AGGREGATES PRODUCERS The Nation's Top 25 CONSTRUCTION IN 2010, THE MARKET APPEARED TO BOTTOM OUT WITH PRODUCTION CONTINUING ITS DOWNWARD TREND AND AVERAGE UNIT VALUES DOWN FOR THE FIRST TIME SINCE 1998. .S. production of construc- tion aggregates in 2010 was 2.14 billion short tons val- ued at $17 billion, free on board (f.o.b.) at plant. Construction aggregates production decreased by 37 percent, and the associated value decreased by 26 percent compared with the record highs reported in 2006. In 2010, construction aggre- gates production decreased for the fourth consecutive time owing to a 6-percent decrease in the production of construction sand and gravel and a slight decrease in the production of crushed stone. The average unit val- ue, which is the free on board at the plant price of a ton of material, de- creased for the first time since 1998. There have been only three decreases on record since 1950. U by Jason Christopher Willett and Wallace P. Bolen The U.S. Geological Survey (USGS) defines the construction ag- gregates 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 opera- tions. In 2010, the 10 leading con- struction aggregates-producing states were, in descending order of tonnage, Texas, California, Pennsylvania, Mis- souri, Ohio, Illinois, Indiana, New York, Michigan, and Florida. These 10 states accounted for 44 percent of the national production of con- struction aggregates, or 935 million short tons. The 25 leading companies, in order of construction aggregates production in 2010, follow. These companies controlled 1,911 active operations throughout the 50 states and accounted for 41 percent of the production and 45 percent of the value of construction aggregates in the United States. The 1,911 active operations mined rock from 1,039 crushed stone quarries and 743 construction sand and gravel pits. The 100 largest construction aggregates operations produced 14 percent of the production of construction aggregates. Of the 291 million short tons of construction aggregates produced by these 100 largest operations, 68 percent was limestone and dolomite and 14 percent was construction sand and gravel. Sixteen of the largest opera- tions did not report their produc- tion or sales to the USGS, and their production was estimated by using employment data provided by the Mine Safety and Health Adminis- tration (MSHA). 1.
