B$.$ RESILIENT MODULUS TEST ANALYSIS:

The resilient modulus test data on a subgrade soil sample in table $1$ includes recoverable

deformations $((i\frac{n}{i}n)),$ confining stresses $),$ and deviatoric stresses $).$ The

distance between the LVDT clamps $($deformation measuring device$)$ is $4$ in$.$ Using this data

determine:

a$.M_r$ for each successful loading sequence of confining and deviator stresses

b$.M_r$ equation for all the combinations of confining stresses and loading levels, as a function of the

bulk stress and the deviator stress.

c$.$ Recommend the best values of constants for the right relationship of the $M_r$ equation in $($b$)$ based

on the $R^2$ value. $s$
