Crushed Stone Ca-16 (IDOT), 1/2” to 1”

Crushed stone Ca-16, approved by IDOT (Illinois Department of Transportation), in a 1/2" to 1" size range is a durable aggregate produced by mechanically crushing larger rocks into angular fragments. This specific gradation ensures a consistent particle size, making it ideal for a variety of construction and infrastructure projects.




The 1/2" to 1" size offers excellent load-bearing capacity and compaction, while the angular shape of the crushed stone provides superior interlocking properties. This combination is especially valued in road base layers, subbase for pavements, and as a stable foundation for driveways, parking lots, and walkways. The Ca-16 specification ensures compliance with state standards, making it a reliable choice for both residential and commercial applications. Its angularity promotes good drainage while minimizing shifting, though it may be less suitable for decorative or barefoot areas due to its rough texture.
