United States annually. The production of crushed stone aggregates generates, as a by-product, quarry fines. Quarry fines are products that are produced as a result of the crushing operation, containing a large amount of fine material that passes the No. 200 sieve. Quarry fines may be dry screenings collected from below the last screen deck in

Rock quarries usually operate for at least 30 years and are developed in distinct benches or steps. A controlled explosion is normally used to release the rock from the working face. It is then transported by truck or conveyor to a crusher, where it goes through a series of crushing and screening stages to produce a range of final sizes to suit

Crushed aggregate is produced by crushing quarry rock, boulders, cobbles, or large-size gravel. Recycled concrete is a viable source of aggregate and has been satisfactorily used in granular subbases, soil-cement, and in new concrete. After harvesting, aggregate is processed: crushed, screened, and washed to obtain proper cleanliness and gradation.
Crushed aggregate, one-inch crushed concrete, recycled asphalt, 3/8-inch pea gravel, 2-inch sewer filter rock, and concrete and asphalt aggregate blends all weigh in at 1.07 tons. Pit run gravel follows at 1.25 tons per cubic meter, regardless of whether it is 2-inch or 4-inch. The heaviest of the crushed rock selections are Angular Rip Rap and
