Crushed rock refers to a type of rock that has been mechanically broken down into smaller pieces. It is commonly used in construction, landscaping, and road-building projects. The rock is typically obtained from quarries or mining operations, where large rocks are blasted and then crushed into various sizes using powerful machinery such as crushers and screens.
Crushed rock can come in a variety of sizes, ranging from small pebbles to larger stones. It is commonly categorized into two main types: gravel and stone. Gravel refers to the smaller particles, usually less than 2.5 inches (6.35 centimeters) in diameter, while stone typically refers to larger rocks that are 2.5 inches (6.35 centimeters) or larger.
This type of rock is highly versatile and has numerous applications. In construction, crushed rock is a key component in the production of concrete, asphalt, and building foundations. Its rough texture provides stability and enhances the strength of these materials.
In landscaping, crushed rock can be used as a decorative element in gardens, pathways, or as a base layer for other landscape features such as patios or retaining walls. It can also be used for drainage purposes, preventing water accumulation and erosion.
Furthermore, crushed rock is often utilized in road construction projects. It is commonly used as a base layer or sub-base layer beneath asphalt or concrete pavements. The compacted rock provides stability, improves drainage, and enhances the overall durability of the road surface.
Overall, crushed rock is a crucial and versatile material that plays a vital role in various industries, including construction, landscaping, and road-building.
