Standard Test Method for Pavement Thickness by Magnetic Pulse Induction

Importancia y uso:

5.1 This test method covers the indirect measurement of the pavement thickness to provide a rapid, nondestructive result. The method is used to determine the compliance of asphalt or concrete pavement construction with the thickness specifications. The nondestructive thickness results for concrete pavements have shown excellent correlation (R² values of 99.7 %) with direct measurement of pavement thickness using AASHTO T 148 and Test Method C174/C174M.

5.2 Measurement results from MPI devices are unaffected by concrete or asphalt material composition, including the use of slag or other metallic aggregates, material temperature, or moisture content, thus allowing installers a quality control process that provides results that can be used in controlling the paving operation. In addition, quantitative results are produced to document as-built thicknesses.

5.3 Infrastructure owners use the same device to perform quality assurance activities and to accept installed facilities. Its accuracy and repeatability allow the reduction or elimination of coring requirements related to pavement thickness determination.
