THEORETICAL RELATIONSHIPS BETWEEN MODULI FOR SOIL LAYERS BENEATH CONCRETE PAVEMENTS

Several mathematical relationships are presented which relate the Westergaard method of analysis used for rigid pavements and the elastic layer method of analysis used for both rigid and flexible pavements. Twenty-three pavement sections were selected to illustrate the usage of these relationships. These sections represent the widest possible variation of rigid pavement types for which sufficient materials data was available. For the sections studied and within the context of linear analysis, these relationships demonstrate that the peak pavement stress can usually be computed by either method of analysis while the peak displacements are separated by a rather consistent seventy percent.
