Aggregate Base Course (1.25″ Minus, Top Course)

Aggregate Base Course - Top Course, 1.25” Minus

Aggregate Base Course in a 1.25" minus size, specified as "Top Course," is a well-graded blend of crushed stone, gravel, and fines. The "minus" designation means the material includes particles up to 1.25 inches in diameter, along with smaller particles and fines, resulting in excellent compaction and stability. As a "Top Course," this aggregate is typically used as the final layer in base construction, providing a smooth, dense surface ready for pavement or other finishes.




The 1.25" minus size ensures a tight interlock between particles, reducing voids and creating a solid foundation that resists shifting and settling. This makes it ideal for use under roads, driveways, parking lots, and walkways in both residential and commercial projects. The inclusion of fines enhances compaction but may reduce drainage compared to open-graded aggregates. Overall, this material offers a balance of strength, stability, and ease of installation, making it a preferred choice for load-bearing surfaces.
