Crusher Run Calculator
Estimate crusher run material for driveways, sub-bases, and paths. Uses density of 2,700 lb/yd³ (same as crushed stone). Default depth is 4 inches for a proper base layer.
Frequently Asked Questions
What is crusher run?
Crusher run is a mix of crushed stone and stone dust (also called quarry process or QP). The dust acts as a binder, making it compact tightly. It is ideal for driveways, walkways, and sub-base layers.
How much crusher run for a driveway?
A 20 by 40 ft driveway at 4 inches deep needs approximately 9.9 tons of crusher run.
How deep should crusher run be?
Use 4 inches for paths and patios, 6 inches for driveways, and 8 to 12 inches for areas with heavy vehicle traffic.
What is the weight of crusher run per yard?
Crusher run weighs approximately 2,700 lb per cubic yard, which is about 1.35 tons per cubic yard.
Crusher run vs gravel — which is better for driveways?
Crusher run compacts significantly better than plain gravel because the stone dust acts as a natural binder. Pea gravel and river gravel stay loose and tend to shift under traffic, while crusher run locks in place after compaction.
