Aggregate Base Course (1.5″ Minus, Crusher Run)

Aggregate Base Course - Crusher Run, 1.5” Minus

Aggregate Base Course with a Crusher Run attribute in a 1.5" minus size range is a foundational construction material composed of crushed stone blended with fines. The "crusher run" designation means the material includes both larger angular stones and smaller particles, resulting from the mechanical crushing process. The 1.5" minus size indicates that the largest pieces are 1.5 inches in diameter or smaller, with a well-graded mix down to fine dust.




This specific combination offers excellent compaction and load-bearing properties, making it ideal for use as a stable sub-base beneath roads, driveways, parking lots, and concrete slabs. The fines fill voids between larger stones, creating a dense, interlocking structure that resists shifting and settling. While its high compaction makes it less suitable for drainage applications, it excels in providing a solid, long-lasting foundation for both residential and commercial projects. The main advantage of 1.5" minus crusher run is its ability to create a smooth, stable surface that supports heavy loads, though it may require mechanical compaction for best results.
