#4A Stone (3/4″ Minus, Ballast, Granite)

#4A Stone Ballast Granite, 3/4” Minus

#4A Stone in a 3/4” minus size range is a high-quality granite aggregate specifically graded for ballast applications. Produced by crushing and screening durable granite rock, this material features a mix of angular particles up to 3/4” in size, with smaller fines included. The granite composition ensures excellent hardness and long-term durability, making it suitable for demanding construction environments.

The 3/4” minus sizing offers a balance between stability and compaction. The angular shape locks together well, providing a solid base, while the fines fill gaps for improved compaction and reduced movement. This makes #4A Stone ideal for use as railroad ballast, underlayment for heavy-duty pavements, and as a base material for retaining walls or large paver projects. It is also commonly used in commercial site work where strong load-bearing capacity and drainage are required. The granite attribute means less dust and a cleaner finish compared to softer stone types, though the presence of fines may reduce drainage slightly compared to clean stone. Overall, #4A Stone Ballast Granite, 3/4” minus, is a reliable choice for projects needing strength, stability, and longevity.
