scope:
These methods of test are intended for determining the relation between the moisture content and density of soils compacted in a mold of a given size with a 2.5-kg (5.5-lb) rammer dropped from a height of 305 mm (12 in.). Four alternate procedures are provided as follows:
Method A-A 101.60-mm (4-in.) mold: Soil material passing a 4.75-mm (No. 4) sieve Sections 4 and 5.
Method B-A 152.40-mm (6-in.) mold: Soil material passing a 4.75-mm (No. 4) sieve Sections 6 and 7.
Method C-A 101.60-mm (4-in.) mold: Soil material passing a 19.0-mm (3/4-in.) sieve Sections 8 and9.
Method D-A 152.40-mm (6-in.) mold: Soil material passing a 19.0-mm (3/4-in.) sieve Sections 10 and 11.
