#2 Crushed Stone in North Dakota

Spring thaw can leave North Dakota clay holding water in the Red River Valley, while gumbo west of the Missouri can become difficult under traffic. #2 Crushed Stone leaves an open bed of large angular pieces rather than closing into a dense cap. Washing takes out the fine material, so the spaces between pieces remain available for drainage.

Construction entrances benefit from this stone where vehicles arrive carrying mud. The weight and angular shape help it stay put under tires on the rough approach. On shelterbelt lanes or pad foundations, account for deep frost before building the support layers. Cover this coarse layer with a material intended to make the travel surface where regular driving is expected.

Construction Entrances

At a site access, a substantial layer of large angular stone helps clear mud from truck tires before vehicles reach the road.

Culvert & Ditch Lining

Use heavy rock at culvert outlets and along ditches that carry concentrated runoff to help keep the material from moving.

Heavy Base Layers

Lay it first over soft ground for farm lanes or equipment pads, then add smaller stone above it.

Drainage Courses

The open spaces among the rock allow a high volume of water to flow away from the work area.

Remains in Place

The large, weighty pieces are less likely to rut or get pushed out by tire traffic.

Open Drainage

With fines removed, washed stone leaves open voids that let water pass through.

Bridges Soft Ground

Large angular rock helps carry loads over saturated or unstable ground.

Low Maintenance

After installation, it generally only needs an occasional additional layer.
