Aggregate Base Course (Class 5 (#200 To 1.5″), Modified, Limestone)

Aggregate Base Course, Modified Limestone, Class 5 (#200 to 1.5”)

Aggregate Base Course in a Class 5 size range (#200 to 1.5") is a well-graded blend of crushed limestone particles, engineered for optimal compaction and stability. The "modified" attribute indicates that the material has been processed to meet specific gradation and performance standards, ensuring a consistent mix of fine and coarse particles. This combination enhances load-bearing capacity and minimizes voids, making it an ideal sub-base for a variety of construction projects.




The wide size range-from fine particles passing the #200 sieve up to 1.5" stones-allows for excellent compaction and interlock, reducing settlement and providing a stable foundation. Modified limestone is particularly valued for its durability and resistance to moisture, which helps prevent shifting and washouts. Common applications include road and driveway bases, parking lots, walkways, and under concrete slabs. While its dense composition offers superior support and longevity, it may be less permeable than open-graded aggregates, making it best suited for areas where drainage is managed separately.
