The resilient modulus, M R , of subgrade soils had been used extensively as an important unbound material property in the pavement design and analysis. The stress state and the humidity of cohesive soils have significant impacts on the resilient modulus. To predict the resilient modulus of cohesive soils in South China, the material indicator tests, an improved repeated load triaxial test and the pressure plate test were carried out. Then the SWCC was described using the Fredlund and Xing’s model with a relatively high coefficient of determina...
