Figure 3-15. Undisturbed CI readings on samples within the remolding cylinder
procedures used are identical to those previously described for the determination of the undisturbed strength of a
soil within the remolding cylinder (see figure 3-17, page 3-35). Because the value obtained are a result of these
procedure pertain to remolded soils, they are recorded in the "after" column of a chart similar to the one shown in
table 3-5, page 3-34.
Once the required layers (including all critical layers as well as any layer underlying a critical layer in an
abnormal soil profile) have been tested and all corresponding values have been recorded on a chart similar to the
one shown in table 3-5, page 3-34, the values obtained for each test are averaged (see table 3-5, page 3-34). In
order to arrive at the RI of a particular layer of soil, the average CI reading obtained for that soil while it was
within the remolding cylinder following remolding is divided by the average CI reading obtained for the same soil
while it was within the remolding cylinder before remolding. Referring to the soil portrayed in table 3-5, page 3-
34, the RI of the soil layer occurring at a depth of 0 to 6 inches is 0.869
