Road Base (IDOT, CA-6) - 3/4” to 1.5”
Road Base with the IDOT CA-6 specification in a 3/4" to 1.5" size range is a well-graded aggregate blend commonly used as a foundational layer in construction projects. This material is typically produced by crushing and screening limestone or gravel to meet strict state standards, ensuring a mix of angular stone and fines for optimal compaction.
The 3/4" to 1.5" size range provides excellent load-bearing capacity and stability, making it ideal for use under roads, driveways, parking lots, and patios. The CA-6 grading ensures a balance between larger aggregate for strength and smaller particles for tight compaction, reducing voids and minimizing settling over time. This combination is valued for its durability, ease of installation, and reliable performance in both residential and commercial applications. While its angular nature aids in interlocking and stability, it may be less suitable for decorative or barefoot areas due to its rough texture.Applications & Uses
