CAT NO: DIDACTICNLE-Export-015052
California Bearing Ratio Test (Field Type).
To know C.B.R. Values in situ, it is useful in determining the load
carrying capacity in the field when in-place density and water contents
are such that the degree of sturation is 80 % or greater,
when material
is conhensionless and coarse grained, such that it is not effected by
changes in water contents and when the material has been in-place for
considerable time. The loading is effected by means of a mechanical load
frames which can be fixed to the under side of a truck.
