FIG. 13 is a perspective view showing an embodiment of the installation heater, and shows a configuration of the installation heater equipped with an auxiliary road heater at the rear so as to install the recycled ascon on the pavement and reheat it.

That is, as shown in FIG. 1, the present invention efficiently and quickly reproduces an aging portion generated on the pavement 10 to induce immediate opening of the pavement 10, and also enables safe driving of the vehicle. It is a configuration to ensure that.

To this end, the present invention first constructs a road heating step (1) to impart fluidity by heating an aging portion of the pavement (10) in which aging occurs.

This is because the asphalt concrete constituting the pavement 10 may be broken when the aging portion of the pavement 10 is cut in a state in which there is no fluidity, and thus, the aging phenomenon is generated through the road heating step 1. When the road 10 is heated to impart fluidity, the asphalt concrete can be prevented from being broken during the cutting of the aging portion.

In order to regenerate the pavement 10 as described above, the road heating step 1 is first performed. In the present invention, as shown in FIG. 2, the road heater 11 having the heating means 15 is provided and paved. The aging part of the road 10 is heated to impart fluidity.

As shown in FIGS. 2 to 7, the road heater 11 is installed on the front side of the power vehicle 12 moving along the pavement 10, and the road surface in which the aging phenomenon occurs along the power vehicle 12. The aged portion of (10) is heated.

The power vehicle 12 is moved along the pavement 10 in a state where a generator 13 for generating electric power is mounted, and the road heater 11 is installed on the front of the power vehicle 12. It is shown connected to the generator (13).

At this time, the road heater 11 is installed to move up and down on the front of the power vehicle 12 to lower and heat during the regeneration operation of the pavement 10, and to rise after the regeneration operation of the power vehicle 12 It is desirable to allow safe movement.

In addition, the road heater 11 is mounted on the front and rear wheels 114, respectively, when the road heater 11 is lowered when heating the aging portion of the pavement 10 by using the wheel 114 It can be heated while moving smoothly.

Inside the road heater 11 is a heating means 15 for imparting fluidity by heating the road surface of the pavement 10 is built, the heating means 15 in the embodiment of the present invention at least one magnetron 150 is mounted to heat the aging portion of the pavement 10 with the electromagnetic waves emitted from the magnetron 150.

That is, the road heater 11 applies the electric power generated from the generator 13 to the plurality of magnetrons 150 in a state in which it is installed in the front of the power vehicle 12 by the height cylinder 14 and the magnetrons 150. It is to heat the road surface of the pavement 10 with the electromagnetic waves emitted from.

As shown in FIG. 3 for mounting the magnetron 150, the heater body 110 having an installation space 111 therein is coupled to the guide member 112 for mounting the magnetron 150, the guide At least one magnetron 150 is mounted to the member 112.

As shown in FIG. 4, the magnetron 150 has a positive electrode as the anode 151 and a cathode 152 and a grid (not shown) are arranged in the axial direction. A plurality of hollows 153 are provided in a circular shape in which silver is provided, and the cathode 152 is provided in the form of a shaft to be used by combining the cathode 152 with the center of the anode 151.

Accordingly, when the magnetic field is applied in the axial direction of the cathode 152, electrons protruding in the radial direction from the cathode 152 are attracted to the anode 151 and are subjected to a right angle force in the advancing direction by the magnetic field.

In other words, the electrons move in a spiral motion. When the intensity of the magnetic field is increased, the amount of the electrons is increased, and the electrons are rotated many times before reaching the anode 151.

When the strength of the magnetic field reaches a certain limit (critical magnetic flux density), electrons hardly reach the anode 151.

As a result, a rotating electromagnetic pole is generated around the cathode 152 and a microwave as an induced current is generated in the hollow portion 153 of the anode 151 to heat the road surface of the pavement 10 at the wavelength of the microwave. .

Microwave is a generic term for electromagnetic waves in the frequency region between 300 MHz and 30 Hz, and in the present invention, especially 2,450 MHz, the electromagnetic wave of 5 Hz or less is irradiated onto the pavement 10 to vibrate and heat the asphalt molecules contained therein. do.

That is, microwaves, which are electromagnetic waves emitted by the magnetron 150, vibrate by irradiating asphalt molecules on the pavement 10, thereby rapidly heating the pavement 10 to impart fluidity.

Here, the side of the guide member 112 on which the magnetron 150 is mounted so that the electromagnetic waves of the magnetron 150 that performs this role intensively heat only the pavement 10 and are not irradiated to the worker performing the same. Inside the shielding layer 113 is formed through the electromagnetic wave blocking element.

This is because the electromagnetic wave emitted from the magnetron 150 may seriously threaten health when irradiated to the worker unexpectedly, the shielding layer 113 through the electromagnetic shielding element inside the side portion of the guide member 112. If this is formed will be shielded so that the electromagnetic wave is irradiated only in the downward direction so as not to be irradiated outside the road surface of the pavement (10).

Although there are various kinds of electromagnetic wave blocking elements for forming the shielding layer 113, in the embodiment of the present invention, the shielding layer 113 is shielded from reflecting or absorbing and passing electromagnetic waves emitted from the magnetron 150.

The conductor is a material that conducts electricity, and when electromagnetic waves are radiated from the magnetron 150, the conductor reflects or absorbs the electromagnetic waves and serves to shield them from passing.

Representative of the conductor is composed of copper, aluminum, gold, silver, iron, carbon, and the like, it is selected and used.

In particular, the most suitable may be copper, which is low in cost and excellent in electromagnetic shielding effect.

In addition, the electromagnetic wave blocking element made of the conductor of the above configuration may be formed in a single shape to be attached to the inside of the side of the guide member 112, but more preferably, finely mixed the conductor, and then mixed with the guide member ( It is preferable to form the shielding layer 113 by coating the inner side of the side 112.

That is, when the fine powder of copper, aluminum, gold, silver, iron, carbon, and the like to be mixed at 30 to 80% by weight and then coating the inside of the side of the guide member 112 to form a shielding layer 113 magnetron ( It is possible to more effectively reflect or absorb the electromagnetic wave emitted from 150) to shield.

Thus, as the shielding layer 113 is formed inside the side portion of the guide member 112 on which the magnetron 150 is mounted through the electromagnetic wave blocking element, electromagnetic waves emitted from the magnetron 150 are effectively shielded and paved roads ( 10) It is possible to block the investigation of the worker who plays the regeneration in advance.

On the other hand, another embodiment of the heating means 15 is built in the road heater 11 to heat the road surface of the pavement 10, as shown in Figure 5, a pair of heat generating terminals 156 to generate heat by an external power source ) Is coupled to both ends of the ceramic protective tube 155 filled with the insulating material 157 therein, and the heating element 158 interconnecting the heating terminals 156 is accommodated inside the ceramic protective tube 155. .

The ceramic protective tube 155 having the above configuration is embedded in the road heater 11 through the fixed bracket 159.

Therefore, when power is supplied from the generator 13 of the power vehicle 12 to the heat generating terminal 156, the heat generating element 158 connecting the heat generating terminal 156 generates heat and generates heat of the heat generating element 158. The silver is transferred to the ceramic protective tube 155 through the insulating material 157 and finally the ceramic protective tube 155 generates heat to emit infrared rays.

Here, the infrared radiation emitted from the ceramic protective tube 155 is a kind of energy wave, and refers to light having a wavelength band of 0.76 μm to 1,000 mm.

Depending on the wavelength, 0.76 ~ 1.5㎛ is called near infrared, 1.5 ~ 5.6㎛ is called mid-infrared and 5.6 ~ 1,000㎜ is called far-infrared. In particular, far-infrared rays of 6 ~ 14㎛ wavelength are the most suitable for heating. It has a strong heat action.

Such infrared radiation is radiant heat energy, which generates heat by reaching heat to be heated without an intermediate heat transfer medium, and thus has high thermal efficiency and direct heating without convection (air). Since it coincides with the wavelength of the material, it promotes molecular motion due to resonance (resonance) phenomenon, so that the radiant energy is easily absorbed and the heating time is reduced.

That is, the infrared rays are radiated from the ceramic protective tube 155 and then irradiated to the aging part of the pavement 10 and heated to a predetermined temperature, thereby providing fluidity to the aging part of the pavement.

Another embodiment of the road heater 11 using the radiant heat energy is a configuration using a ceramic heat sink 160, the configuration is shown in Figures 6 to 7, the gas supply device 161 and this gas A transfer hose 162 connected to the supply device 161 to transfer the discharged gas, an on / off valve 163 mounted on the transfer hose 162 to control the transfer of gas, and the transfer hose 162. A gas combustion device 164 connected to the gas combustion device 164 and a ceramic embedded in the road heater 11 mounted on one surface of the gas combustion device 164 to radiate infrared rays together with heat during combustion of the gas. It is made of a heat sink (160).

The gas supply device 161 may be used by mounting a known gas cylinder on the power vehicle 12, and in addition, it may be known that the gas supply device 161 may be directly supplied with a gas from an LPG gas supply source.

Therefore, when the on-off valve 163 is opened while the ceramic heat dissipation plate 160 having the above structure is embedded in the road heater 11, the gas discharged from the gas supply device 161 passes through the transfer hose 162. Heat transferred to the combustion device 164 and burned, and heat generated as gas is burned is transferred to the ceramic heat sink 160, and the ceramic heat sink 160 finally radiates infrared rays together with the heat to the pavement 10. The aging part of) is heated to impart fluidity.

As such, the magnetron 150, the ceramic protective tube 155, and the ceramic heat dissipation plate 160, which are heating means 15, which impart fluidity by heating the aging part of the pavement 10, are embedded in the road heater 11, respectively. Although used in, the magnetron 150, the ceramic protective tube 155, and the ceramic heat sink 160 may be used in a state in which both the road heater 11 is built.

The cutting step (2) is a step for cutting the aging part of the pavement (10) to which fluidity is imparted by the road heater (11) of the above configuration, and there are various examples for performing the cutting step (2). However, in the exemplary embodiment of the present invention, the non-powered rotating drum 21 is mounted on the rear of the power vehicle 12 to perform the cutting step 2 of cutting the aging part of the pavement 10.

That is, as shown in FIG. 8, the non-powered rotating drum 21 is mounted to the rear of the power vehicle 12 so that the height can be adjusted through the height adjustment cylinder 23 so that the pavement road during the movement of the power vehicle 12 ( Will rotate along 10).

Then, a plurality of cutting edges 22 are detachably mounted on the outer circumferential surface of the non-powered rotating drum 21 rotating along the pavement 10 to cut the aging portion of the pavement 10 to which fluidity is given. .

In this case, the cutting blade 22 is detachably coupled to the non-powered rotating drum 21 because wear may proceed quickly due to the characteristics of the cutting blade 22 when the cutting machine 20 is used for a long time. In order to perform a smooth cutting step 2 by separating the worn and damaged cutting edge 22 from the non-powered rotating drum 21 and replacing it with a new cutting edge 22.

As the plurality of cutting edges 22 are detachably coupled to the outer circumferential surface of the non-powered rotating drum 21 as described above, the aging portion of the pavement 10 may be efficiently cut through the cutting edges 22. It will be possible.

In addition, although the cutting edge 22 is shown in a rectangular shape in the present invention, this is one example, it can be molded and used in various forms such as circular, polygonal, rectangular, bite type according to the needs of those skilled in the art, pavement road According to the aging state of (10) it is mounted at right angle or 60 ° ~ 80 ° angle toward the ground.

Therefore, when the power vehicle 12 moves along the aging part of the pavement 10 with the cutting machine 20 configured as described above mounted at the rear of the power vehicle 12, the non-powered rotating drum 21 is packed. It is to be cut through the cutting blade 22 while being in close contact with the road (10).

The non-powered rotating drum 21 is lowered or raised through the height adjusting cylinder 23 according to the aging state of the pavement 10 where the aging phenomenon occurs to cut the aging part of the pavement 10.

As shown in FIGS. 9 to 10, the main body frame 25 having the front opening is opened and the discharge port 26 formed thereon is shown in another embodiment of the cutting machine 20. It is installed at the rear, and the power rotating drum 28 driven by the driving force of the power source 27 is mounted inside the main body frame 25, and the disk-shaped cutting blade (circle around the power rotating drum 28) 29 is coupled to cut the aging portion of the pavement 10 when the power vehicle 12 moves.

The power source 27 for driving the power rotating drum 28 is driven by an external power source to generate power, and is sufficient to cut the aging portion of the pavement 10 using the disc-shaped cutting blade 29. It generates power.

To this end, the embodiment of the present invention shows that a known drive motor is used as the power source 27, which is mounted on the side of the main body frame 25 in the state connected to the power rotating drum 28, the outside The power rotating drum 28 is driven when power is supplied.

Here, as an external power source for driving the power source 27, the generator 13 of the power vehicle 12 is used in connection, or, if necessary, an electric line drawn from the power source 27 is used as a separate battery (not shown). ) Can be used directly.

That is, when the power vehicle 12 is in operation, it is possible to drive by connecting the electric line of the power source 27 to the generator 13 mounted on the power vehicle 12, when this generator 13 is not available There is a separate battery connected to the power source 27 to be driven.

Therefore, when the power vehicle 12 moves along the aging part of the pavement 10 with the cutting machine 20 configured as described above mounted on the rear of the power vehicle 12, the power rotating drum 28 The rotating disk cutting blade 29 is to cut the aging portion of the pavement (10).

The waste ascon cut through the disc-shaped cutting blade 29 is discharged to the outside through the upper outlet 26 after hitting the inner rear of the main body frame 25, and is discharged to the open front to prevent the cutting operation. The partition 25a is protruded from the main body frame 25 so as not to be noticed.

In addition, the disc-shaped cutting edge 29 for cutting the aging portion on the pavement 10 has a slope of 15 ° to 80 ° toward the ground and are coupled to face each other to effectively aging the aging portion of the pavement (10) At the same time it is possible to cut the waste ascon cut so that it can move naturally toward the outlet (26).

The hourly working amount of the cutting step 2 through the cutting machine 20 configured as described above is preferably 250 m 2 / hr ~ 294 m 2 / hr which can maximize the cutting efficiency of the cutting machine 20, which is 250 If less than ㎡ / hr may take a long time according to the regeneration of the pavement, the cutting efficiency may be reduced when the amount of work per hour 294 ㎡ / hr or more, in the present invention to maintain between 250 ㎡ / hr ~ 294 ㎡ / hr Will be

The flattening step (3) is to flatten the aging part of the pavement (10) through the cutting step (2) through the cutting machine 20 to make the regeneration process smoothly and efficiently through the recycle ascon at the same time Through 20, it is constructed to completely remove the aging portion of the pavement (10) that has not been removed.

In the present invention for the flat plate step (3), as shown in Figure 11, there is provided a flat blade 30 having a hook piece 31, the flat blade 30 is the automation and regeneration of the present invention regeneration method As shown in FIG. 8 to increase the efficiency, in the case of the non-powered rotating drum 21, the pavement road 10 is not cut in the cutting step 2 through the cutting machine 20 by being coupled to the height adjusting cylinder 23. It is to remove the aging part of.

A plurality of fixing holes 32 are drilled in the hook piece 31 for mounting the flat blade 30 to the rear of the cutting machine 20 to adjust the mounting position according to the cutting depth of the pavement 10. .

Therefore, the aging part of the pavement 10 is flattened by the construction of the flattening step 3 using the plate blade 30 having such a configuration, thereby completely removing the aging part of the pavement 10. In addition, through the flat blade 30 will be able to enjoy the side effect of smoothly supplying the waste ascon cut by the cutting machine 20 to the stirrer 40 to be described later.

On the other hand, the stirring step (4) is a step for stirring and regenerating the aged waste ascon cut on the pavement (10) through the cutting machine 20, through the stirring step (4) without the addition of a separate new aggregate The aging portion of the pavement 10 is to be recycled.

In order to perform the stirring step (4) for regeneration of aging waste ascon, the present invention provides a stirrer (40), the configuration of the stirrer (40), as shown in Figure 12, the waste ascon input A 41 is mounted to be opened and closed at an upper portion thereof, and a mixer 42 for mixing the supplied waste ascon is rotatably installed therein, and a heater 43 for heating the mixed waste ascon is mounted therein. It is shown that the discharge conveyor 44 for discharging the waste ascon stirred and regenerated while passing through 43 is installed on the side.

In the embodiment of the mixer 42 which is rotatably installed in the stirrer 40 to mix the waste ascon, the present invention shows that a pair of rotating screws are rotatably installed in the stirrer 40.

That is, the mixer 42 is composed of a rotating screw having three wings, as shown in Figure 12 is installed rotatably inside the stirrer 40, the rotational speed is dependent on the input amount of the waste ascon, Maintain 10rpm ~ 30rpm, and wings should not exceed 200mm in length.

In addition, although the number of the blades of the rotating screw is shown as three in the drawings of the present invention, it will be apparent in advance that it can be mounted by varying the number of wings mounted on the rotating screw, if necessary.

At this time, the bottom of the stirrer 40 is preferably manufactured in a semi-circular shape so that the waste ascon does not accumulate on the bottom of the stirrer 40 outside the rotation range of the mixer 42 when stirring the waste ascon through the mixer 42. Do.

Therefore, when the waste ascon cut in the aging portion of the pavement 10 is introduced into the stirrer 40, aggregates of the waste ascon which were separated by stirring by the rotation of the mixer 42 are mixed with each other.

When waste ascon is supplied in a large amount at one time in the stirrer 40 having such a configuration, the operation of the mixer 42 may be overwhelmed. In the present invention, a separate supply conveyor 45 is provided to the stirrer 40. ) And then installed between the cutting machine 20 is shown to supply through it.

That is, when the supply conveyor 45 is installed between the stirrer 40 and the cutting machine 20, the waste ascon cut by the cutting machine 20 is supplied and fed into the stirrer 40 to the mixer 42. The waste ascon can be stirred and regenerated as long as it does not overload the operation.

As shown in FIG. 8, when the non-powered rotating drum 21 is used as the cutting machine 20, the supply conveyor 45 is driven by mounting a separate power source 27 at the rear of the power vehicle 12. When the power rotating drum 28 is used as the cutting machine 20, the supply conveyor 45 is driven by using the power source 27 mounted on the power rotating drum 28.

This power source 27 and the supply conveyor 45 is shown to be connected via a belt or chain.

At this time, in the process of performing the stirring step (4) to add the waste ascon cut from the pavement 10 to the stirrer 40, stirring, regeneration to perform the additive input step (5) of the waste ascon Properties will be restored to quality similar to new packaging.

This is because the particles of waste ascon cut from the existing road are smaller than the particles of aggregates produced and constructed for the first time, and some of them become smaller due to crushing. If it is installed and regenerated at (10), the quality and strength maintenance may be significantly lowered, so that the additive is added and stirred.

Such additives include (AP) -3, AP-5, RC-1-4, MC-1-4, RS (C)- 1-4), thermoplastic vinyl powder, thermoplastic resin powder, portland cement, amide polymer asphalt, rubber modified asphalt, latex rubber powder, waste tire rubber powder, gilsonite, natural hydrocarbon resin, cellulose fiber, polymer modified asphalt of synthetic rubber At least one or more of sand, silica, crushed gravel, steel slag, glass beads, and glass fibers are included.

Among these asphalt series (AP-3, AP-5, RC-1-4, MC-1-4, RS-1) 4) is classified asphalt cement according to the penetration, AP-3 is the penetration of 85 ~ 100, AP (AP) -5 refers to the penetration of 60 ~ 70.

The RC (RC) -1-4, MC (MC) -1-4, RS (C) -1-4 is made by mixing petroleum solvent with asphalt of 60 to 120 intrusion degree and made soft According to the viscosity, RC (rap) means rapid curing (MC), MC (MC) means medium curing, (SC) means slow curing (slow curing).

The thermoplastic resin used in the thermoplastic resin powder may be any one or a mixture of vinyl acetate, vinyl acetate, methyl metall, polyethylene, nylon, polyacetal resin, vinyl chloride, polystyrene, acrylic resin, and celluloid. Done.

As the synthetic rubber, styrene butadien rubber (SBR) and polychloroprene rubber (CR) are typically used.Stone powder, silica sand, sand, crushed gravel, steel slag, glass beads, glass fiber Increases the friction of the pavement 10 to shorten the braking distance of the vehicle.

However, it is noted that the additives listed above are merely examples, and the type of the additives is not necessarily limited thereto, and may be changed according to construction and construction conditions.

Therefore, these additives are introduced into the stirrer 40 during the stirring and regeneration of the waste ascon and are stirred together with the waste ascon via the mixer 42, so that the quality and strength thereof are almost the same as those originally produced at the production plant. It is sustainable.

On the other hand, in the process of mixing the waste ascon through the stirrer 40, the heater 43 is built in the stirrer 40 so that the mixing of the waste ascon and the additive can be made more smoothly.

The auxiliary road heater 70 is the auxiliary heater in the same configuration as the road heater 11 shown in Figure 3 to provide fluidity by heating the aging portion of the pavement 10 in a state mounted in front of the power vehicle 12 As the road heater 70 is mounted to the rear of the installation heater 60, the additional heating step 7 for reheating the recycled ascon installed on the pavement 10 in the field gives fluidity.

In addition, a separate heating device 63 that radiates electromagnetic waves or radiant heat energy is installed inside the collecting part 61 provided on the installation heater 60 so that the recycled ascon is not lowered during transfer. Good to do.

Therefore, the road laying step 6 of laying the regenerated and recycled recycled ascon on the pavement 10 where the aging part is cut while going through the stirring step 4 through the laying heater 60 of the above configuration is performed. The lowering of the temperature of the recycled ascon during the laying process can be compensated by the heating device 63, and the reclaimed ascon which has been laid is endowed with fluidity through the additional heating step 7 using the auxiliary road heater 70. Will be.

The recycled ascon, which is reheated by the auxiliary road heater 70 and is provided with fluidity, is compacted and cured while undergoing the road compaction step 8 through the compactor 80.

The road compaction step 8 through the compactor 80 first vibrates and presses through the macadam rollers, secondly to clean up the road surface using a tire roller, and finally to finish the pavement using a tandem roller. The rebuilding construction of the road 10 is to be completed.

According to the configuration of the present invention as described above, by heating the road surface on the pavement road in which the aging phenomenon occurs by providing a road heater, or by reheating the recycled ascon laid on the pavement coating to impart fluidity, thereby cutting the aging part Ascon aggregate is prevented from being broken in the process, and curing through the compactor can be made smoothly.

In addition, by providing a stirrer, the waste ascon cut on the road is agitated in the field, and the additive is added and regenerated, thereby regenerating the aging part of the pavement using recycled ascon instead of adding new aggregate or a separate new ascon. It becomes possible.

Therefore, it is a very useful invention, such as minimizing the construction time for quickly and accurately regenerating the aging part of the pavement road, thereby preventing the occurrence of traffic jams.
