The top 20 crushed stone producers accounted for 743 million metric tons, or 55 percent of the 2016 U.S. output, according to a report USGS Commodity Specialist Jason Willet prepared from the most current shipment data available. He also finds that the top 100 operators’ limestone and granite production totaled 1.02 billion mt, or 75 percent of industry shipments, in 2016. The 294 leading companies in his survey, representing 20 percent of operators tracked, were responsible for 1.21 billion mt or 89 percent of output. 

Topping the list of 2016 crushed stone producers are Vulcan Materials Co., Martin Marietta Materials, Oldcastle Materials, Lehigh Hanson Inc. and LafargeHolcim, followed by Cemex USA, Rogers Group, Carmeuse Lime & Stone, Luck Stone and Lhoist North America. Three producers rounding out the top 20 are now part of larger peers: CRH/Oldcastle acquired Ash Grove Cement (12) and Mulzer Crushed Stone (20) in Spring 2017 and 2018 deals, while Martin Marietta closed on Bluegrass Materials (13) earlier this year.
