The present invention relates to a method for manufacturing a pelletized anti-stripping agent composition for warm-mix asphalt that can be directly put into an asphalt plant, is capable of improving moisture resistance for dealing with stripping and potholes, and having a warm-mix function. The present invention includes: a liquid emulsion product manufacturing step in which a liquid emulsion product is produced by the mixing of wax, vegetable oil, mineral oil, surfactant, and water at a predetermined ratio in a liquid emulsion product manufacturing unit; a slaked lime mixing step in which the liquid emulsion product manufactured in the liquid emulsion product manufacturing unit is transferred to a slaked lime mixing unit and a slaked lime mixture is produced by the mixing of the liquid emulsion product with slaked lime at a predetermined ratio; an extrusion step in which the slaked lime mixture produced in the slaked lime mixing unit is transferred to an extrusion unit and a strand is produced by means of extrusion into a pellet form; and a strand cutting step in which the strand produced in the extrusion unit is transferred to a strand cutting unit and cutting is performed for pelletized anti-stripping agent production.
