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 Driveway Gravel 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 |
|---|---|---|---|
| Surface Refresh (Top Coat) | 2 to 3 Inches | #57 Stone or Pea Gravel | Spread over an existing firm base to fill potholes and refresh curb appeal. |
| New Residential Driveway Base | 4 to 6 Inches | Crusher Run / #57 Stone | Requires mechanical rolling to interlock angular stones and prevent rutting under cars. |
| Heavy Vehicle / RV Driveway | 8 to 10 Inches | #3 Stone Base + #57 Surface | Two-layer installation over woven geotextile fabric to prevent sub-grade sinking. |
💡 Contractor Installation Pro Tips
- Always install non-woven landscape or driveway fabric beneath gravel to stop stones from sinking into muddy subsoil.
- Crown the center of your driveway 2-3 inches higher than the shoulders to ensure rainwater drains off rapidly.
- Order 10% to 15% extra material to account for compaction during rolling and settling into tire ruts.
Frequently Asked Questions About Driveway Gravel Calculator
How many tons of gravel do I need for a 50x12 driveway?
At a standard 4-inch depth with #57 stone (2,700 lbs/yd³), a 50 ft x 12 ft driveway requires approximately 7.41 cubic yards or 10.0 tons of gravel (plus a 5-10% buffer).
How many dump truck loads is 10 tons of driveway gravel?
A standard tandem axle dump truck carries around 10 to 14 tons per load, meaning a 10-ton driveway order can be delivered in a single full tandem dump truck trip.
What is the best type of gravel for a long driveway?
Crushed Stone #57 over a compacted Crusher Run (dense grade aggregate) base is considered the gold standard because angular facets interlock to create a firm, non-shifting driving surface.
