The Nation's Top 25 CONSTRUCTION AGGREGATES PRODUCERS 2011 marked the first increase in production since 2006, with slight price increases as well. by Jason Christopher Willett 24 U .S. production of construction aggregates in 2011 was 2.17 billion short tons, valued at $17.2 billion, free on board (f.o.b.) at plant. Construction aggregates production decreased by 37 percent, and the associated value decreased by 25 percent, compared with the record highs reported in 2006. In 2011, construction aggregates production increased for the first time since 2006, owing to a very slight increase in the production of both construction sand and gravel and crushed stone. The average unit value, which is the f.o.b. at plant price of a ton of material, increased slightly, but is still less than the average unit value of two years prior. The U.S. Geological Survey (USGS) defines the construction aggregates industry as those companies that mine and process crushed stone and construction sand and gravel. The construction aggregates industry is active in all 50 states and consists of about 5,400 mining companies that manage more than 10,000 operations. In 2011, the 10 leading construction aggregates-producing states were, in descending order of tonnage, Texas, California, Pennsylvania, Ohio, Missouri, Illinois, New York, Indiana, Virginia, and Kentucky. These 10 states accounted for 44 percent of the national production of construction aggregates, or 955 million short tons. The 25 leading companies, in de- AGGREGATES MANAGER April 2013 scending order of construction aggregates production in 2011, follow. These companies controlled 1,926 active operations throughout the 50 states and accounted for 42 percent of the production and 46 percent of the value of construction aggregates in the United States. The 1,926 active operations mined rock from 1,045 crushed stone quarries and 761 construction sand and gravel pits. The 100 largest construction aggregates operations produced 14 percent of the production of construction aggregates. Of the 315 million short tons of construction aggregates produced by these 100 largest operations, 67 percent was limestone and dolomite and 16 percent was construction sand and gravel. Twenty-four of the largest operations did not report their production or sales to the USGS, and their production was estimated by using employment data provided by the Mine Safety and Health Administration (MSHA). 1.
