Product Specifications
Applications & Uses
Aggregate Base Course - IDOT CA-7/CA-11, 3/4" Size
Aggregate Base Course in the IDOT CA-7 and CA-11 specification, with a 3/4" size range, is a high-quality crushed stone product engineered for strength and stability. Produced by mechanically crushing and screening durable rock, this material meets Illinois Department of Transportation (IDOT) standards, ensuring consistent gradation and performance.
The 3/4" size offers an optimal balance between compaction and drainage. Its angular shape interlocks well, providing a stable base that resists shifting, while the size allows for efficient water movement, reducing the risk of pooling or frost heave. This makes it ideal for use as a sub-base in roadways, parking lots, driveways, and under concrete slabs. The CA-7 and CA-11 designations indicate a clean, well-graded aggregate with minimal fines, resulting in less dust and easier handling. While its excellent drainage and load-bearing properties are major advantages, it may require a finer topping layer for finished surfaces. Suitable for both residential and commercial projects, this aggregate is a reliable choice for foundational construction needs.
