Aggregate Base Course (1.5″, Idot, Ca-2)
Applications & Uses
Aggregate Base Course, IDOT CA-2, 1.5" Size Range
Aggregate Base Course with the IDOT CA-2 specification in a 1.5" size range is a durable, crushed stone material engineered for foundational strength and stability. Produced by mechanically crushing and screening quarried rock, this aggregate meets Illinois Department of Transportation (IDOT) standards, ensuring consistent quality and performance for demanding construction applications.
The 1.5" size range provides excellent load-bearing capacity and compaction, making it ideal for use as a subbase beneath roads, parking lots, and driveways. Its larger particle size allows for superior drainage and resistance to shifting, which is especially important in heavy-traffic or freeze-thaw environments. While its coarser texture may not be suitable for finished surfaces, it excels as a stable foundation layer in both residential and commercial projects. The IDOT CA-2 designation guarantees reliable gradation and minimal fines, reducing dust and improving long-term performance.
