Limestone: A sedimentary rock and the most commonly used rock type for crushed stone in the United States. One of the most versatile rocks for construction, limestone is able to be crushed easily, making it a primary rock used in ready-mix concrete, road construction, and railroads. It is widely available in quarries across the country.

Generally underlain by poorly consolidated to well-consolidated sandstone, shale and limestone, with the sandstone and shale being most prevalent and most extensive. In places, the rock units contain significant amounts of gypsum or halite. The soft sandstone and shale tend to afford poor quality crushed stone. Sand and Gravel Resources

"The other big component is the hardness of the material. Usually, water-worn rock, especially [like what we have] here where we have good hard rock sources—is a very durable material and we're fortunate to have that available in large quantities," Chaney says, noting that hard rock is a different category of aggregate than gravel.
