NONDESTRUCTIVE AIRFIELD RIGID PAVEMENT EVALUATION

Abstract

A nondestructive evaluation procedure is presented that has been developed for a variety of NDT equipment. The methodology is based on layered elastic theory and uses a performance model developed previously for airport type loadings. A study was conducted at MacDill Air Force Base to compare evaluation methodologies being used on airport pavements. Data from six different NDT devices is used to evaluate two rigid pavements. Results are presented to illustrate the applicability of this evaluation procedure for those devices. Comparisons of allowable aircraft loads determined from NDT and destructive evaluation procedures are presented.
