Crusher run, also known as crush and run or crusher stone, is a type of gravel that is commonly used in construction projects. It is made up of crushed stone and stone dust mixed together, compacted, and then graded. Crusher run is often used as a base material for driveways, roadways, and pathways because it provides a stable foundation and excellent drainage properties. Additionally, it is frequently used as a base for pavers and as backfill around underground pipes and utilities. Its versatility, affordability, and durability make crusher run a popular choice for various construction applications.
