Aggregate Base Course Ca-3, IDOT, 1/2” to 1”
Aggregate Base Course with a Ca-3, IDOT specification in a 1/2" to 1" size range is a high-quality crushed stone blend designed for foundational support in construction projects. Produced by crushing and screening durable stone, this material meets Illinois Department of Transportation (IDOT) standards, ensuring consistent gradation and performance.
The 1/2" to 1" size range offers an optimal balance between compaction and drainage, making it ideal for use as a stable subbase beneath roads, driveways, parking lots, and concrete slabs. The Ca-3 grading ensures the aggregate locks together well, providing excellent load-bearing capacity while minimizing settlement. This size is less prone to shifting than finer materials, yet still allows for adequate water movement, reducing the risk of frost heave and erosion. Commonly used in both residential and commercial applications, Aggregate Base Course Ca-3 is valued for its durability, ease of installation, and compliance with strict construction standards.Applications & Uses
