In real project, the guidelines for deformation control during track subgrade construction are generally based on the method of setting a reserved settlement amount.Thus, detailed understanding and characterization of the deformation behavior of subgrade soils are a prerequisite for both the construction and subsequent maintenance of railway substructure.To evaluate the effects of the cyclic stress amplitude, initial mean stress, and initial stress ratio on the permanent axial deformation, six series of repeated load triaxial tests were performed.

Increased wheel loads and speeds of freight rail traffic are accelerating the track deterioration of railway lines.

Simple empirical relationships to estimate the dynamic shear modulus and damping ratio was formulated and compared with the similar empirical relationships proposed in the literature.
