BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pretreatment apparatus for ascon joints used for resurfacing asphalt roads, and more particularly, to an apparatus for pretreating joints of ascons formed as asphalt is repaved in a base layer of an asphalt road from which surface layers have been removed.

In general, to repave an asphalt road, the surface layer is removed to expose the substrate. Then, ascon is poured into one lane of the exposed substrate, and only one lane is first repacked, and the next lane is sequentially repacked.

However, in the case of repacking one by one, the ascon first packed is cured while cooling, and the ascon in the next repacked car is kept at a high temperature, so that the joining surfaces of the ascons facing each other are separated by the temperature difference. This is very weak.

As such, as the bonding force of the asphalt concrete surface is very weak, there is a problem that the bonded interface surface cracks or peels in a short time.

On the other hand, the device for spraying the flame and adhesive oil on the ascon joint surface in the vertical state has not been developed yet.

The present invention has been made in order to solve the above-mentioned conventional problems, and the asphalt concrete surface of one lane that is preferentially repaved on the base of the asphalt road from which the surface layer is removed, and the asphalt concrete surface is sequentially repaved. In order to provide a pre-treatment apparatus for ascon joints that not only heats resurfaced vertical ascon joint surfaces, but also applies an adhesive emulsion to pretreatment so that the ascon joint surfaces of the side lanes to be bonded with each other are strongly adhered to each other. This is the purpose.

It has an effect.

In addition, since the ascon spliced portion, which is preferentially repackaged, is pretreated by a torch and a nozzle, there is also an effect of improving the adhesive strength of the pretreated ascon spliced portion and the ascon spliced portion which is repacked in the sideways of the ascon spliced portion.

In addition, the height of the torch and the nozzle is controlled by the elevating unit, which not only has the effect of accurately spraying the flame and the adhesive with the ascon joint, but also the width of the torch and the nozzle by the horizontal moving unit. It also has the effect of spraying the emulsion more precisely on the ascon joint.

In addition, since the inclined guide plate intercepts the flame and the adhesive oil, not only can the injection efficiency of the flame and the adhesive oil be improved, but the inclination angle of the inclined guide plate is controlled by the turnbuckle, so that the injection efficiency of the flame and the adhesive oil is more reliably improved. There are also effects that can be made.

In addition, the opening and closing door-type emulsion inlet opening and closing the emulsion injection hole of the emulsion tank while rotating uniaxially can not only easily inject the adhesive oil, but also has the effect of sealing the emulsion injection hole in the airtight state.

In addition, the traveling cart can be easily driven by using the towing vehicle, and the towing vehicle and the traveling cart can be easily connected by connecting the towing vehicle to the traveling cart using a male and female coupler composed of a king pin and a pin ball. At the same time, there is an effect that can be easily separated as needed.
