Crushed stone refers to rock deposits that are pulverized by machines to specific shapes and sizes. Along with asphalt and concrete, it ranks high on the list of commonly used landscaping and construction materials. Below is a brief guide to understanding the value of this construction aggregate.

A Guide to Crushed Stone

Materials Used

Different types of rock are used to create crushed stone, including basalt, dolomite, sandstone, granite, trap rock, and scoria. The materials are then placed in stone crushers, where the machines whittle down the rock into desired shapes and sizes for application. Crushed stone looks similar to gravel, but due to its manufacturing process, has sharp edges. Gravel gets its round shape from the natural process of weathering and erosion from exposure to the elements. 

Different Applications

Crushed stone is relatively easy to work with, making it the material of choice for various applications. In residential and commercial landscaping projects, it’s often used as filler for pathways, driveways, and patios. Due to its durability, it’s also used for shoreline protection and as base material for road construction. Gardeners use it as mulch, an alternative to wood, straw, and compost. 

Available Grades 

Crushed stone can range in size from four inches to less than a quarter of an inch. Finer varieties are frequently used as aggregate in asphalt and concrete mix. 

Installation Tips

If you use crushed stone as a surface material in patio or driveway installation, you might end up with stones outside designated areas. Place barricades around the area perimeter to keep the tiny stones in place.
