Aggregate Base Course (3/4″ To 1″)

Aggregate Base Course, 3/4” to 1” Minus

Aggregate Base Course in a 3/4" to 1" minus size range is a foundational construction material composed of crushed stone, gravel, and fines. The "minus" designation means the mix includes particles smaller than 3/4", allowing for excellent compaction and stability. This blend is typically produced by mechanically crushing larger rocks and screening them to achieve the desired gradation.




The 3/4" to 1" size range provides a balance between load-bearing strength and ease of compaction, making it ideal for use as a sub-base beneath roads, driveways, parking lots, and concrete slabs. The inclusion of fines helps lock the aggregate together, reducing voids and creating a firm, stable surface that resists shifting and settling. While this material is not decorative, its structural reliability and compaction properties make it a preferred choice for both residential and commercial base layers. One consideration is that the presence of fines can reduce drainage compared to clean stone, but it significantly improves stability and support for overlying materials.
