 14.81 cubic yards or 19.3 tons. Suppliers usually sell by the ton, so the tonnage is the number to give them.

The math for a 20x60 driveway

Area: 20 × 60 = 1,200 sq ft.
Depth in feet: 4 ÷ 12 = 0.333 ft.
Cubic feet: 1,200 × 0.333 = 400.0 cu ft.
Cubic yards: ÷ 27 = 14.81 yd³.
Tons: × 1.3 = 19.3 tons.

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 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. 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. 21.2 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.

When to choose 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 20x25 area at 2 inches takes about 4.0 tons.
Weight used here: about 1.3 tons per cubic yard.

Mistakes that throw off the order

Skipping drainage. Water sitting under any surface softens the base and leads to ruts and potholes.
Using inches as if they were feet. Depth has to be divided by 12 before you multiply; skipping that step inflates the order twelvefold.
Ignoring the base. A thin surface layer over soft soil fails early no matter how much material is on top.
Forgetting that compaction shrinks loose material. A loose 4-inch spread of a dense-graded stone may finish closer to 3 inches after rolling.
