Aggregate Base Course, IDOT CA-50, 3/4” Size
Aggregate Base Course with the IDOT CA-50 specification in a 3/4" size range is a high-quality crushed stone blend designed for use as a stable foundation layer in construction projects. Manufactured by crushing and screening durable stone, 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, making it ideal for supporting roadways, driveways, parking lots, and concrete slabs. Its angular shape interlocks well, providing excellent load-bearing capacity and resistance to shifting. The CA-50 gradation ensures minimal voids, reducing settlement and improving long-term stability. While it compacts tightly for a solid base, it still allows for adequate drainage, helping to prevent water accumulation and frost heave. This makes it a preferred choice for both residential and commercial base layers where durability and reliability are essential.Applications & Uses
