Mix designs are not typically required for FDR using pulverization or mechanical stabilization. Testing typically consists of determining the optimum moisture content and maximum dry density using standard or modified Proctor moisture-density tests for use in compaction quality control.
Mix designs are recommended for all bituminous and cementitious stabilized FDR applications. Adjustments may be required in the field to the stabilizing agent design content to obtain optimum performance. If materials vary along the project, more than one mix design may be required. See ARRA publication FDR201A for mix design procedures with emulsified asphalt and FDR202 for cementitious FDR mix design procedures. Regardless of the stabilizing agent used, FDR mix designs should include the following general procedures:
