The nitrogen in the gas storage tank 6 is heated by the gas heater 5 in the prior art, and then the heated nitrogen is controlled and released through the gas control valve 4 in the prior art to be mixed with the asphalt. The asphalt keeps its temperature from dropping under the action of the heated nitrogen, protecting the asphalt from oxidation. Finally, it is sprayed into the kneading pot through the nozzle assembly.
