On September 18, 1970, William F. Childs, III, Richard H. Bowden and Henry F. Coudon, Jr., convened a meeting of 17 producers in the Harry T. Campbell & Sons' Company board room to discuss the possible formation of a state association to represent the interests of the aggregate producers in Maryland. Introduction of severance tax legislation in Annapolis was the catalyst.

The minutes of that first meeting reflect that the proposed association was to take the place of its defunct predecessor, The Maryland Aggregates Tabulation Service. The Tabulation Service, formed to bring highway contractors and material producers together after the National Reconstruction Act era, was formed as a result of a meeting called by William F. Childs, Jr., the Chief Engineer of the Maryland State Roads Commission. The Tabulation Service was never incorporated and had no formal structure. It was guided by a four-man executive committee with Mr. Allen Barton as President along with Mr. Wesley Gatch, Mr. Robert Caruthers and Mr. Guy Campbell.

Dues in the original Tabulation Service were set at $12.50 per month. $5,653.99 was in the bank account of the Tabulation Service. The founding members anticipated some problems in transferring these funds to a new corporation. Lee Thomas of Royston, Mueller, Thomas & McLean attended the meeting and was asked to research this issue as well as draw up Articles of Incorporation and Bylaws.

The 17 companies represented that day voted unanimously to proceed with the incorporation of the MAA. Thus was born the Maryland Aggregates Association, Inc. The exact dues amount was not established during this initial meeting but there seemed to be a consensus that a flat fee of $450.00 per year would be an equitable amount.

Ultimately, the initial dues amount was established at $300 for regular producer members and $150 for associate members. Although it appears as though the founding fathers anticipated having associate members, it was not until 1991 that the board voted to allow associates to join MAA.

The Articles of Incorporation were officially filed and the organization became a legal Maryland corporation on October 5, 1970.
