Aggregate Base Course (Subbase, Commercial)

Aggregate Base Course for Commercial Subbase Applications

Aggregate Base Course, commonly referred to as ABC, is a foundational construction material composed of crushed stone, gravel, or recycled concrete. Engineered for strength and stability, it serves as a critical subbase layer beneath roads, parking lots, and large commercial structures. The material is produced by mechanically crushing and screening raw aggregates to create a well-graded blend that compacts tightly, providing a solid and durable foundation.




As a subbase in commercial projects, Aggregate Base Course is valued for its excellent load-bearing capacity and ability to distribute weight evenly, reducing the risk of settling or shifting over time. Its composition allows for effective drainage while maintaining compaction, making it ideal for high-traffic areas and heavy-duty surfaces. Common applications include roadways, industrial yards, and under concrete slabs. The main advantage of using ABC as a subbase is its reliability and performance in supporting large-scale infrastructure, though it typically requires mechanical compaction equipment for optimal results.
