- Angular crushed stone
Montana weather puts road and pad foundations through heat, heavy rain, and deep frost. East of the Continental Divide, gumbo clay can turn slick when wet and hard when dry, while valley gravel west of it behaves differently. #4 Crushed Stone is angular crushed aggregate with broad gaps that drain freely, helping limit water held around a heavy-use support course. This makes water management a recurring part of site preparation, especially where runoff concentrates along a slope or ditch.
That open structure suits ranch roads, shop pads, and erosion-control work where runoff needs handling. Its crushed form helps the aggregate resist shifting under heavy loads, though it is not intended as a tight finished driving surface. For a driveway exposed to Montana frost, place this stone in the open supporting course and use a finer compacting material above it.
