4.54-kg (10-lb) Rammer and a 457-mm
(18-in.) Drop
AASHTO Designation: T 180-01 (2004)
SCOPE
1.1.This method oftest is intended for determining the relationship between the moisture content and
density of soils when compacted in a given mold of a given size with a 4.54-kg (10-lb) rammer dropped from a height of 457 mm (18 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 IOI.60-mm (4-in.) mold: Soil material passing a 19.0-mm (314-in.) sieve
Sections 8 and 9.
- MethodD-A 152.40-mm (6-in.) mold: Soil material passing a 19.0-mm (314-in.) sieve
Sections 10 and 11.
