THREE-DIMENSIONAL TESTING AND MODELING OF BALLAST

A series of truly triaxial tests were performed on two sizes of a railroad ballast under different stress paths and with a constant (initial) field density. The results can permit development of nonlinear elastic and plasticity constitutive models. The commonly used resilient modulus model and a variable moduli model were developed as simplified characterization. The behavior of the ballast was found to be dependent on the state of stress, stress paths and particle size.
