Aggregate Base Course (825B)

Aggregate Base Course 825B

Aggregate Base Course with the 825B designation is a high-quality, well-graded blend of crushed stone and fines, engineered for use as a stable foundation layer in construction projects. The "825B" attribute refers to a specific gradation and composition standard, ensuring optimal compaction and load-bearing capacity. This material is typically produced by crushing and screening quarried rock to meet strict specifications for particle size distribution and durability.




The 825B gradation is designed to provide excellent stability and compaction, making it ideal for use under roadways, parking lots, driveways, and building pads. Its blend of coarse and fine particles locks together tightly, minimizing voids and reducing the risk of settling or shifting over time. This base course is valued for its strength, ease of installation, and reliable performance in both residential and commercial applications. While it offers superior support and drainage, it is not intended as a decorative surface layer and should be covered with asphalt, concrete, or pavers for finished projects.
