Standard Test Methods for Laboratory Compaction ...

Designation: D 698 07e1 Standard Test Methods forLaboratory Compaction Characteristics of Soil UsingStandard Effort (12 400 ft-lbf/ft3(600 kN-m/m3))1 This Standard is issued under the fixed designation D 698; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or Standard has been approved for use by agencies of the Department of Figure 2 was editorially corrected in July Scope* These test Methods cover Laboratory Compaction meth-ods used to determine the relationship between molding watercontent and dry unit weight of soils ( Compaction curve)compacted ina4or6-in.
