Aggregate Base Course - Subbase, Modified

Aggregate Base Course with a subbase, modified attribute is a foundational construction material engineered for superior load-bearing and stability. This material is typically produced by blending crushed stone, gravel, and fines to create a dense, well-graded mixture. The "modified" designation indicates that the aggregate has been enhanced-often with additional fines or binders-to improve compaction and structural integrity.




The subbase, modified aggregate is ideal for use beneath roadways, parking lots, driveways, and concrete slabs, where a stable, compacted layer is essential for long-term performance. Its composition allows for excellent load distribution and resistance to shifting or settling, making it a preferred choice for both residential and commercial projects. While its dense nature provides outstanding support, it may be less permeable than open-graded alternatives, so it is best used where drainage is managed or less critical. Overall, this material offers reliable strength and durability for demanding base applications.
