#57 Stone (#4 To 1″, Unwashed)

#57 Stone, Unwashed, #4 to 1” Size Range

#57 stone in an unwashed, #4 to 1" size range is a versatile crushed aggregate commonly used in construction and landscaping. Produced by mechanically crushing larger rocks, this material features angular pieces that range from approximately 1 inch down to #4 sieve size. The unwashed attribute means the stone retains fine particles and dust from the crushing process, which can affect its performance in certain applications.




The #4 to 1" size range provides excellent drainage while still offering stability, making it suitable for use in base layers for driveways, parking lots, and road construction. The presence of fines in unwashed #57 stone can aid compaction, which is beneficial for creating a solid sub-base. However, the additional dust may not be ideal for decorative or exposed surfaces, and it can contribute to muddy conditions when wet. This material is also commonly used for backfilling, pipe bedding, and erosion control in both residential and commercial projects.
