The present invention generally relates to an additive package for warm-mix asphalt formulations for the pavement of road surfaces, said additive package comprising a) surfactant component, and b) an asphalt rheology modifying component, wherein said asphalt rheology modifying component comprises at least one of a i) a wax component and ii) a resin component. The rising position or the falling position of at least one pulse signal indicative of the origin is determined by the detection signals of the two or more mark portions for producing the origin signal by the origin detecting system. The material to be cultivated can be caused to undergo expansion or contraction by applying and relieving the tensile stress, thereby applying a physical stimulation necessary for the proliferation to the material to be cultivated.
