The ASTM E3013/E3013M-17 standard is titled "Standard Test Method for Evaluating Concrete Pavement Dowel Bar Alignment Using Magnetic Pulse Induction." This standard describes a nondestructive testing method for assessing the alignment of dowel bars in concrete pavements. Dowel bars are used in the joints of concrete pavements to transfer loads between slabs and prevent damage.

The standard highlights the importance of examining dowel bars to ensure efficient load transfer and prevent pavement damage. Magnetic pulse induction (MPI) is used to examine dowel bars by inducing a weak-pulsed magnetic field that detects the presence of metal objects. This method provides reliable quantitative results that are repeatable with calibrated MPI devices.

The standard also emphasizes the use of MPI as a quality control process for installers to document correct dowel bar installation in new pavements. It enables owners to perform quality assurance activities and accept facilities from contractors. The standard covers the equipment, field procedures, and interpretation methods necessary for the assessment. MPI equipment includes systems scanning devices, orientation systems, field data collection devices, and analysis software.

The field procedures describe the steps to collect reliable and accurate results, emphasizing the absence of any metal items except for the dowel bars near the joints being tested. The interpretation methods provide guidance on analyzing the collected data, addressing interferences and anomalies, and producing accurate results for the dowel bar positions. The standard also specifies minimum report content to ensure meaningful test information is provided.
