b. Presentation of Results. Test results should be presented in the form of plots of log MR
versus log of the sum of the principal stresses and <r versus the principal stress ratio (Figure N-5).
The equation of the line for resilient modulus is MR = K12K2 where K1 is the intercept when 2 =
1 psi and K2 is the slope of the line.
