#2 Crushed Stone in Missouri

After it settles into place, #2 Crushed Stone keeps open spaces between its angular pieces instead of tightening into a smooth driving surface. The stone is washed and free of fines, so those gaps remain available for water to move through. This behavior is useful where drainage is needed below construction entrances, culverts, or ditch work.

Ground conditions vary from the better-draining cherty soils of the Ozarks to northern glacial till and the wetter alluvium near the Mississippi River. For access roads or equipment areas on ground that holds moisture, use this stone as a heavy lower base layer. Add a finished driving gravel over it where the surface needs to carry regular traffic with a tighter finish.

Site Access Pads

At the road connection, large angular rock forms a thick pad that removes mud from truck tires before they leave the job site.

Culvert and Ditch Protection

Use heavy stone at culvert openings and beside drainage channels because it holds in areas where runoff gathers.

Support Layers

Place this as the initial layer below farm roads, machinery pads, or yielding soil, then add smaller aggregate over it.

Drainage Layers

The broad voids between pieces let substantial water flow pass through the rock and away from the area.

Holds Its Position

The weight and size of the rock help it remain in place under traffic and limit rutting.

Moves Water Quickly

With no fines in washed stone, open spaces remain for water to travel through.

Spans Weak Soil

Large angular rock distributes weight over damp or unstable subgrade.

Low Maintenance

It generally stays put, with periodic replenishment being the main upkeep.
