Sand and gravel has been, and will continue to be, among the most important construction and industrial materials in the United States. It is the only mineral commodity produced in all 50 States. It is the principal ingredient in many houses, office buildings, highways, dams, airport runways, bridges, canals, and in glass for bottles and house and automobile windows. Also, it has one of the lowest average per ton values of all mineral commodities. To keep the price of sand and gravel low, the general trend is toward larger, more efficient plants, working larger deposits, and keeping the transportation costs to deliver a ton of aggregate at a minimum. This Bureau of Mines report presents comprehensive data on sand and gravel including industry structure, reserves-resources, technology, supply-demand relationships, byproducts and coproducts, economic factors and problems, operating factors and problems, and outlook to 2000.
