#1A Stone (1/4″ To 3/4″, High Friction)

#1A Stone, High Friction, 1/4” to 3/4”

#1A stone in a 1/4" to 3/4" size range with high friction properties is a crushed aggregate commonly produced from durable natural rock. The high friction attribute means the stone surfaces are angular and rough, enhancing grip and stability when used in construction applications.




The 1/4" to 3/4" size range makes this material ideal for projects requiring both compaction and effective drainage. The angular, high-friction texture helps lock the stones together, reducing movement and providing a stable base. This makes #1A stone especially suitable for use in roadways, walkways, and as a base layer for pavers or concrete slabs. It is also frequently used in high-traction surfaces such as driveways, parking lots, and areas where slip resistance is important.




Pros of this material include excellent load-bearing capacity, reduced slippage, and improved safety in wet or icy conditions. However, the angular texture can make it less comfortable for barefoot use and slightly harder to spread evenly compared to rounded aggregates. Overall, #1A high friction stone is a reliable choice for both residential and commercial projects where stability and traction are priorities.
