Annually, Americans traverse more than 3 trillion miles of roadways, and about 94 percent of those roads are surfaced with asphalt. The asphalt industry connects people to places and employs hundreds of thousands of Americans.
Currently, in the U.S. 343,120 people are employed in the construction of highway, streets, runways, roads, and bridges, with an additional 59,860 operating heavy construction equipment, a further 243,840 people are involved in civil, environmental, and geotechnical engineering, and 111,470 more are employed in the refining sector. Taken together, the Asphalt Institute (AI), the National Asphalt Pavement Association (NAPA), and the State Asphalt Pavement Associations (SAPAs) represent these markets. AI represents 90 percent of the liquid asphalt produced in North America with additional production occurring in international markets. NAPA counts over 1,100 companies as members of the trade association. While the SAPAs represent more than 3,000 companies in 39 states across the nation.
