Magnetic Imaging Tools Scanner (MIT Scan-2) Application in North America: Five Years After

MIT Scan-2 has been identified by the Federal Highway Administration (FHWA) as a practical, implementation-ready product that has the potential to improve quality of concrete pavements. Since MIT Scan-2 has been brought to the United States, evaluations of MIT Scan-2 have shown it to be a reliable tool for locating dowels with high accuracy for dowels inserted with cut dowel baskets or DBIs. The device was also found to be useful in qualitative measurement of uncut misaligned dowel baskets. The efficiency and ease of use of the device was also found to be robust for application to investigations that require large amounts of measurements in a wide range of environments. Numerous field evaluations of typical concrete pavement sections have shown that with proper construction practices, the dowels can be placed at relatively low misalignment levels. This technology may help the contractor ensure that the dowel bars are installed properly. However, this paper does not provide guidelines for dowel misalignment, as those will be developed in the NCHRP 10-69 study to be completed in 2008.
