Abstract:

Timely detection of misplaced steel would provide feedback needed to correct the construction process. To address this need, KDOT developed a field instrument capable of non-destructively assessing the placement (depth and orientation) accuracy of reinforcing steel in PCC pavement using magnetic tomography technology with real time feedback. Several iterations of prototype carts were developed. The final prototype cart developed and constructed used two sensors to determine the steel location.
