Compaction control with a dynamic cone penetrometer

The compaction control consists in measuring the dry density and compares it with the standard Proctor density. The cone resistance in a known granular medium is directly linked to the dry density. It is the comparison between the in-situ penetrogram and a reference curve which permits the compaction. This reference curve corresponds, for a given soil and a required compaction level to the cone resistance (for a passed compaction). A calibration process is necessary to establishes the reference curves. This paper sets out the compaction control method and the calibration Process.
