Limestone SB2 is a dense, well-graded crushed stone base material made up of stone dust up to 1.5 inch aggregate, often referred to as 1.5 inch to fines. This compactable blend locks tightly under pressure to create a strong, stable foundation with high load-bearing capacity. SB2 limestone is widely used in heavy-duty construction where long-term durability, resistance to rutting, and structural stability are essential.
Common applications for limestone SB2
- Road base and highway sub-base construction
