Aggregate Base Course (Caltrans)
Applications & Uses
Aggregate Base Course - Caltrans Specification
Aggregate Base Course meeting Caltrans specifications is a high-quality blend of crushed stone, gravel, and sand engineered for use as a foundational layer in road and pavement construction. Manufactured to strict standards, this material ensures optimal compaction, stability, and load-bearing capacity, making it a preferred choice for projects requiring compliance with California Department of Transportation (Caltrans) guidelines.
The Caltrans attribute signifies that the aggregate meets rigorous gradation, durability, and cleanliness requirements, resulting in a base material that resists shifting and settlement under heavy traffic. This makes it ideal for use beneath highways, streets, parking lots, and airport runways, as well as for residential driveways and walkways where long-term performance is critical. The well-graded composition promotes excellent compaction and drainage, reducing the risk of surface cracking and water-related damage. While its engineered properties may make it less decorative than other aggregates, its reliability and strength are unmatched for structural applications.
