Sensing Mechanism of Magnetic Asphalt Road Materials

This paper studys the perceptual mechanism of magnetic asphalt road materials. Through the analysis of the spatial distribution of three-dimensional static magnetic fields of rectangular permanent magnets, the characteristic quantities that can reflect the magnetic field distribution rules are found, combined with the magnetic field distribution rules of rectangular permanent magnets, and the magnetic asphalt samples are The magnetic field distribution is studied to determine the characteristic parameter values that can reflect the magnetic field distribution of magnetic asphalt samples, and then the influence of magnetic asphalt road pavement sample mass fraction and measurement height on the magnetic induction intensity By is obtained, which provides guidance for the design of magnetic asphalt roads.
