Methods of test for soils for civil engineering purposes - Compaction-related tests Ingestion-build-67170 11 Determination of surface hardnessThis part of BS 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 British Standard 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
