Dowel alignment can be measured efficiently and accurately using MIT Scan-2, a state-of-the-art nondestructive testing device for measuring and recording the position and alignment of dowel bars (FHWA 2005; Yu and Khazanovich 2005). The device is easy to use, the dowel alignment can be checked within a few hours of concrete placement, and the results can be printed using the onboard printer immediately after scanning. Up to 400 or more joints can be tested in an 8-hr workday using MIT Scan-2.
