#2 Crushed Stone in South Dakota

Trouble starts when #2 Crushed Stone is expected to tighten into a smooth travel surface. The angular stone stays coarse after placement, and washing leaves the spaces between pieces clear of fine material. That open condition suits construction entrances, culvert areas, and heavy support under farm building pads. On East River till or West River gumbo, it helps keep the base from becoming a closed, wet layer.

Build the working layer below an appropriate finished surface instead of relying on #2 Crushed Stone for the top of a road. This gives farm approaches and cabin roads a heavy stone foundation while the upper material handles regular travel. Deep frost and spring runoff can challenge ground across South Dakota, including sites near the Missouri River and in the Black Hills, so keep drainage considered as part of the layout.

Construction Entrances

Place a deep layer of angular rock at the point where site traffic reaches the road to strip mud from truck tires before it travels onto the roadway.

Runoff Protection

Place the larger rock around culvert outlets and beside ditches to help cover areas where runoff collects.

Heavy Base Layers

Install it as the bottom course over soft ground or below agricultural access routes and machinery pads, then cover it with smaller stone.

Drainage Courses

Its broad voids allow heavy water flow to pass through the layer instead of remaining at the site.

Traffic Stability

Its larger pieces and weight help limit tire-made ruts and reduce stone displacement.

Drains Fast

With no fines in washed stone, generous spaces remain between pieces for water to drain.

Bridges Soft Ground

Large angular rock distributes weight across saturated or unstable subgrade.

Low Maintenance

After it is installed, maintenance is usually limited to replenishing it from time to time.
