step two, a feeding process, namely pumping liquid asphalt to an inner core of the main shaft (341) by the asphalt melting machine (1), simultaneously conveying powder to the powder feeding assembly (32) by the powder conveyor (2), and discontinuously feeding the outer core of the main shaft (341) by the powder feeding assembly (32);
step three, a slitting process, namely forming a curtain-shaped asphalt surface after the liquid asphalt flows through an asphalt spraying piece (342), and slitting the asphalt surface into granular liquid drops by a separating unit (343);
step four, proportioning and mixing, wherein a powder spraying part (344) receives granular asphalt droplets, powder is sprayed onto the surface from the powder spraying part (344), and the powder is mixed with the asphalt droplets;
and step five, a stirring procedure, namely after the proportioning and mixing are finished, the asphalt and the powder fall into a stirring barrel (31), and a stirring paddle at the bottom of the main shaft (341) is used for stirring the asphalt.
