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 Concrete (RCA) 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 |
|---|---|---|---|
| Barn / Shed Foundation | 4 Inches | Crushed Concrete 21A | Provides exceptional bearing strength under concrete slabs. |
| Ranch / Field Driveway | 6 Inches | 2" Minus Recycled Concrete | Coarse aggregate interlocks to prevent mud rutting. |
💡 Contractor Installation Pro Tips
- Recycled crushed concrete (RCA) is typically 30% to 50% cheaper than virgin crushed limestone from quarries.
- Always specify "clean screened RCA" to ensure all rebar, wire, and demolition wood fines have been removed.
Frequently Asked Questions About Crushed Concrete (RCA) Calculator
Is crushed concrete as strong as regular gravel?
Yes! When compacted, crushed concrete re-hydrates slightly and interlocks into an extremely rigid, durable base course.
How much does a yard of crushed concrete weigh?
One cubic yard of crushed concrete weighs approximately 2,400 to 2,600 lbs (approx. 1.2 to 1.3 tons), making it slightly lighter than virgin granite.
