AGGREGATE BASE COURSE
We deliver itAggregate Base Course (1.5″ Minus, Non-Spec, Subbase)
Aggregate Base Course in a 1.5" minus size range is a blend of crushed stone, gravel, and fines, designed for use as a foundational layer beneath roads, driveways, and concrete slabs. The "non-spec" attribute means this material is not produced to meet strict state or DOT specifications, making it a cost-effective choice for projects where certified gradation is not required. As a subbase, it provides essential support and load distribution for overlying surfaces.
