What is asphalt pavement?
Asphalt pavement is a combination of approximately 95 percent stone, sand, or gravel bound together by 5 percent asphalt cement, a product of crude oil. Asphalt cement is heated and mixed with the aggregate at a mixing facility. The resulting asphalt pavement material is loaded into trucks for transport to the paving site. The trucks dump the pavement material into hoppers located at the front of paving machines. The asphalt is placed, then compacted using a heavy roller, which is driven over the asphalt. Traffic is generally permitted on the pavement as soon as the pavement has cooled.
