The quality control procedures for earthwork compaction used by New York State and many others have been to compare in-place density (measured by the sand-cone method) with maximum density (determined by a one-point compaction test and a family of moisture-density curves). This paper describes a new rapid test that uses all these concepts. A time saving is accomplished by a combination of equipment and computation improvements. Through use of a special slide rule, in-place density is obtained from the volume of a hole as measured by a sand replacement volumeter. Maximum densities, taken from the moisture-density curves and compiled in compaction control tables, can be compared with inplace densities without any calculations or interpolations. Moisture determinations are usually not required, and conversions from wet to dry density are never necessary. New York State is now using this system with a high degree of success.
