Asphalt-based magnetic core, manufacturing method and pavement wireless charging system

The invention provides an asphalt-based magnetic core, a manufacturing method and a pavement wireless charging system. The asphalt-based magnetic core comprises an upper cylinder and a lower cylinder from top to bottom, the radius of the upper cylinder is the same as the inner diameter of a basic coil corresponding to the pitch-based magnetic core, and the height of the upper cylinder is the height of the inner core; the radius of the lower cylinder is the same as the outer diameter of a base coil corresponding to the pitch-based magnetic core, and the height of the lower cylinder is the thickness of the magnetic core. According to the pitch-based magnetic core, the radius of the upper cylinder and the radius of the lower cylinder are correspondingly set to be the same as the inner diameter and the outer diameter of the basic coil respectively, the coupling effect of the basic coil is improved, and the height of the inner core and the thickness of the magnetic core are determined according to the self-inducta
