Backcalculated pavement properties for the arbitrary HMA and PCC Sections (known depth to rigid layer). The most commonly backcalculated property is the elastic modulus of each layer. This conference was arranged by the International Society for Asphalt Pavements. various pavement layer properties can be backcalculated and evaluated.The results showed that backcalculated moduli could sometimes be estimated even in the case where an appropriate solution could not be obtained by conventional backcalculation methods. It was found that layer moduli can be accurately estimated by backcalculation using this method, with surface deflection calculated by the theory of elasticity for layer. This method was also applied to data of asphalt and concrete pavements, measured by the FWD. A new method was developed to backcalculate pavement layer moduli from pavement surface deflection, measured by a falling weight deflectometer (FWD), using genetic algorithms. It was found that layer moduli can be accurately estimated by backcalculation using this method, with surface deflection calculated by the theory of elasticity for layer structures as the input condition.
