摘要

The estimated production during 2000 of construction aggregates, crushed stone, and construction sand and gravel increased by about 2.6 percent to 2.7 Gt (3 billion st), compared with 1999. The expansion that started in 1992 continued with record production levels for the ninth consecutive year. By commodity, construction sand and gravel production increased by 4.5 percent to 1.16 Gt (1.28 billion st), while crushed stone production increased by 1.3 percent to 1.56 Gt (1.72 billion st).The leading construction aggregates producing states, in order of production during 2000, were Texas, California, Ohio, Florida and Michigan. Their combined production accounted for about 30 percent of US output.
