RESILIENT MODULUS TEST

Performing the Resilient Modulus Test on a material provides a basic relationship between the applied stress and measured deformation of the material, which allows for a structural analysis of layered pavement systems. This test also allows pavement construction materials, including subgrade soils, to be characterized under various conditions and stress states, which can simulate conditions of a pavement that is subjected to traffic loads... The Resilient Modulus Test, put simply, is a modified version of the indirect tension test, where a repeated vertical stress of a fixed magnitude, load duration and cyclic duration is applied to a cylindrical testing specimen. During each load cycle, the vertical stress is applied and removed in a sinusoidal fashion, resulting in a smooth application of the stress. The test specimen is subjected to many of these load cycles in order to accurately simulate traffic loading. The vertical load is applied to the side of a cylindrical specimen rather..
