#57 Crushed Stone Calculator
Calculate quantities for ASTM #57 crushed limestone, granite, and trap rock in cubic yards, tons, and bags.
1Project Shape & Dimensions
2Gravel Type & Density
The workhorse of aggregate. Angular, clean-washed 3/4-inch stones that lock together tightly. Perfect for driveway top coats, French drains, and concrete mixes.
3Gravel Depth & Compaction
Accounts for roller compaction settlement, uneven ground contours, and wheelbarrow spill.
Material & Delivery Cost Estimator
- Bulk delivery dump trucks usually require a 10–12 ft wide clearance path.
- Always verify if your quarry quotes in Tons or Cubic Yards.
- Order ~10% extra to prevent having to pay a second delivery fee for a half-ton deficit.
Why #57 Stone is the Top Choice for Driveway Surfaces
Unlike smooth gravel that rolls under car tires, #57 crushed stone features sharp fractured facets that mechanically interlock under vehicle weight while preserving 40% void space for rapid rainwater drainage.
Crushed Stone FAQs
Q: What size is #57 crushed stone?
#57 crushed stone refers to angular aggregate graded between 1/2 inch and 1 inch (averaging 3/4 inch). All stone dust and fines are screened out, leaving clean, open voids.
Q: How much does #57 crushed stone weigh per cubic yard?
Clean #57 crushed stone weighs approximately 1.45 US tons (2,900 lbs or 1,315 kg) per cubic yard.
Q: What is the difference between #57 stone and crusher run?
#57 stone is clean, washed stone with no fine particles, allowing water to drain freely through it. Crusher run (dense grade) contains both 3/4" stone and fine stone dust, which packs solid into an impermeable base under compaction.
