ABSTRACT: The value of the California bearing ratio (CBR) test is
an index making it possible to evaluate the load of the foundation soil and the
resistance of the pavement materials. The California Bearing Ratio (CBR) of
unsaturated soils is particularly related to their quality. The mechanism
affecting the bearing capacity, in the case of California Bearing Ratio (CBR),
has been studied as a transformation of red clay for the backfill. In this
study, the effect of compaction energy on
compaction characteristics and California Bearing Ratio (CBR) values was investigated. The relationship between the CBR value (California Ratio Ratio) and the
degree of compaction is characterized by a gradual evolution of unsaturated
soils with different water contents. The results show that the compaction
degree and California Bearing Ratio (CBR) value of the soil in the cold region
are insufficient, but the bearing capacity of the compacted soil after
immersion under the maximum dry density can still meet the filling
requirements. The red clays tested are considered useful as bedding in areas of
unsaturated soils.
