In the room temperature regenerative ascon production apparatus according to the present embodiment, injecting iron oxide into the mixer 122 together with other materials (waste ascon, emulsifier for producing room temperature regenerative ascon, cement, etc.), the finally produced recycled ascon is brown. This is to have a color of red, yellow, and the like.

In general, asphalt pavement has a black color, but in parks, public offices, college roads, etc., ascones having a color of brown, red, yellow, etc. may be used for pavement.

By the way, the conventional recycled ascon manufacturing apparatus can only manufacture a recycled ascon for the road pavement of the achromatic color uniformly, so that it is not used for road pavement requiring brown, red, yellow, etc. There was an inconvenience in adding a separate color treatment to the recycled ascon.

However, the room temperature regenerative ascon production apparatus according to the present embodiment, since the iron oxide in the process of manufacturing the recycled ascon is mixed with other materials, it can be used for road pavement that requires colors such as brown, red, yellow, etc. Recycled ascon can be produced.

In the normal temperature regenerated ascon production apparatus according to the present embodiment, injecting the emulsified asphalt into the mixer 122 together with other materials (waste ascon, emulsifier for producing a normal temperature regenerated ascon, cement, etc.), the finally produced regenerated ascon is This is to have a black color suitable for road pavement.

In general, recycled ascons produced by recycling waste ascons generated from road excavation work have a gray color instead of black color of general road paving ascons. Therefore, when recycled ascons are used as road pavements, recycled ascons are used as road pavements. In order to have a suitable black color, there was the inconvenience of adding a separate color treatment to the finished recycled ascon.

However, the apparatus for manufacturing a room temperature regenerative ascon according to the present embodiment is mixed with other materials by adding an emulsified asphalt in the process of manufacturing the regenerative ascon, and thus the road pavement material is not added to the manufactured reclaimed ascon.

The emulsified asphalt storage bin 144 is an emulsified asphalt scale that emulsified asphalt conveyed from the emulsified asphalt storage tank 142 so that the emulsified asphalt scale bin 146 can measure the amount of emulsified asphalt to be fed into the mixer 122. It is temporarily held on the upper side of the bin 146.

On the other hand, the emulsion asphalt supply unit 140 includes an injection pump 148 provided on the second connecting pipe 147 to inject the emulsion asphalt, measured by the emulsion asphalt scale bin 146, into the mixer 122. .

Emulsified asphalt scale bin 146 is installed on the upper side of the mixer 122, since the emulsion asphalt has a certain fluidity, the emulsified asphalt in the emulsified asphalt scale bin 146 can be introduced into the mixer 122 by gravity. . However, when the emulsified asphalt is introduced into the mixer 122 by gravity alone, the emulsion asphalt has a constant viscosity, so that the feeding speed is slow, thereby increasing the tact time and decreasing the mixing performance in the mixer 122. There is a problem.

Accordingly, the emulsion asphalt supply unit 140 according to the present embodiment, by providing the injection pump 148 on the second connecting pipe 147 connecting the emulsion asphalt scale bin 146 and the mixer 122 to emulsify By injecting asphalt into the mixer 122 by spraying, the tact time is reduced, while the asphalted emulsion can be uniformly and smoothly mixed with other materials in the mixer 122, and thus the quality of the recycled ascone finally produced. Can improve. At this time, the nozzle 147a is provided at the end of the mixer 122 side of the second connection pipe 147 to facilitate the injection of the emulsion asphalt.
