Effect of stiffness modulus and dynamic loading on pavement subgrade

An optimum pavement structure design requires characterization of materials under traffic loading. Investigation of stress-strain relationship of materials, under traffic loading is advised to determine the appropriate stiffness modulus. Since stiffness modulus is extensively dependent to loading dynamics, the loading parameters in the laboratory testing condition should simulate the field condition as close as...
