Description
1.1 This test method covers the equipment, field procedures, and interpretation methods for the assessment of Portland Cement Concrete Pavement dowel bar alignment using Magnetic Pulse Induction (MPI), also referred to as magnetic imaging tomography or eddy current tomography. Magnetic Pulse Induction (MPI) devices induce a weak pulsed magnetic field that causes the induction of eddy currents in metal objects disturbing the field. When metal (dowel bar) enters into the field an electrical signal is produced and processed through algorithms to detect and produce quantitative values for the depth, alignment and side shift locations of each dowel and tie bar present in the pavement joint.
