#2 Crushed Stone in Minnesota

Spring melt and deep frost put pressure on any Minnesota road base that holds water. #2 Crushed Stone remains an open layer made from large angular pieces, rather than closing into a finished surface. Fine material has been removed during washing, so the gaps between the stone remain available for drainage. That makes it useful around culverts, ditches, heavy pad bases, and access areas where standing water is a concern.

Lake cabin roads deserve drainage planning before stone is placed, since runoff needs a controlled route away from the drive and shoreline. Use #2 Crushed Stone below a finished road material where a heavy, draining layer is needed under traffic. It can also serve as a drainage layer below larger stone in a site feature that needs water to pass through the base. Its rough surface is not intended to provide the final driving finish, particularly where regular vehicle travel calls for a tighter top layer.

Construction Entrances

Place large angular rock at the point where trucks leave a work site for the road to help strip mud from their tires.

Culvert & Ditch Lining

Use substantial rock at culvert outlets and beside ditches where concentrated runoff could move lighter material.

Heavy Base Layers

Lay this as the bottom course for soft ground or frost-prone lanes and pads, then cover it with smaller stone.

Drainage Courses

The broad spaces between stones move high water volumes away from the project area.

Stays Put

Its weight and large pieces help it remain in place instead of rutting or being pushed aside by traffic.

Drains Fast

With washed stone and no fines, water has broad voids to travel through.

Bridges Soft Ground

Angular, oversized stone distributes weight over wet or weak subgrade.

Low Maintenance

After it is placed, upkeep is limited to adding more from time to time.
