#411 Stone: The Mix That Packs Hard on Driveways
#411 stone is a blend of #57 crushed stone and stone dust (screenings). The dust fills the gaps between the roughly 1-inch stones, so the mix packs into a firm, relatively smooth surface when compacted. It is popular for driveway surfaces, walkways, and as a base under pavers or sheds, particularly in parts of the Mid-Atlantic, including Pennsylvania and Maryland. Some suppliers also call it “411 limestone” or simply “411 driveway stone.”
Volume and tonnage calculator →What is in #411
- #57 stone: clean crushed stone, roughly 1 inch to 1/2 inch.
- Stone dust: fines and small chips, sometimes called #10 screenings.
- Result: an angular mix that locks together and binds as it gets wet and compacts.
Ratios vary by quarry. Some blends are coarser, others dustier.
#411 vs similar products
| Product | Makeup | Surface | Drainage |
|---|---|---|---|
| #411 | #57 stone plus stone dust | Firm, fairly smooth | Moderate |
| Crusher run | Dense-graded stone from about 1 to 2 inches down to dust | Firm, can be coarse | Moderate |
| #57 stone | Clean 1-inch to 1/2-inch stone | Loose, rough | Excellent |
| Stone dust | Fines | Smooth, can get muddy | Poor when compacted |
#411 is similar to crusher run, but because it is blended from two specific products, the size range is narrower and the surface often looks neater. See crusher run driveways.
Common uses
- Driveway topping over a coarser base.
- Walkways and paths that need a firm surface.
- Shed and playset pads.
- Base under pavers, compacted beneath bedding sand.
- Filling potholes in gravel driveways; it packs better than clean stone.
Weight and how much to order
#411 typically weighs around 1.4 to 1.5 tons per cubic yard compacted.
| Area | 3 inches | 4 inches |
|---|---|---|
| 10 x 50 feet (500 sq ft) | About 6.5 to 7 tons | About 8.6 to 9.3 tons |
| 12 x 100 feet (1,200 sq ft) | About 15.6 to 16.7 tons | About 20.8 to 22.2 tons |
Add about 10 percent for compaction and waste. The base calculator handles other sizes.
Installing #411
- Grade and compact the existing base or subgrade.
- Spread #411 evenly, typically 2 to 4 inches as a topping.
- Lightly wet the stone and compact it with a plate compactor or roller.
- Crown the driveway so water runs off the sides.
- Top up thin spots as needed over time.
Pros and cons
Pros: packs hard, fills ruts well, looks neat, and costs less than paving. Cons: can be dusty in dry weather, may get slightly muddy in very wet conditions, and needs occasional raking and topping.
Bottom line
#411 stone combines #57 stone with stone dust to create a firm, compactable surface for driveways, paths, and pads. Expect about 1.4 to 1.5 tons per compacted yard, compact it damp, and crown it for drainage.
