Nondestructive Vibratory Testing of Airport Pavements. Volume II: Theoretical Study of the Dynamic Stiffness and Its Application to the Vibratory Nondestructive Method of Testing Pavements
A theoretical and experimental study of the dynamic load-deflection curves of pavements was conducted to determine the dependence of the measured dynamic stiffness values of a pavement on the type of vibrator that is used to make the measurements, and to correlate dynamic stiffness measurements obtained from different vibrators at the same pavement location. Experimental tests were conducted to verify the theoretical results. The dynamic load-deflection curves of pavements are found to be nonlinear, and a nonlinear vibration theory of pavements is developed to describe these curves. This study gives a method of determining the shear modulus and thickness of each pavement layer directly from the measured values of dynamic stiffness for a series of vibrator baseplate sizes. This method may be of practical value for nondestructively determining the subsurface structure of a pavement.
