4A STONE
Reference only#4A Stone (3/4″ Minus, Ballast)
#4A stone ballast in a 3/4” minus size range is a durable, crushed aggregate commonly used in heavy-duty construction and infrastructure projects. Produced by mechanically crushing larger rocks, this material features a blend of stone pieces up to 3/4” in diameter, along with smaller particles and fines. The “minus” designation means the mix includes everything from the maximum size down to dust, resulting in excellent compaction properties.
