Aggregate Base Course (1.5″ To 3.5″)

Aggregate Base Course in a 1.5” to 3.5” Size Range

Aggregate Base Course in the 1.5" to 3.5" size range is a foundational construction material composed of crushed stone or gravel. This material is produced by mechanically crushing larger rocks into angular fragments, ensuring a mix of particle sizes within the specified range. The larger aggregate pieces provide excellent load-bearing capacity and stability, making this base course ideal for supporting heavy structures.




The 1.5" to 3.5" size range is particularly effective for projects requiring robust drainage and structural support. The larger stones create voids that facilitate water movement, reducing the risk of pooling and frost heave. Common applications include road and highway sub-bases, parking lots, industrial yards, and large-scale commercial or residential driveways. While this size offers superior strength and drainage, it is less suitable for areas requiring a smooth, compacted surface, as the larger stones can be difficult to grade and compact tightly. Overall, this aggregate base course is a reliable choice for demanding load-bearing and drainage applications.
