#57 Stone (#4 To 1″, Washed, Astm)

#57 Stone, Washed, ASTM, Size Range: #4 to 1”

#57 stone in a washed, ASTM-certified form and a size range of #4 to 1" is a versatile crushed aggregate commonly used in construction. Produced by crushing and screening natural rock, this material is then thoroughly washed to remove dust, clay, and other impurities, ensuring a clean, high-quality product that meets ASTM standards for consistency and performance.




The #4 to 1" size range offers excellent drainage properties while providing stable support, making it ideal for use in driveways, drainage systems, septic fields, and as a base for concrete slabs or roadways. The washing process reduces dust and fines, minimizing compaction and improving drainage-key benefits for applications where water flow is critical. ASTM certification ensures reliable gradation and quality, making this aggregate a preferred choice for both residential and commercial projects. While its angular shape helps lock pieces together for stability, the lack of fines means it is not suitable for areas requiring tight compaction.
