摘要

An estimated 715 million metric tons of total aggregates (crushed stone, sand, and gravel combined) was produced and shipped for consumption in the United States in the fourth quarter of 2005, compared with 707 million metric tons in the same period of 2004, according to the latest USGS Mineral Industry Survey. "The estimated 2005 total annual production of aggregates produced for consumption was 2.9 billion metric tons, a 1.8 percent increase compared with 2004," says Jason C. Willett, crushed stone commodity specialist. "That's a new record high." An estimated 405 million metric tons of crushed stone was produced and shipped for consumption in the United States in the fourth quarter of 2005, a slight increase compared with the same period of 2004. The estimated annual production of crushed stone shipped for consumption in 2005 was 1.6 billion metric tons, an increase of 2.5 percent compared with 2004.
