A method for laying a magnetic asphalt road surface for assisted driving according to any one of claims 1 to 7, characterised in that, The method comprises the following steps: S1: in the process of laying the magnetic asphalt pavement, first open the vertical telescopic arm (121), the output shaft of the vertical telescopic arm (121) pushes the plane plate (122) to slide upward in the storage bucket (12), the plane plate (122) pushes the magnetic encoding unit to move to the top of the storage bucket (12), then start the horizontal telescopic arm (131), the output shaft of the horizontal telescopic arm (131) pushes the push plate (132) to move in the horizontal direction according to a certain frequency, pushes the uppermost magnetic encoding unit in the storage bucket (12) into the top of the cylindrical barrel (112), the magnetic encoding unit is located on the multiple horizontal state annular support plate (111), the annular support plate (111) carries the magnetic encoding unit downward transportation; S2: when the annular support plate (111) moves to the lowermost of the cylindrical barrel (112), the support bar (113) will rotate around the annular support plate (111), the magnetic encoding unit also continues to move downward with the increasing angle of the support bar (113) rotation until falls to the ground, while the annular support plate (111) drives the support bar (113) to move upward to the uppermost end of the cylindrical barrel (112), the support bar (113) also restores the horizontal position to wait for the transportation of the next magnetic encoding unit, at this time the whole magnetic encoding unit laying device completes a job; S3: at the same time, start the vehicle body (a), the vehicle body (a) drives the rolling wheel (51) to roll on the ground, the rolling wheel (51) drives the rotating shaft (52) at its axis to rotate, the rotating shaft (52) drives the stirring paddle one (23), the stirring paddle two (33), the stirring paddle three (221) and the stirring paddle four (321) to rotate at the same time through the multiple transmission belts (6); S4: then the magnetic asphalt concrete in the storage box one (21) is fully stirred and discharged into the discharge pipe one (22), after the discharge port (222) completely passes through the magnetic encoding unit, the gate of the discharge port (222) is automatically opened, the magnetic asphalt concrete in the discharge pipe one (22) is completely discharged through the discharge port (222), and the asphalt concrete strip with magnetism is laid between the adjacent two magnetic encoding units; S5: then the ordinary asphalt concrete in the storage box two (31) is discharged through the discharge pipe two (32), and the ordinary asphalt concrete is laid on the magnetic encoding unit and the magnetic asphalt mixture pavement, and the laying of the magnetic asphalt pavement is completed.
