What to know
The number describes a grading category, not a rock species. Depending on the source, stone sold as #57 may be limestone, granite or another rock.
Its larger particles are often used in specified drainage or aggregate layers. Drainage behavior also depends on cleanliness, fines, the underlying soils and how the system is designed.
Common project considerations
- Drainage layers where the design calls for this aggregate grading.
- Specified base or subbase layers in some paving systems.
- Projects requiring a coarser stone rather than a dense base blend with fines.
Before you order
- What rock type and actual grading are supplied?
- Is a washed or low-fines product required?
- Does your drainage or paving design call specifically for #57?
