#4 Stone (3/4″ To 1.5″, Railroad)

#4 Stone Railroad, 3/4” to 1.5”

#4 stone in the 3/4” to 1.5” size range, designated as “Railroad,” is a durable crushed aggregate commonly used in heavy-duty applications. Produced by mechanically crushing larger rocks, this material features angular edges that interlock for enhanced stability. The “Railroad” attribute indicates its suitability for use as track ballast, where strength and drainage are critical.

The larger size range of 3/4” to 1.5” allows for excellent load distribution and prevents shifting under heavy loads, making it ideal for supporting railroad ties and tracks. This size also promotes superior drainage, reducing water accumulation and minimizing frost heave. Beyond rail applications, #4 stone is frequently used in commercial drainage systems, erosion control, and as a base layer for large driveways or parking lots. While its angular shape provides stability, it is less suitable for areas requiring compaction or a smooth finish. Overall, #4 stone railroad aggregate is valued for its strength, drainage properties, and reliability in demanding construction environments.
