Reference only#9 Stone (#16 To #4, Ca-6)
#9 stone with a Ca-6 attribute in the #16 to #4 size range is a versatile crushed aggregate commonly used in construction and landscaping.

The Ca-6 designation indicates a well-graded mix that includes both coarse and fine particles, enhancing compaction and stability.
