Product Overview
#2 Coarse Aggregate
Large crushed limestone used for structural base and stabilization applications where strength and load support are required. Its size promotes drainage and resists movement under heavy loads, making it suitable for foundational layers. Performance depends on placement depth, subgrade conditions, and whether a topping layer is added.
Why This Material Works
The larger stone size allows water to move freely while providing a strong structural base. This helps reduce settling and supports heavy loads in stabilization and base applications.
Common Applications
- Ground stabilization
- Road base and build-up layers
- Heavy-duty access areas
Material Characteristics
- Large stone for structural support
- Handles heavy loads effectively
- Promotes drainage in base applications
Planning Notes
#2 is not intended as a finish surface. It is commonly used as a lower foundation layer and may require topping with smaller material depending on the application and desired surface.
