How much crushed concrete do I need?

Crushed concrete (recycled concrete aggregate) is sold by the ton or cubic yard. Work out the volume, then convert:

Cubic yards = length (ft) × width (ft) × depth (ft) ÷ 27. Multiply cubic yards by the density to get tons. Crushed concrete weighs roughly 1.4 tons per cubic yard, a little more once fines are included.

As a rule of thumb, one ton of crushed concrete covers about 100 square feet at 2 inches deep, or roughly 65 sq ft at 3 inches.

Crushed concrete FAQs

How much crushed concrete do I need for a driveway?

Multiply length × width × depth (all in feet) to get cubic feet, divide by 27 for cubic yards, then multiply by about 1.4 for tons. For example, a 40 × 10 ft driveway at 4 inches deep needs about 5.9 cubic yards, or roughly 8.3 tons of crushed concrete (with a 20% compaction allowance).

How many tons are in a cubic yard of crushed concrete?

About 1.4 US tons per cubic yard for ¾″ crushed concrete. Road-base grade with fines packs tighter at around 1.5 tons per cubic yard.

Is crushed concrete good for a driveway?

Yes. Crushed concrete compacts into a hard, stable surface and is usually cheaper than virgin crushed stone, which makes it a popular choice for driveways, sub-bases, and fill. The graded version with fines locks together best.

How much area does a ton of crushed concrete cover?

About 100 square feet at 2 inches deep, or roughly 65 square feet at 3 inches. One cubic yard (≈1.4 tons) covers about 160 sq ft at 2 inches.

Is crushed concrete cheaper than gravel?

Usually, yes. Because it is recycled, crushed concrete often costs less per ton than quarried gravel or crushed stone while performing similarly as a compacted base, so it’s a budget-friendly option for large areas.
