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 Crushed Stone #57 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 |
|---|---|---|---|
| Concrete Slab Sub-base | 4 Inches | Crushed Stone #57 | Provides uniform capillary break and level load distribution under 4" concrete pours. |
| Retaining Wall Trench Backfill | 12 Inches | Clean Washed #57 | Prevents hydrostatic pressure build-up behind concrete and timber retaining walls. |
| Heavy Paver Base | 4 to 6 Inches | Crushed Stone #57 + Sand | Compacts firmly without washing away under heavy ground thaw/freeze cycles. |
💡 Contractor Installation Pro Tips
- #57 stone contains stones sized 1/2" to 1" with no fine dust, ensuring high drainage voids of 40% to 50%.
- If you need a solid pack that does not shift at all, consider Crusher Run (Dense Grade Aggregate) instead of clean #57.
