摘要： A continuous asphalt mixture production plant based on double-horizontal-shaft forced mixing includes a cold aggregate bin, a continuous aggregate conveying and metering system, a drying drum, an aggregate elevator, a double-horizontal-shaft continuous mixing host, a continuous asphalt metering and conveying system, a continuous powder conveying and metering system and a finished product bin. The double-horizontal-shaft continuous mixing host includes a first double-horizontal-shaft mixing cylinder and a second double-horizontal-shaft mixing cylinder connected in series. The first double-horizontal-shaft mixing cylinder is provided with an aggregate inlet, an asphalt inlet, a powder inlet and a first discharging port, and the second double-horizontal-shaft mixing cylinder is provided with a mixture inlet and a second discharging port. The aggregate inlet, the asphalt inlet and the powder inlet are respectively connected with an outlet of the aggregate elevator, the continuous asphalt metering and conveying system and the continuous powder conveying and metering system correspondingly.
