The re-formulated association had the same number of Producer members combined with almost 100 Associate members and 20 trucking companies.
The Association continues to pursue the objectives that were first established in 1967. These objectives are focused on establishing high ethical standards for all industry activities, advocacy with governmental and policy making agencies, educating the to the societal benefits that are provided by this industry and training of industry employees in areas of safety, environmental responsibility and professional management.
The construction aggregate industry is not only the foundation for highways and infrastructure construction but also the foundation for economic growth.
