Aggregate Base Course (1″ Minus, Crusher Run)

Aggregate Base Course - Crusher Run, 1” Minus

Aggregate Base Course with a Crusher Run attribute in a 1” minus size range is a foundational construction material composed of crushed stone and stone dust. The “crusher run” designation means the material includes a blend of various-sized particles, all the way down to fine dust, resulting from the mechanical crushing process. The 1” minus specification ensures that the largest particles are no bigger than one inch, with smaller pieces and fines filling the gaps.

This size and composition create a dense, well-graded material that compacts exceptionally well, making it ideal for use as a stable sub-base beneath roads, driveways, parking lots, patios, and walkways. The fines help bind the aggregate together, reducing voids and providing excellent load-bearing capacity. While its compactability is a major advantage, the presence of fines means it is less suitable for drainage applications compared to clean, washed stone. Overall, 1” minus crusher run aggregate base course is valued for its strength, stability, and versatility in both residential and commercial construction projects.
