• About IAAP

    The Illinois Association of Aggregate Producers (IAAP) is the trade association representing owners and operators of stone quarries, sand and gravel pits and recycling facilities that produce construction aggregates.  The IAAP has a non-aggregate mining division for companies that produce silica sand, clay, cement and other minerals and mineral products. Finally, the IAAP represents many companies that provide goods and services for the aggregates industry.  In essence, the IAAP represents every sector of Illinois’ non-coal mining industry.

     The purpose of the IAAP is to:

    • solve  common problems of Illinois aggregate producers relating to state specifications for the use of aggregate materials in road construction;

    • work  with state and federal agencies that regulate aggregate mining and reclamation;

    • help educate the general public about the importance of aggregate mining; and 

    • lobby  for state and federal legislation that assist Illinois aggregate producers and fight against legislation that threatens these interests.

    IAAP History

    During the late 1950s, a time when the industry was operating on a piecemeal basis and lacked leadership, a small group of concerned producers gathered to discuss the need for a single organization that would represent all aggregate producers.

    This group recognized that aggregate producers across Illinois were suffering from harmful legislation, difficult specifications, poor communications, inadequate research and a lack of direction.

    The dozen producers who met recognized the need for a united front and representation for their industry and agreed to form an alliance with other interested aggregate producers. From this meeting, the association was organized in 1962.  By 1967,  the needs of the industry had grown to such proportions that it was decided to reorganize the association and  formally incorporate it as a not-for-profit trade association.

    The IAAP responds to statewide aggregate issues that are difficult for national aggregate associations to handle. However, the IAAP works closely with allied Illinois construction associations, with neighboring State aggregate associations and with national industry groups to protect our industry’s future.

    The IAAP currently represents companies producing more than 90 percent of  Illinois's aggregate.  Membership has risen to 100 aggregate and non-aggregate industrial mineral producer companies operating over 250 plants and facilities in 70 counties throughout Illinois as well as operations in Indiana, Iowa, Kentucky, Missouri and Wisconsin.
