  1. Annotation: (1) The minimum value is the test value of the dynamic resilient modulus of the sample under the most unfavorable stress conditions (i.e., σ3 = 15 kPa, σd = 30 kPa). (2) The maximum value is the test value of the dynamic resilient modulus of the sample under optimal stress conditions (i.e., σ3 = 80 kPa, σd = 40 kPa). (3) The average value is the average value of the test value of the dynamic resilient modulus of the sample under the 15 stress conditions in Table 4.
