Aggregate Base Course (3″ Minus, Subbase)

Aggregate Base Course, Subbase, 3” Minus

Aggregate Base Course in a 3" minus size range is a foundational construction material composed of crushed stone, gravel, and fines. The "3" minus" designation means the material contains particles up to 3 inches in diameter, with smaller pieces and fines filling the gaps. This blend is specifically engineered for use as a subbase, providing a stable and supportive layer beneath roads, driveways, parking lots, and building pads.




The larger particle size of 3" minus aggregate allows for excellent load distribution and compaction, making it ideal for heavy-duty applications where strength and durability are critical. The inclusion of fines helps the material compact tightly, reducing voids and creating a solid, stable base that resists shifting and settling over time. Commonly used in both residential and commercial projects, this subbase material is essential for ensuring long-lasting pavement and structural performance. While its coarse texture and size make it less suitable for decorative or surface applications, it excels in foundational roles where robust support is required.
