Aggregate Base Course (3/8″ Minus, Dense, Grade)

Aggregate Base Course, Dense Grade, 3/8” Minus

Aggregate Base Course in a dense grade and 3/8" minus size range is a compactable blend of crushed stone, gravel, and fines. The "dense grade" attribute means the material contains a well-graded mix of particle sizes, including fine particles that fill voids between larger stones. The "3/8" minus" specification indicates that the largest particles are 3/8 inch in diameter, with smaller sizes and fines included.




This combination results in a stable, tightly packed base material that is ideal for load-bearing applications. The fine content allows for excellent compaction, reducing the risk of settling and providing a solid foundation. Common uses include sub-base layers for driveways, walkways, patios, and road construction, as well as under pavers and concrete slabs. The main advantage of this material is its ability to create a smooth, stable surface with minimal voids, though it may not provide as much drainage as more open-graded aggregates.
