Description: Technical report
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 a pavement system. The modulus values are used to determine the structural capac~ty 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.
