BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a premixing apparatus for producing a recycled asbestos at room temperature and, more particularly, And to a premixing device for manufacturing a room temperature regenerated asphalt which can easily reduce the time required for processing.

The recycled asphalt at room temperature refers to recycled normal temperature asphalt concrete mixture for base layer using recycled aggregate for asphalt concrete, new aggregate, filler material, asphalt asphalt and recycled additives. Such room temperature recycled ascon is suitable for heating, recycled ascon base layer and whole ascon road pavement. It is environmentally friendly, low carbon green growth product and gradually becomes an eco-friendly product in order to purify the surrounding environment for human's abundant life.

Also, since the recycled asbestos produced at room temperature is produced at room temperature, unlike recycling, which is produced through heating, the manufacturing cost is reduced, and the application range of recycled non-recyclable products is expanding. The recycled asphalt can be recycled to minimize the environmental impact of the recycling, and the plant can mix recycled aggregate with recycled asphalt for room temperature mixing with the new aggregate at room temperature to produce a recycled asphalt mixture .

A method for manufacturing a room temperature regenerated ascon is generally carried out by a conveyor in a state where a new aggregate, a waste asbestos (hereinafter referred to as 'waste aggregate') and a filler are stored in a hopper, respectively. In addition, water, emulsified asphalt, and additives are stored in the storage tank, piped and transported to the agitator in a state where the water, emulsified asphalt, and additives are dosed in an appropriate amount. That is, in the above-described stirring apparatus, the liquid asphalt material consisting of water, emulsified asphalt and additives and the solid asphalt material composed of the new aggregate, the waste aggregate and the filler are agitated together.

Here, in the above-described stirring step, mutual stirring of water, emulsified asphalt and additives is incomplete, and the coating formed on the surface of coarse aggregate of solid asphalt material is formed inhomogeneously, There is a problem. In order to solve such a problem, there has been developed a technique for starting the pre-stirring process prior to the stirring fixation, but the improvement effect is insufficient, so that it is not easy to perform the optimized stirring process.

In addition, in the pre-stirring process, the workability and productivity of the whole room temperature recycled ascon is lowered due to the stirring process for the influent, and a loss in the production cost occurs when a defective process occurs in the pre-stirring process. There is a problem that an optimized pre-stirring process is required.

Therefore, there is a disadvantage in that it is not easy to effectively manufacture the room temperature regenerated ascon.
