Aggregate Base Course (3/8″, Fdot)

Aggregate Base Course, FDOT, 3/8” Size Range

Aggregate Base Course in a 3/8" size range with FDOT (Florida Department of Transportation) certification is a high-quality, compactable material commonly used as a foundational layer in roadways, driveways, and parking lots. Produced by crushing and screening natural stone or gravel, this aggregate meets strict FDOT standards for gradation, durability, and performance, ensuring reliable results for both residential and commercial projects.




The 3/8" size offers an optimal balance between compaction and drainage, making it ideal for creating stable sub-bases that resist shifting and settlement. Its fine gradation allows for tight packing, which enhances load-bearing capacity and minimizes voids, while still permitting adequate water movement to prevent pooling. This makes it especially suitable for use beneath asphalt, concrete, pavers, and other surface materials. The FDOT attribute guarantees consistent quality and compliance with state specifications, making it a preferred choice for public infrastructure and high-traffic areas. Pros include excellent compaction, reliable performance, and regulatory approval; however, the finer size may require careful moisture control during installation to achieve maximum density.
