Mn/DOT's Non-Destructive Testing Program

A committee consisting of Minnesota Department of Transportation (Mn/DOT) Bridge, Pavement, and Geotechnical personnel was formed to examine the present and propose a future comprehensive Non-Destructive Testing (NDT) Program. The overall intent of their study was to define the scope of Mn/DOT's NDT program focusing on the Offices of Construction and Materials Engineering, Minnesota Road Research, and Bridge, with the intent of providing basis for future investment and use of NDT methods.

Several NDT devices are currently being used by the Department. They have a great potential for saving the Department time and money, and will enable the employees to perform their jobs better and more efficiently. Other NDT devices are still being investigated for their potential benefits to the Department, and have not been fully evaluated.

Though these devices may ultimately save time and money and improve performance, many are labor intensive. Staff approval must be obtained before making large financial or personnel commitments. It is recommended that each of the three areas have someone in charge of the evaluation of all new equipment and methods.
