Aggregates and asphalt are combined in a mixing facility in which all of the constituent materials are heated, proportioned and mixed to produce the desired paving mixture. After plant mixing is complete, the hot mix is transported to the paving site and spread with a paving machine in a loosely compacted layer to a uniform, even surface.
Crushed aggregate is produced by crushing quarry rock, boulders, cobbles, or largesize gravel. Recycled concrete is a viable source of aggregate and has been satisfactorily used in granular subbases, soilcement, and in new concrete. After harvesting, aggregate is processed crushed, screened, and washed to obtain proper cleanliness and gradation.
