Aggregate Base Course (3/4″ To 1.5″, Ca-6, Idot, Grade 8)

Aggregate Base Course - Ca-6, IDOT, Grade 8, 3/4” to 1.5”

Aggregate Base Course with Ca-6, IDOT, Grade 8 specifications in a 3/4” to 1.5” size range is a high-quality crushed stone blend designed for superior compaction and load-bearing performance. Produced by mechanically crushing and screening quarried stone, this material meets strict Illinois Department of Transportation (IDOT) standards, ensuring consistency and reliability for demanding construction projects.

The 3/4” to 1.5” size range offers an optimal balance between particle interlock and drainage, making it ideal for use as a stable subbase beneath roads, driveways, parking lots, and concrete slabs. The Ca-6 and Grade 8 attributes indicate a well-graded mix with fines, which enhances compaction and reduces voids, resulting in a firm, durable foundation. This material is also commonly used for pathways, patios, and as a base for pavers in both residential and commercial settings.

Pros include excellent load distribution, reduced settling, and reliable drainage. The presence of fines allows for easy compaction, but may generate some dust during installation. Overall, this aggregate base course is a trusted choice for projects requiring a strong, stable, and long-lasting base layer.
