Eric Mears Discusses Aggregate Quarrying

America’s infrastructure is built of sand, gravel, and crushed rock; collectively referred to as aggregate. Eric Mears, VP of Haley & Aldrich, addresses aggregate quarrying from the Phoenix area’s Agua Fria River on the latest Arizona Mining Review eVideo Magazine

Aggregate is a primary ingredient in manufacturing concrete used to construct roads, bridges, airports, utilities, buildings, homes, and all other types of infrastructure. According to the US Geological Survey’s 2018 Mineral Commodity report (1), aggregate production in the U.S. topped $23 billion in 2017, falling just south of the $26.3 billion for all U.S. metal mine production.
