March 17, 2011 – Rock Products yesterday was the first aggregates-industry magazine to break the news that final 2010 stone-production numbers, officially released by USGS, were even higher than previous estimates. The estimated annual output of aggregates (crushed stone plus sand and gravel) produced for consumption in 2010 was 2.0 billion metric tons (Gt), a slight increase compared with that of 2009. The previous estimate was 1.977 Gt. Cracking the 2.0 Gt level is a sort of psychological barrier, and given the enormous challenges the market faces, it offers a bit of good news and encouragement moving forward. According to Jason Willett, crushed stone commodity specialist for USGS, the estimated annual output of crushed stone produced for consumption in 2010 was 1.190 billion Gt, a 2 percent increase compared with that of 2009. The previous estimate was 1.177 billion Gt. The estimated U.S. output of construction sand and gravel produced for consumption in 2010 was 820 metric tons (Mt), a 2 percent decrease compared with that of 2009. The previous estimate was 800 million Mt. Onward and upward.
