Abstract
This study carried out the resilient modulus tests with the MTS cyclic triaxial system. After that, the matrix suctions were measured by the filter paper method. Based on the above test results, the characteristics of resilient modulus of unsaturated cohesive subgrade soils were investigated. Experimental results showed that the resilient modulus of unsaturated cohesive subgrade soils reduced with the increase of deviator stress and the decrease of matrix suction. A prediction model incorporating cyclic deviator stress and matrix suction for unsaturated cohesive subgrade soils was established.
