How to install #4 Crushed Stone
-
1
Excavate
Strip topsoil to 6-10", with the depth set by traffic and the frost line in your area.
-
2
Lay geotextile fabric
Optional but worth it; a woven separator stops the base from migrating into native soil.
-
3
Spread base layer
Spread the stone in 2-3 inch lifts and compact each lift with a plate compactor before adding the next.
-
4
Crown the surface
Crown the top ~1/4" per foot toward the edges so water sheds.

Fixed our muddy farm lane
The lane to our barn turned into soup every spring. We had 20 tons of #4 spread as the bottom layer and it stopped the trucks sinking right away. Big chunky stone, locks together under weight, then we topped it with smaller gravel. Driver did a great job tailgating it down the lane so we barely had to push it around.

Heavy duty base stone
Used 10 tons of this as sub-base for a new driveway extension where the ground was soft. It is big crushed stone, roughly two inches, and it does exactly what a base should do. Be ready though, it is not something you spread with a garden rake, you want a machine or a strong back. A few pieces were larger than I expected but nothing unusable.

Stopped the erosion
We had erosion on a slope behind the house every time it stormed. Put 4 tons of #4 stone down and it has not moved since. Chunky gray rock, clean, hardly any fines to speak of. Truck handled our steep driveway fine.
