Aggregate Base Course (Type 5, State)

Aggregate Base Course, State-Specified, Type 5

Aggregate Base Course in a Type 5 size range with a state specification is a high-quality blend of crushed stone, gravel, and fines engineered to meet rigorous state standards for road and infrastructure projects. This material is produced by crushing and screening quarried rock to achieve a consistent gradation, ensuring reliable compaction and load-bearing performance.




The Type 5 size range is specifically designed to balance stability and drainage, making it ideal for use as a foundational layer beneath pavements, highways, parking lots, and driveways. Its well-graded composition allows for excellent compaction, reducing the risk of settling and providing a stable base for asphalt or concrete surfaces. The state-specified attribute guarantees compliance with local regulations, ensuring durability and long-term performance. While its dense structure offers superior support, it may be less permeable than coarser aggregates, so it is best suited for applications where strength and stability are prioritized over rapid drainage.
