• Abstract:
  The determination of the elastic, or Young's, modulus, E, of the materials in each layer in an n-layered pavement system given the number, order, thicknesses, and Poisson's ratios of the layers, and the surface load and deflection data, is not possible using the classical theory of elasticity alone. This report develops some assumptions and techniques, based on the effective modulus concept, Burmister's deflection equation, the finite element method, and the concepts of beams and plates on elastic foundations, which yield mathematical solutions for such moduli.
