Development of a Reliability-Based Method for Evaluating a Pavement Feature.

Abstract

Nondestructive testing (NDT) is used to evaluate the structural capacity of in-place pavements. NDT is accomplished with the use of a falling weight deflectometer (FWD). The data obtained with the FWD are used to determine the modulus value of the layers in the pavement system. The modulus values are used to determine the structural capacity of the pavements in terms of allowable load, allowable passes, and overlay thickness requirements. Because NDT provides a means of rapidly testing a pavement, many tests are conducted on a pavement feature. Currently, the method for evaluating a pavement feature uses the mean NDT. This study was conducted to investigate the effect of using the mean NDT. The results of this investigation provide a statistical approach for evaluating a pavement feature using NDT procedures at a user-defined level of reliability.
