This Part of SS 1377 describes methods of test for determining characteristics related to the compaction of soils, which can be used as a basis for specifying requirements for soils compacted in the field.
This Part also includes a method for assessing an empirical strength criterion (the CBR value) of a compacted or undisturbed soil used as a sub-grade material for pavement construction.
Reference is made to some of the classification tests described in BS 1377 : Part 2.
Reference is made to BS 1377 : Part 1 for general requirements that are relevant to all Parts of this standard, and for methods of preliminary preparation of soil for testing.
