• Abstract:
  The several methods of computing stiffness coefficients or elastic moduli of materials to be used in computerized pavement design procedures and in other research activities requiring the knowledge of these values are presented in this report. The methods include computer codes for calculating stiffness coefficients and elastic moduli of simple two-layer pavement structures based on the observed surface pavement deflections, a graphical technique of obtaining elastic moduli of simple two-layer pavement structures and two recently developed computer codes for calculating stiffness coefficients of multilayer pavement structures. The method of solution and the basic equations of each method are presented to assist the prospective user in determining which method best meets these needs.
