Aggregate industry in the United States

Top crushed rock companies as of 2015, in order of descending tonnage. The top ten companies provided 45 percent of the crushed rock produced in the US.
Most aggregate is used in construction, including 97 percent of sand and gravel and 76 percent of crushed rock. Per capita usage in the United States in 1996 was 8.7 metric tons per year.
Use, and therefore production of aggregate, is determined by the construction industry. Production in 2017 was well below the peak of 3.1 billion tons mined in 2006, during the height of the United States housing bubble.
