Crushed stone, one of the most accessible natural resources, is a major basic raw material used by construction, agriculture, and other industries that utilize complex chemical and metallurgical processes. Despite the low value of its basic products, the crushed stone industry is a major contributor to and an indicator of the economic well-being of the Nation.
Crushed stone is used for a wide variety of projects, from building roads to providing suitable drainage and from laying a base for pavers to enhancing the look of landscaping projects. There are so many uses for this versatile material, yet many people are unsure of what size they need when it comes to selecting the proper material for their project.
