摘要

Nondestructive testing (NDT) technology has made substantial progress in the last two decades. Currently, deflection-based, electromagnetic-based and seismic-based devices are available to the pavement community for rapid field data collection. Each of these technologies has strengths and weaknesses. However, when combined, they can provide a wealth of information not available when one method is used alone. In that context, combining the data from different methods falls under the broad category of joint inversion. In the Joint Inversion method (JIM), the raw or processed data from two or more NDT devices are input to an advanced backcalculation program. The objective of this software is to harvest the strength of different NDT methods and improve the parameters used in pavement design and evaluation. A new software package has been developed for this purpose. In this paper, the methodology used in developing JIM is provided along with a case study to demonstrate the application of this tool as compared with other traditional methods.
