Crushed Concrete Calculator
Calculate how much crushed concrete (recycled aggregate) you need for driveways and bases, in cubic yards and tons.
Crushed Concrete Calculator (Recycled Aggregate) Guide
The crushed concrete calculator estimates how much recycled concrete aggregate you need—in cubic yards and tons—for driveways, sub-bases, and fill. Crushed concrete is a cheaper, eco-friendly alternative to virgin crushed stone that compacts into a hard, stable base.
How to Calculate Crushed Concrete
Multiply length × width × depth (in feet), divide by 27 for cubic yards, then multiply by about 1.35 to get tons, since a cubic yard of crushed concrete weighs roughly 2,400–2,700 lb. For a driveway, lay 4–6 inches and compact it in lifts. Because it contains fines, crushed concrete binds tightly—much like our crushed stone and 2A modified stone bases.
Frequently Asked Questions
How much crushed concrete do I need?
Measure length, width, and depth in feet, multiply them, and divide by 27 for cubic yards. For a 4-inch driveway base over 500 square feet, you need about 6.2 cubic yards (roughly 8.3 tons). Add 10% for compaction.
Is crushed concrete as good as crushed stone?
For driveways and sub-bases, crushed concrete performs comparably to crushed stone and costs less, while reusing material that would otherwise be landfilled. It compacts firmly thanks to its fines. For finished decorative surfaces, natural stone is usually preferred.
How much does a yard of crushed concrete weigh?
A cubic yard of crushed concrete weighs roughly 2,400–2,700 pounds (about 1.2–1.35 tons). Weight varies with moisture and the proportion of fines in the mix.
How deep should crushed concrete be for a driveway?
Lay 4–6 inches of crushed concrete for a residential driveway, compacted in 2-inch lifts. Over soft or clay soils, increase the depth and add a geotextile fabric beneath to stop the base sinking into the subgrade.
