What is NAPA?

The National Asphalt Pavement Association (NAPA) is the only trade association that exclusively represents the interests of the asphalt producer/contractor on the national level with Congress, government agencies, and other national trade and business organizations. NAPA supports an active research program designed to improve the quality of asphalt pavements and paving techniques used in the construction of roads, streets, highways, parking lots, airports, and environmental and recreational facilities. The association provides technical, educational, and marketing materials and information to its members; supplies product information to users and specifiers of paving materials; and offers educational opportunities. The association, which counts more than 1,100 companies as members, was founded in 1955.

What are asphalt pavements?

Asphalt pavements consist of a combination of approximately 95 percent stone, sand, or gravel bound together by 5 percent asphalt binder, a byproduct of crude oil. Recycled materials, including reclaimed asphalt pavement from old roads and parking lots, are often used to replace some of the virgin aggregate and asphalt binder in pavement mixtures. Asphalt binder is heated and mixed with the aggregate at an asphalt mixture production facility. The resulting asphalt pavement material is loaded into trucks for transport to a paving site. The trucks dump the pavement material into hoppers at the front of a paving machine, which places the material in the roadway. The material is then compacted using heavy rollers. Traffic is generally permitted on the pavement as soon as the pavement has cooled.
