Abstract
Disclosed is a plant of batch system for producing a composite paving material by using a bituminous waste pavement material, which comprises a heating means equipped with a new aggregate material introduction shoot and a bituminous waste material introduction shoot, the former shoot being connected to a new aggregate material supply passageway and the latter shoot being connected to a reproduction material supply passageway. The plant also comprises a ratio control section which is intended to compare with each other respective supplying indicated values of new and waste aggregate materials as measured by conveyor scales disposed with respect to their corresponding supply passageways, and thereafter proportionally control the value of the waste material relative to the value of the new material so that both the values may bear a predetermined mixing ratio. The ratio control section, thereafter, generates a command control signal to an inverter involved in the waste material supply passageway.
