Aggregate Base Course - Ca-7, IDOT, 3/8” to 1.5”
Aggregate Base Course with a Ca-7, IDOT specification in a 3/8" to 1.5" size range is a high-quality crushed stone blend designed for use as a stable foundation layer in construction projects. Produced by mechanically crushing and screening durable stone, this material meets Illinois Department of Transportation (IDOT) standards, ensuring consistent gradation and performance.
The 3/8" to 1.5" size range offers an optimal balance between compaction and drainage. The larger particles provide structural strength, while the smaller sizes fill voids for a dense, stable base. This makes it ideal for use under roadways, driveways, parking lots, and concrete slabs, as well as for sub-base layers in commercial and residential construction. The Ca-7 specification ensures minimal fines, reducing dust and improving drainage, but may require additional compaction effort compared to finer materials. Overall, this aggregate base course is valued for its durability, load-bearing capacity, and reliable performance in demanding applications.Applications & Uses
