Aggregate Base Course, Udot, 1.5” Size

Aggregate Base Course with a Udot specification in a 1.5" size range is a high-quality, engineered blend of crushed stone and fines designed for use as a stable foundation layer in roadways, parking lots, and other heavy-duty surfaces. The Udot attribute indicates that this material meets the Utah Department of Transportation's rigorous standards for gradation, durability, and compaction, ensuring reliable performance in demanding applications.




The 1.5" size range provides excellent load-bearing capacity and compaction, making it ideal for supporting asphalt or concrete pavements. Its angular particles interlock tightly, reducing movement and settlement over time. Commonly used in both residential and commercial projects, this aggregate base is perfect for driveways, road sub-bases, and structural pads. While its coarser size offers superior drainage and stability, it may require a finer top layer for smoother finishes. Overall, Aggregate Base Course Udot 1.5" is a trusted choice for long-lasting, structurally sound foundations.
