The utility model discloses a whole batching process except that pitch is squeezed into the metering tank and is used the viscous crude pump, the transport of other materials between the jar does not in fact rely on the pump to accomplish. The viscosity of the pure asphalt is smaller than that of the modified asphalt and the modified asphalt mixture added with the filler, so that the viscous asphalt has little abrasion to the viscous oil pump.

The whole tower structure of the batching system is designed to be in a semi-closed state, namely three sides are closed, one side is open, and the position of the batching system is arranged beside a production line oiling pool. Therefore, a large amount of smoke emitted by the modified asphalt material in the oil coating pool in the coil forming process is sucked away through the smoke hood above the oil coating pool, and the smoke overflowing the smoke hood is easily discharged along the open surface of the tower structure. Therefore, the three-dimensional tower type structure arrangement is beneficial to improving the working environment of the whole coiled material production workshop. The materials for modified asphalt can be directly stacked on the 3 rd layer of the tower structure when the raw materials enter a factory, the materials and the tank are separated by a wall body, and a modifier feeding system is adopted during material mixing.
