BACKCALCULATION OF PAVEMENT LAYERS PROPERTIES
This paper was prepared for the symposium as a state-of-the-art paper. The paper summarizes the history and present use of nondestructive testing (NDT) and speculates on future developments and uses of NDT in backcalculating pavement layer properties. The paper concentrates on the backcalculation of the elastic stiffness of pavement layers. Measurement methods include a variety of methods of applying loads to the pavement and a number of sensors of the pavement response. Loading methods include static or slowly moving loads, vibration, near field impulse, and wave propagation which applies to far field measurements. A fundamental distinction is drawn between near field impulse loads which closely simulate traffic loads and far field impulse loads, the results of which must be corrected substantially to provide realistic pavement layer moduli.
