A method of pavement evaluation and overlay design based on vibratory nondestructive testing and layered elastic theory was developed in Volume I of this report. Volume II validates this method by comparing it with the conventional methods of evaluation and overlay design for rigid and flexible pavements. Three airport sites were used for the validation. Results of the validation showed good agreement between allowable loads determined from the NDT-elastic theory method and the conventional standard method. However, there was poor agreement between overlay thickness requirements determined from the two methods. (Author).
