3A STONE
Reference only#3A Stone (3/4″ To 1.5″, Modified)
#3A Modified Stone in a 3/4" to 1.5" size range is a versatile crushed aggregate blend, engineered for optimal compaction and stability. The "modified" attribute means this material contains a mix of stone sizes along with stone dust, which fills voids and locks the aggregate together when compacted. This combination results in a dense, stable base that resists shifting and settling.
