The Illinois Asphalt Pavement Association (IAPA) is a nonprofit 501(c)(6) trade association composed of Hot Mix Asphalt producers serving the Illinois market and affiliated companies. Since our founding in 1938, IAPA has been serving as an industry resource and a vital communications channel for those involved in virtually every facet of the asphalt industry in Illinois. Originally, the organization was known as the Illinois Bituminous Distributors. In 1941, the name was changed to the Illinois Blacktop Roads Association and ultimately, renamed the Illinois Asphalt Pavement Association in 1967.

The MISSION of IAPA is to:

  • Promote the improvement and advancement of quality asphalt pavement construction in Illinois;
  • Provide assistance to members in the areas of research, technical specifications, environmental issues, education, promotion, government relations, and other related areas; and
  • Educate potential owners and designers of asphalt pavements as to the pavement's characteristics and benefits.
