Gravel Layer & Excavation Cross-Section Simulator
Visualize multi-layer ground excavation, plate compaction settling, and dump truck hauling logistics in real-time.
To achieve a final compacted depth of 6.0 inches, you must spread 7.1 inches of loose uncompacted aggregate before running the plate compactor.
Recommended Depth & Base Specifications for Crusher Run (DGA) Calculator
Selecting the proper installation depth is the single most critical factor in preventing premature rutting, sinking, or weed breakthrough.
| Layer / Application | Recommended Depth | Stone Aggregate Type | Contractor Notes |
|---|---|---|---|
| Driveway Base Course | 4 to 6 Inches | Crusher Run (1" minus) | Fines and angular rocks lock into concrete-like density when compacted. |
| Heavy Equipment Roadway | 8 Inches | Crusher Run (2" minus) | Maximum load bearing capacity over soft clay soils. |
💡 Contractor Installation Pro Tips
- Crusher run contains stone dust fines: when rolled and watered, it cures into a near-solid cementitious layer.
- Always add 18% to your volume calculation to account for compaction shrinkage.
Frequently Asked Questions About Crusher Run (DGA) Calculator
What is crusher run?
Crusher run (also called Dense Grade Aggregate, ABC, or 21A) is a mix of angular crushed stone (from 3/4" down to fine stone dust) that compacts extremely tightly.
How heavy is a yard of crusher run?
One cubic yard of crusher run weighs approximately 3,000 lbs (1.50 tons).
