Crusher Dust Calculator
Determine the quantity of crusher dust needed for compacted base layers and foundation preparation.
Crusher Dust Calculator - Calculate Compacted Base Material Quantity
The crusher dust calculator helps you determine the exact amount of crusher dust (also known as crusher run or 0/10 material) needed for compacted base preparation. This material is essential for creating stable foundations for driveways, patios, pathways, and other construction projects.
Crusher dust is a blend of stone dust and larger particles that compact to near 100% density, making it ideal for base preparation. It fills voids, compacts uniformly, and provides excellent load-bearing capabilities. For complete project planning, you may also need our stone compaction calculator to account for material settling and compression.
Crusher dust is typically applied in layers of 4-6 inches, with each layer compacted using a plate compactor before adding the next. The material's grading (mix of sizes) ensures optimal compaction and drainage. Professional contractors often use crusher dust as their preferred base material because of its reliability, cost-effectiveness, and superior compaction characteristics compared to other materials.
Frequently Asked Questions
How much crusher dust do I need for a base?
Most projects require 4-6 inches of compacted crusher dust. Calculate volume: length (ft) × width (ft) × depth in feet ÷ 27 = cubic yards. For a 20×20 ft area at 4 inches: 20 × 20 × 0.333 ÷ 27 = 4.9 cubic yards. The calculator handles this conversion automatically.
Is crusher dust the same as stone dust?
Crusher dust is a blend (typically 0-10mm or 3/8 inch) including fines and small stones, while stone dust refers to the fine particles alone. Crusher dust compacts better due to its particle size distribution. Both are used in base preparation but crusher dust is often preferred for its superior compaction and drainage.
How should crusher dust be installed?
Place crusher dust in 2-3 inch lifts (layers) and compact each lift with a plate compactor until firm. Don't spread the entire depth at once—layered installation ensures uniform compaction and better load-bearing. The calculator includes compaction factors to ensure you order enough material for proper installation.
Will crusher dust washout in rain?
Properly compacted crusher dust bonds well and resists washout. However, on slopes or areas with heavy water runoff, surface erosion may occur over time. Use landscape fabric or edging to contain material. Recompact annually if needed to maintain a stable surface.
Can I drive on crusher dust immediately?
Not safely—crusher dust needs time to settle and be properly compacted. After installation, wait at least 24-48 hours before driving light vehicles, and ensure it's been properly compacted in layers. Heavy equipment may still disturb newly installed crusher dust, so allow additional time if possible.
