#57 Stone (#4 To 1″, Fdot, Granite)

#57 Stone - FDOT Granite, #4 to 1” Size Range

#57 stone in the FDOT granite specification, sized from #4 to 1", is a high-quality crushed aggregate produced from durable granite rock. This material is manufactured by mechanically crushing and screening granite to achieve a consistent, angular shape and precise size distribution. The FDOT (Florida Department of Transportation) designation ensures the stone meets strict standards for strength, cleanliness, and performance, making it suitable for demanding construction applications.




The #4 to 1" size range offers excellent drainage properties while providing substantial load-bearing capacity. The angular granite pieces interlock well, making this aggregate ideal for use in road base layers, driveways, parking lots, and drainage systems. It is also commonly used as a sub-base for concrete slabs and as backfill for retaining walls. The granite composition resists weathering and provides long-lasting stability, while the FDOT certification guarantees minimal fines and consistent quality. This size is less suitable for areas requiring tight compaction but excels in applications where drainage and structural support are priorities.
