NSSGA is the only group focused solely on the interests of the aggregates industry. Recognized as one of the most active and effective advocacy groups in Washington, D.C., NSSGA ensures that its members’ voices are being heard loud and clear on Capitol Hill.

NSSGA members have grown ROCKPAC into one of the nation’s premier political action committees. It is now ranked number 19 nationally. A PAC of this magnitude commands the attention of politicians not only in Washington, D.C., but also in congressional districts nationwide.


Like most industries, the aggregates industry depends on the know-how and productivity of its workforce. Unlike many industries, aggregates producers have to mix brains and brawn to produce the right products on a timely basis. The brawn can be handled with heavy equipment. The brains come from training and idea-sharing throughout the workforce. NSSGA facilitates that training with:

• AGG1 Aggregates Academy & Expo
• Monthly webinars on a variety of topics
• Professional training courses
• CONEXPO-CON/AGG education program

In a recent survey, more than 80% of members agreed that NSSGA is by far their primary source of industry information.


NSSGA adds significant value to company membership by:

• Holding annual governance and business meetings that bring together senior managers and owners from around the country to discuss common problems, opportunities and developments.
• Encouraging member involvement in areas of specific interest where they can make a positive impact on the industry.
