Example Recommendations for Compaction Specifications The following examples are provided as general reference guidance for geotechnical engineers and civil engineers to use when developing their Recommendations or Compaction Specifications for the design phase. I. Compaction Control Specifications : A. Conventional Option with Site Control This recommendation applies the standard Compaction (M-D control) spec to the moisture-density curves the site is compacting on, and keeps the select lab reference curves as minimum density reference standards. Compact [select from 8-12 ] loose lifts to a minimum of [select from 90% - 98%] of the maximum dry-density and within [select dry % to wet %, or wet of optimum range] of the optimum moisture content on the moisture-density curve of the site lift at full Compaction , as generated by each soil-compactor-lift thickness combination used for each fill lift.
