Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a moving asphalt mixture manufacturing apparatus, an asphalt mixture manufacturing method, a moving asphalt mixture manufacturing apparatus, a moving asphalt mixture manufacturing apparatus,

The present invention relates to a mobile asphalt mixture production apparatus capable of manufacturing an asphalt mixture while heating the road surface so that the asphalt adhesion force and the compaction density can be improved, and the prepared asphalt mixture can be installed and compaction on a heated road surface, Asphalt mixture, a method of manufacturing the same, and a construction method using the apparatus for manufacturing a mobile asphalt mixture.

Generally, road pavement is packed with cement or asphalt. When it is necessary to open the road quickly, asphalt pavement method is mainly applied.

Asphalt pavement is more durable than cement pavement, plastic deformation is more likely to occur during the summer season, and there is a high possibility of road surface damage such as potholes during rainfall.

In addition, if an asphalt mixture is installed on a cold road surface (crushed stone layer or asphalt layer) during the winter season, the temperature of the installed asphalt mixture will drop sharply, resulting in poor compaction, leading to poor packaging.

Therefore, except when it is absolutely necessary, it is general not to use the asphalt mixture for the pavement construction at the temperature of 5 ℃ or less in the winter season.

On the other hand, the asphalt pavement is mainly made by using a fixed asphalt manufacturing facility. After heating the road surface and cutting the heated part, the cut surface is cut by mixing the cut material with the new asbestos or new aggregate, asphalt, The re-packaging is carried out in such a manner that the re-packaging is carried out.

The asphalt mixture manufactured in the fixed asphalt manufacturing facility is carried by a dump truck. In winter, the temperature of the surface contacting with the outside air is lowered during the transportation process, and the temperature difference between the entire asphalt mixture is generated. In addition, in the section where the asphalt mixture is installed at a relatively low temperature, poor compaction may occur and cause potholes and road breakage.

In addition, since the asphalt mixture is installed in a state where the road surface is cooled, the temperature of the contact surface between the road surface and the asphalt mixture is lowered after the installation of the asphalt mixture, so that the compaction degree of the mixture of the road surface and the asphalt decreases. It is common not to install asphalt pavement in the winter season.

The present inventors have recognized such a problem and have come up with an apparatus capable of manufacturing and packing an asphalt mixture while heating the road surface in the field, as well as an apparatus capable of optimally heating an asphalt mixture when manufacturing an asphalt mixture. In addition, it was possible to produce the asphalt mixture by applying these equipments, and the construction method of paving the road by using this mixture.

It should be understood that the foregoing description of the background art is merely for the purpose of promoting an understanding of the background of the present invention and is not to be construed as adhering to the prior art already known to those skilled in the art.

[ The end of the third feed conveyor belt 230 should be located on the second feed conveyor belt 220 when approaching the facility M.

Meanwhile, the apparatus for manufacturing a mobile asphalt mixture of the present invention may further include a metering sensor S1, a temperature sensor S2, and a controller 900 to implement automation.

The quantitative sensor S1 is installed in each of the first hopper 110 and the second hopper 120 so that the quantity of the material for preparing the asphalt mixture introduced into the first hopper 110 and the amount of the waste asphalt And the control unit 900 compares the measured amount of the waste asbestos and the material for manufacturing the asphalt mixture transferred from the quantitative sensor S1 with the reference amount previously stored in the control unit 900 The apparatus can be automated by transmitting an open signal to the first hopper 110 and the second hopper 120 when the measured amount reaches the reference amount.

The heating unit 400 supplies hot air to the mixer 300 so that the mixer 300 can maintain a specific temperature range. The temperature sensor S2 is installed in the mixer 300. In the control unit 900, Information on the internal temperature of the mixer 300 is received and compared with a previously stored reference temperature, and an opening signal is sent to the outlet O when the reference temperature is reached.

Hereinafter, another embodiment of the structure of the mixer and the movement path of the hot air of the present invention will be described with reference to the accompanying drawings.

5, the mixer 300 of the portable asphalt mixture manufacturing apparatus of the present invention may include a screw mixer 330, an inner chamber 310, and an outer chamber 320.

Inside the inner chamber 310, a mixer may be installed to mix the asphalt mixture and the waste ascon. Various mixers such as a forced mixer, a fan mixer, a twin shaft mixer, a pug mill mixer, a cylindrical mixer, . ≪ / RTI >

The heating unit 400 may include the first heat exchanger H1, the heat exchange box G, and the burner B as described above. The hot air flowing through the gap formed between the inner chamber 310 and the outer chamber 320 indirectly heats the mixture inside the inner chamber 310 and the heat of the burner B flows through the heat exchange box G, (310) to directly heat the mixture. It is preferable to apply the burner B and the heat exchange box G without using a hot air blower to directly heat the mixture. When hot air is used, hot air is blown into the inner chamber 310 or the screw mixer 330, There is a disadvantage in that the time for staying inside decreases and the mixture flows backward by the hot air, which results in a decrease in heating efficiency and a long time for raising the temperature. When the burner (B) and the heat exchange box (G) are used, there is an advantage that the above-mentioned disadvantage can be solved and the temperature rise time can be deducted.

Since the heat circulation path by the mixer 300 and the heating unit 400 shown in FIG. 5 and the structure and principle thereof are the same as those shown in FIG. 2, a detailed description thereof will be omitted.

6, the mixer 300 of the apparatus for manufacturing a mobile asphalt mixture according to the present invention includes an inner chamber 310, an outer chamber 320, and a screw mixer 330, A first screw mixer 331 and a second screw mixer 332 disposed in parallel with the first screw mixer 331 in the longitudinal direction.

The mixer 300 includes a screw mixer 330 The first screw mixer 331 and the second screw mixer 332 and the second screw mixer 332 which are arranged side by side in the longitudinal direction with the first screw mixer 331, And a mixer 333.

When the screw mixer 330 is installed in a multistage manner, waste asbestos cut from the material and the road surface for manufacturing the asphalt mixture are introduced into the first screw mixer 331, the second screw mixer 332, And is mixed and heated while moving in a zigzag manner inside the heat exchanger 333, and is continuously heated by the heat supplied to the inside of the heat exchanger 333 in the moving process.

The first screw mixer 331 to the third screw mixer must have one end or the other end of the first screw mixer in a vertical direction so that the materials move in the lateral direction and then fall down.

FIG. 5 shows a screw mixer 330 of a one-stage structure, FIG. 6 shows a two-stage screw mixer 330 and FIG. 7 shows a three-stage screw mixer 330, Considering the heating efficiency, designers may be able to design more multistage structures.

As shown in FIG. 8, the mixer 300 may include only the screw mixer 330, omitting the inner chamber and the outer chamber. In this case, it is preferable that the screw mixer 330 is designed to have a multi-stage structure. In the present invention, a screw mixer 330 having a five-stage structure in which an inner chamber and an outer chamber are omitted is designed.

The first screw mixer 331 feeds and mixes the material for manufacturing the asphalt mixture and the waste asbestos cut from the road surface through the inlet I formed at one side, and at the same time, transfers the waste ascon to the other side. The waste asphalt cut from the material and the road surface transferred to the other side is dropped and supplied to the second screw mixer 332 and mixed again inside the second screw mixer 332 to be transferred to one side to be dropped, And supplied to the third screw mixer 333.

The material for manufacturing the asphalt mixture supplied to the third screw mixer 333 and the waste asbestos cut from the road surface are mixed again inside the third screw mixer 333 and then transported to one side and dropped to the fourth screw mixer 334 And the above materials are moved in the lateral direction and then supplied to the fifth screw mixer 335 so that they are mixed and moved inside the fifth screw mixer 335 and then discharged.

As described above, the material for manufacturing the asphalt mixture and the waste asbestos cut from the road surface are repeatedly moved and dropped in the first screw mixer 331 to the fifth screw mixer 335, This has the advantage of being improved.

Meanwhile, during passage through the first screw mixer 331 to the fifth screw mixer 335, the material for manufacturing the asphalt mixture and the waste asbestos cut from the road surface are exposed to the heat sufficiently. The fourth screw mixer 334 The heat supplied from the burner B and the heat exchange box G constituting the heating unit 400 is supplied to the fourth screw mixer 334 through the fourth screw mixer 334, And the fifth screw mixer 335 to flow in a direction opposite to the conveying direction of the above-described material.

As described above, the mixing system composed solely of the screw mixer 330 is a direct heating system, in which the heat flows in the direction opposite to the direction of the aggregate movement, and the aggregate is heated by the heat flowing from the bottom to the top. The asphalt is preferably introduced into the first screw mixer 331 or the second screw mixer 332 and the filler and additives may be introduced into the first screw mixer 331.

Hereinafter, a method for preparing a mixture of normal temperature, low temperature, medium temperature and high temperature asphalt mixture using the mobile asphalt mixture manufacturing apparatus of the present invention will be described.

The asphalt mixture at room temperature is mainly used for the base layer and the middle layer. For the surface layer, it is used for the porthole, the section repair, and the front maintenance for the less traffic area. Such a room temperature asphalt mixture, .

The asphalt mixture at room temperature includes at least one aggregate selected from crushed aggregate, asphalt recycled aggregate, and cement concrete crushed aggregate, and at least one filler selected from cement and lime, asphalt, and an additive.

The additive is prepared by mixing at least one process oil selected from aroma oil, paraffin oil and naphtha oil and at least one material selected from SBS, EVA, rosin and petroleum resin and any one selected from kerosene, light oil and gasoline .

The formulation of compositions for making such a room temperature asphalt mixture is described.

The filler is added to filler and the hydration reaction of the aggregate, and is preferably added in an amount of 1 to 10 parts by weight based on 100 parts by weight of the aggregate. When the filler is added in an amount of less than 1 part by weight, the effect of use can not be expected. If the filler is added in an amount of more than 10 parts by weight, the effect to be improved relative to the content is insufficient, which is not economical and workability is deteriorated. .

The additive is preferably mixed with 0.3 to 3 parts by weight based on 100 parts by weight of the aggregate. When the additive is added in an amount of less than 0.3 part by weight, a normal-temperature asphalt mixture can not be prepared. When the additive is added in an amount exceeding 3 parts by weight, the curing time is prolonged and plastic deformation may occur. The additive is used in the range of 0.3 to 1 part by weight when the crushed stone aggregate is used and 0.8 to 3 parts by weight when the recycled aggregate is used.

Such an additive is prepared by mixing 1 to 10 parts by weight of SBS, 1 to 10 parts by weight of EVA, and 1 to 20 parts by weight of at least one material selected from rosin or petroleum resin with respect to 100 parts by weight of the process oil, , A mixed material which is melted and then cooled to room temperature, and 30 to 200 parts by weight of petroleum are mixed into 100 parts by weight of this mixed material at room temperature to prepare a liquid.

If SBS is added in an amount of less than 1 part by weight based on 100 parts by weight of the process oil, the effect of use can not be expected. If added in an amount exceeding 10 parts by weight, the SBS is preferably used in a range of 1 to 10 parts by weight .

When EVA is added in an amount of less than 1 part by weight, the effect of use can not be expected. When the EVA is added in an amount of more than 10 parts by weight, the EVA is preferably used in the range of 1 to 10 parts by weight.

The addition of less than 1 part by weight of rosin or petroleum resin can not improve the workability. If the amount of rosin or petroleum resin is more than 20 parts by weight, rigidity at room temperature results in lowering the quality of the package. Is preferably used.

SBS and EVA are not melted when the heating temperature is lower than 50 占 폚 in the process of manufacturing the additive, and the SBS and the like are oxidized when the temperature exceeds 200 占 폚, so that the heating temperature is controlled in the range of 50 to 200 占desirable.

If petroleum is added in an amount of less than 30 parts by weight based on 100 parts by weight of the above-mentioned mixed material, the flowability of the additive decreases and the workability decreases. If the additive is added in an amount exceeding 200 parts by weight, the room temperature asphalt mixture becomes vulnerable to plastic deformation It is preferable that the addition amount of petroleum is controlled within the above-mentioned range.

The low temperature asphalt mixture can be applied to base layer, middle layer and surface layer, and can be used for porthole, cross section, front repair. Such a low temperature asphalt mixture is produced while maintaining the mixer at a temperature in the range of 50 to 99 캜 by operating the heating part, and is manufactured at a relatively low temperature range and is manufactured and installed while heating the road surface using the above-described apparatus.

The reason for heating the road surface is to maintain the temperature of the asphalt mixture to be heated and stored. When the temperature of the installed asphalt mixture is conserved, the compaction ratio is improved and the quality is also improved. In addition, the adhesion is also improved because the water of the water-soluble adhesive (tack coat, etc.) evaporates.

The low temperature asphalt mixture is produced by operating the heating part and maintaining the mixer in the range of 50 to 99 ° C. It is made of at least one selected from crushed aggregate, asphalt recycled aggregate and cement recycled aggregate, and any one selected from cement, And at least one process oil selected from aroma oil, paraffin oil and naphtha oil, additive mixed with SBS, EVA, rosin or petroleum resin, and asphalt.

The filler is used in an amount of 2 to 10 parts by weight based on 100 parts by weight of the aggregate. When the filler is added in an amount of less than 2 parts by weight, there is no filling effect. When the filler is added in an amount exceeding 10 parts by weight, workability is lowered.

The process oil may be used first to improve workability and is used in a range of 0.1 to 1 part by weight. If the process oil is added in an amount of less than 0.1 part by weight, the effect of use can not be expected. If the process oil is added in an amount exceeding 1 part by weight, plastic deformation may be caused. Therefore, the process oil is preferably used in a range of 0.1 to 1 part by weight.

The additive is added in the range of 1 to 8 parts by weight, and when the recycled aggregate is used, the additive is used in the range of 1 to 4 parts by weight, and when the new aggregate is used, the additive is used in the range of 4 to 8 parts by weight . This is because the effect of using the additive can not be expected when it is used below the lower limit, and the economical efficiency against the increasing effect is lowered when it is used in excess of the upper limit.

Unlike the normal temperature asphalt mixture, the low temperature asphalt mixture is mixed with the asphalt as an additive. That is, 0.5 to 5 parts by weight of SBS, 0.5 to 5 parts by weight of EVA, and 1 to 20 parts by weight of any one material selected from rosin or petroleum resin are mixed and modified asphalt to 100 parts by weight of asphalt.

If SBS and EVA are added in an amount of less than 0.5 part by weight, the effect of use can not be expected. If the amount of SBS and EVA is more than 5 parts by weight, there is a disadvantage in workability and usability. Therefore, SBS and EVA are preferably used in the above- .

If rosin or a petroleum resin is added in an amount of less than 1 part by weight, the effect of improvement in workability can not be expected. If the amount of the rosin or petroleum resin is more than 20 parts by weight, rigidity is exhibited at room temperature, It is preferable to use them in a controlled manner.

The mesophase asphalt mixture is prepared by heating the road surface using the apparatus described above and heating the mixer using a heating unit at a temperature of 100 to 140 ° C.

This mesophase asphalt mixture is applied to base layer, middle layer and surface layer such as KS standard and collective standard standard and can be used for SMA, drainage, low noise, high strength, ultra low noise ascon, and thin layer packing of T = 3cm or less.

The mesophase asphalt mixture may be obtained by mixing at least one aggregate selected from crushed aggregate, asphalt regenerated aggregate and cement regenerated aggregate, and at least one filler selected from cement, slaked lime and quicklime, SBS and process oil, Based on the weight of the additive.

The filler is used in an amount of 2 to 10 parts by weight based on 100 parts by weight of the aggregate, and the additive is used in the range of 0.1 to 1 part by weight based on 100 parts by weight of the aggregate. If asphalt regenerated aggregate is used, the additive is used in an amount of 0.1 to 2 parts by weight based on 100 parts by weight of the recycled aggregate. When the additive is used in an amount less than the lower limit, the effect of using the additive can not be expected. When the additive is used in an amount exceeding the upper limit, the economical efficiency against the increasing effect is lowered.

When the filler is added in an amount of less than 2 parts by weight, the filler function is difficult to manifest. When the filler is added in an amount exceeding 10 parts by weight, workability is lowered.

The additive can be put into the premix type (mixed with asphalt), plant input type (directly into the mixer in powder form). These additives are prepared by mixing 10 to 100 parts by weight of process oil, 5 to 500 parts by weight of rosin and 10 to 200 parts by weight of EVA with respect to 100 parts by weight of SBS.

If the process oil is added in an amount of less than 10 parts by weight, the effect of use can not be expected. If it is added in an amount of more than 100 parts by weight, plastic deformation may be caused.

If rosin is added in an amount of less than 5 parts by weight, the effect of improvement in workability can not be expected. If it is added in an amount of more than 500 parts by weight, rigidity is exhibited at room temperature and packaging quality is lowered. Do.

If EVA is added in an amount of less than 10 parts by weight, the effect of use can not be expected. If the EVA is added in an amount exceeding 200 parts by weight, there is a disadvantage in workability and usability. Therefore, EVA is preferably used within the above-mentioned range.

On the other hand, a rubber chip having a diameter of 3 mm or less, a process oil and a bronze asphalt may be further added to the mesophase asphalt mixture, if necessary.

The rubber chip may be added by selecting at least one of waste tire, EPDM, and urethane.

1 to 5 parts by weight of process oil is mixed at room temperature with respect to 100 parts by weight of the rubber chip, aged for 1 hour or more, and 1 to 10 parts by weight of bronze asphalt is mixed while heating the aged rubber chip at 120 to 200 캜, The aged rubber chip coated with asphalt is put in a powder form in a mixer of 0.3 to 10 parts by weight based on 100 parts by weight of the aggregate.

Addition of less than 1 part by weight of bronze asphalt can not be expected to provide an effect of use, and addition of more than 10 parts by weight of the asphalt is difficult to produce due to adherence between particles, so that the use of the bronze asphalt is preferably within the above- .

When the aged rubber chip coated with bronze asphalt is used as a general modifier, it is used in the range of 0.3 to 1 part by weight, and when it is used for the low-noise, high-strength and ultra-low-noise functioning, 1 to 10 parts by weight is used.

The hot asphalt mixture is prepared by heating the road surface to about 30 to 100 DEG C with the above-mentioned apparatus, and operating the heating unit to heat the mixer to 141 DEG C or higher. Such a hot asphalt mixture is applied to places requiring a high temperature asphalt of 141 ° C or higher, as well as a goosel asphalt mixture of 180 ° C or higher, a waterproof ascon, a high strength ascon, and a thin layer ascon of 3 cm or less.

Among the materials used in the production of the hot asphalt mixture, aggregates are mainly used in crushed aggregate, and fillers are selected from cement, slaked lime and quick lime.

The filler is used in an amount of 2 to 30 parts by weight based on 100 parts by weight of the aggregate. In general, 2 to 10 parts by weight of the filler is used, and 10 to 30 parts by weight of the filler is used in the production of a water- Is preferable because the porosity can be made close to zero.

The additive is prepared by mixing the aged rubber powder (aged by mixing rubber powder and process oil), aged SBS, EVA and rosin as described in the production of mesophase asphalt mixture.

The aged rubber powder is prepared by mixing 1 to 5 parts by weight of process oil with 100 parts by weight of rubber powder and aging at room temperature for 1 hour or more and aging SBS is prepared by mixing 10 to 100 parts by weight of process oil per 100 parts by weight of SBS to obtain 1 Hour.

The additive is prepared by mixing 2 to 10 parts by weight of aged SBS, 2 to 10 parts by weight of EVA, and 2 to 10 parts by weight of rosin with respect to 100 parts by weight of the aged rubber powder, 1 to 40 parts by weight are added.

The reason why the compositions to be added for the production of such a hot asphalt mixture is limited is that the reasons for the above-described room temperature, low temperature, and medium temperature asphalt mixture preparation have already been explained and omitted in order to avoid redundancy.

On the other hand, asphalt mixed for high temperature asphalt mixture is used for road paving asphalt, but it is possible to use at least one of bronze asphalt and trinase asphalt according to the amount of additives.

The mixture of the room temperature asphalt mixture, the low temperature asphalt mixture, the medium temperature asphalt mixture, and the high temperature asphalt prepared by the above-described method may be partially manufactured at the factory and mixed with other materials in the field. Ascon can be used immediately.

In the case of preparing the above-mentioned asphalt mixture, when a color packing is required, a pigment may be added.

Meanwhile, in the construction method using the apparatus for manufacturing a mobile asphalt mixture according to the present invention, a mixture of a room temperature asphalt mixture, a low temperature asphalt mixture, a medium temperature asphalt mixture and a high temperature asphalt mixture prepared by the above-described method is placed on a surface heated to a predetermined temperature range, It is accomplished through the process of making a vigilance by using the dam roller, the tire roller, and the dam roller roller.

A room temperature asphalt mixture (room temperature type ascon) having a particle size of WC-5 is produced using a mobile asphalt mixture preparation apparatus. Atmospheric Ascon pavement is applied to small roads that pass by 100 vehicles a day or less, and these roads are one-lane one way, and the old pavement is aged and the road surface is cut by 5cm and then re-packed to recycle waste ascon , 20% of 10 mm new aggregate and asphalt and regenerating additive were added.

The asphalt pavement ascon produced by using the portable asphalt mixture manufacturing equipment was installed using the asphalt pavement finishing machine and the produced ascon pavement was immediately dropped to the finishing machine so that the production and construction were simultaneously performed.
