Using a 2.5-kg (5.5-lb) Rammer and a
305-mm (12-in.) Drop
AASHTO Designation:T 99-01 (2004)
SCOPE
1.1.These methods oftest 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 of305 mm (12 in.). Four alternate procedures are provided as follows:
- MethodA-A 101.60-mm (4-in.) mold: Soil material passing a 4.75-mm (No. 4) sieve
Sections 4 and 5.
- MethodB-A 152.40-mm (6-in.) mold: Soil material passing a 4.75-mm (No. 4) sieve
Sections 6 and 7.
- MethodC-A 101.60-mm (4-in.) mold: Soil material passing a 19.0-mm (314-in.) sieve
Sections 8 and9.
- MethodD-A 152.40-mm (6-in.) mold: Soil material passing a 19.0-mm (314-in.) sieve
Sections 10 and 11.
