RESILIENT MODULUS OF COHESIVE SOILS

Resilient modulus tests were performed on three clayey subgrade soils with repeated-loading triaxial test equipment. For the laboratory-comp acted samples, stress at 1% axial strain from the conventional unconfi ned compression test (S-u1.0%,) was found to be a good indicator of th e resilient modulus (M(R)). An empirical correlation between laborator y-compacted M(R) and S-u1.0% was developed and was found to be applica ble for the different cohesive soils tested. Data suggest that the M(R ) and S-u1.0% relationship applies to field-compacted specimens as wel l.
