- Written by Mark Kuhar
January 24, 2011 – According to Jason Willett, crushed stone commodity specialist for USGS, in 2010, crushed stone valued at $11 billion was produced by 1,600 companies operating 4,000 quarries, 91 underground mines, and 195 sales/distribution yards in 50 States. Estimated production for 2010 was 1.150 billion metric tons, down slightly from 2009. The information was just released as part of the agency’s 2011 Mineral Commodity Surveys. Leading states, in descending order of production, were Texas, Pennsylvania, Missouri, Illinois, Florida, Georgia, Kentucky, Indiana, Ohio and Virginia, together accounting for 50 percent of the total crushed stone output. Of the total crushed stone produced in 2010, about 68 percent was limestone and dolomite; 13 percent, granite; 7 percent, miscellaneous stone; 6 percent, traprock; and the remaining 6 percent was divided, in descending order of tonnage, among sandstone and quartzite, volcanic cinder and scoria, marble, calcareous marl, slate, and shell. It is estimated that of the 1.19 billion tons of crushed stone consumed in theUnited States in 2010, 44 percent was reported by use, 26 percent was reported for unspecified uses, and 30 percent of the total consumed was estimated for non-respondents to USGS canvasses. Of the 508 million tons reported by use, 82 percent was used as construction material, mostly for road construction and maintenance; 10 percent, for cement manufacturing; 2 percent each, for lime manufacturing and for agricultural uses; and 4 percent, for special and miscellaneous uses and products.
