Description
본 발명은 노후된 노면을 파쇄한 후 다시 포장하기 위한 것으로, 보다 상세하게는 파쇄된 아스팔트를 현장에서 즉시 재생하여 포장할 수 있는 아스팔트 재생 포장용 복합 폴리머 바인더 및 그 제조방법, 그리고 이를 이용한 재생 아스팔트 포장방법에 관한 것이다.The present invention is for paving again after crushing an aged road surface, and more particularly, a composite polymer binder for asphalt recycling pavement that can immediately regenerate and pave crushed asphalt in the field, a method for manufacturing the same, and a regenerated asphalt pavement method using the same It is about.
통상적으로, 아스팔트(또는 아스팔트 콘크리트)는 신규 아스팔트와 재생 아스팔트로 구분하며, 이때, 재생 아스팔트는 공장 재생 아스팔트와 현장 재생 아스팔트로 구분한다.Typically, asphalt (or asphalt concrete) is classified into new asphalt and recycled asphalt, and at this time, the recycled asphalt is divided into factory-regenerated asphalt and on-site recycled asphalt.
공장 재생 아스팔트는 도로 공사 현장에서 파쇄된 폐 아스팔트를 공장으로 운송한 후, 이에 여러 첨가제를 투입하고 가열하여 재생한 후, 재생 아스팔트를 다시 도로 공사 현장으로 운송하여 시공하므로, 공정 시간이 지나치게 오래 소요되고 운송 과정에서 폐 아스팔트의 분진, 재생 아스팔트의 유독 증기에 의한 주변 환경오염 우려가 있다.Factory regenerated asphalt is constructed by transporting waste asphalt crushed at the road construction site to the factory, adding various additives to it, heating it, and then transporting the regenerated asphalt back to the road construction site for construction, so the process takes an excessively long time. In the process of transportation, there is a risk of contamination of the surrounding environment by dust from waste asphalt and toxic vapor from recycled asphalt.
이에 비해, 현장 재생 아스팔트는 도로 공사 현장에서 노후 아스팔트 포장을 절삭 및 파쇄한 후에, 재생첨가제를 투입하여 혼합 및 포장하는 공정을 거쳐 시공된다.In comparison, on-site regeneration asphalt is constructed by cutting and crushing old asphalt pavement at a road construction site, then mixing and paving by adding a regeneration additive.
이와 같은 현장 재생 아스팔트는 아스팔트 포장의 노후 표층 현장에서 가열하여 그 자리에서 파쇄한 후, 재생첨가제를 투입하고, 추가적인 가열 없이 혼합하여 아스팔트 포장용 포설 설비에 투입하여 포설 및 다짐하여 완성되므로, 공장 재생 아스팔트에 비해 운송 등 여러 공정이 생략되고, 운반 공정에서 발생되는 유해물질에 의한 공기오염 등을 방지할 수 있고, 원가절감과 공사비를 절감할 수 있는 등 다양한 장점이 있다.Such in-situ regenerated asphalt is completed by heating the old surface layer of the asphalt pavement, crushing it on the spot, adding a reclaimed additive, mixing it without additional heating, putting it into an asphalt pavement laying facility, and laying and compacting. Compared to this method, various processes such as transportation are omitted, air pollution caused by harmful substances generated in the transportation process can be prevented, and cost reduction and construction costs can be reduced.
그러나 종래의 현장 재생 아스팔트는, 그 제조 공정 중에 아스팔트 노면을 가열하거나, 폐 아스팔트와 재생첨가제를 가열 믹서를 이용하여 고온에서 혼합하여 제조되는 바, 고온 가열에 따라 노화된 아스팔트는 포장의 수명이 점차 짧아지기 때문에 결국 폐기물로 처리할 수밖에 없게 된다.However, conventional on-site regeneration asphalt is produced by heating the asphalt road surface during the manufacturing process or by mixing waste asphalt and a regeneration additive at a high temperature using a heating mixer. Because it is shortened, it has no choice but to be disposed of as waste in the end.
또한, 공정 중에 아스팔트를 120℃ 이상의 고온으로 가열하는 바, 가열을 위한 연료가 소모될 뿐만 아니라 아스팔트의 일부가 연소, 산화, 노화되어 품질이 저하되는 문제가 있었다.In addition, since the asphalt is heated to a high temperature of 120 ° C. or higher during the process, not only fuel for heating is consumed, but also a part of the asphalt is burned, oxidized, and aged, resulting in deterioration in quality.
이를 보완하기 위해 절삭시 아스팔트를 가열하는 표층 가열에 더해, 가열 믹서를 이용하여 재생첨가제를 투입하는 기술이 개발되었지만, 이 역시 믹서를 가열하기 위한 별도의 발열수단이 요구되고, 가열에 의한 아스팔트의 노후화가 진행되는 문제가 여전히 상존하였다.In order to compensate for this, in addition to surface layer heating that heats asphalt during cutting, a technology for adding regeneration additives using a heating mixer has been developed, but this also requires a separate heating means to heat the mixer, and The problem of aging still existed.
따라서, 파쇄 이후 포장재를 제조하는 공정 중에 별도의 가열 없이 상온에서 혼합 및 반응을 수행할 수 있고, 폐골재(폐아스팔트)간의 접착은 물론, 폐골재와 노면 사이의 접착력이 우수하여 노면에 별도의 접착제를 도포하지 않아도 포장을 수행할 수 있는, 새로운 바인더 및 이를 이용한 포장방법이 요구되고 있는 실정이다.Therefore, during the process of manufacturing pavement materials after crushing, mixing and reaction can be performed at room temperature without additional heating, and the adhesion between waste aggregate (waste asphalt) as well as between the waste aggregate and the road surface is excellent, so that the road surface can be separated separately. There is a demand for a new binder and a packaging method using the same, which can perform packaging without applying an adhesive.

1차 중합이 완료된 이후, 추가적으로 75~78℃에서 3~4시간 동안 2차 중합시키는 단계;를 거치게 된다.After the primary polymerization is completed, additional secondary polymerization at 75 to 78 ° C. for 3 to 4 hours; is performed.
2차 중합시키는 단계가 종료된 이후, NCO%가 15~16%일 경우 55~60℃로 냉각하여 폴리머 바인더를 제조할 수 있다.After the secondary polymerization step is completed, when the NCO% is 15 to 16%, the polymer binder may be prepared by cooling to 55 to 60° C.
상술한 바와 같이 용융하는 단계, 1차 중합시키는 단계 및 2차 중합시키는 단계를 거쳐 폴리머 바인더를 제조한 후, 이에 첨가제를 투입하여 본 발명에서 의도하는 복합재 폴리머 바인더를 제조하게 된다.As described above, after the polymer binder is prepared through the melting step, the primary polymerization step, and the secondary polymerization step, additives are added thereto to prepare the composite polymer binder intended in the present invention.
첨가제를 투입하는 과정은, 폴리머 바인더에 상술한 성분의 첨가제를 투입한 후, 55~60℃에서 30~60분 동안 저속 교반하여 혼합하는 것이 바람직하다.In the process of adding the additives, it is preferable to add the additives of the above components to the polymer binder and mix them by stirring at low speed for 30 to 60 minutes at 55 to 60°C.
이때 저속 교반은 500~600RPM 속도의 교반을 의미하며, 일반적인 고속 교반에 비해 첨가제의 활성도를 증가시킬 수 있어, 반응 효율을 증대시킬 수 있다.At this time, low-speed stirring means stirring at a speed of 500 to 600 RPM, and can increase the activity of additives compared to general high-speed stirring, thereby increasing reaction efficiency.
또한, 본 발명에 따른 아스팔트 재생 포장용 복합 폴리머 바인더는, 상술한 방법에 의하여 제조되는 것을 특징으로 한다. 그 구체적인 성분 및 각각의 구성에 대해서는 상술한 제조방법에서 설명한 바, 여기에서는 중복되는 내용을 생략하도록 한다.In addition, the composite polymer binder for asphalt regeneration pavement according to the present invention is characterized in that it is manufactured by the method described above. The specific components and respective configurations have been described in the above-described manufacturing method, and redundant content will be omitted here.
도 2는 본 발명의 일 실시예에 따른 재생 아스팔트 포장방법의 순서도이다.2 is a flow chart of a recycled asphalt pavement method according to an embodiment of the present invention.
도 2에 도시된 바와 같이, 아스팔트 재생 포장용 복합 폴리머 바인더를 이용한 재생 아스팔트 포장방법은, 노면을 파쇄하여 폐골재를 획득하는 과정, 노면을 청소 및 건조하는 과정, 폐골재에 아스팔트 재생 포장용 복합 폴리머 바인더를 혼합하여 포장재를 제조하는 과정, 포장재를 노면에 포설하는 과정 및 로올러로 다짐하는 과정을 포함한다.As shown in FIG. 2, the recycled asphalt pavement method using the composite polymer binder for asphalt recycling pavement includes a process of crushing the road surface to obtain waste aggregate, a process of cleaning and drying the road surface, and a composite polymer binder for asphalt recycling pavement in the waste aggregate. It includes a process of manufacturing a pavement by mixing, a process of laying the pavement on the road surface, and a process of compacting with a roller.
노면을 파쇄하여 폐골재를 획득하는 과정은, 바브켓(Bobcat) 또는 노면 파쇄기를 이용하여 재 포장이 필요한 부위의 노면을 파쇄하는 공정으로서, 파쇄된 노면의 폐골재는 후속 공정을 통해 재생되어 재활용된다.The process of obtaining waste aggregate by crushing the road surface is a process of crushing the road surface in the area requiring resurfacing using a Bobcat or a surface crusher, and the waste aggregate of the crushed road surface is regenerated and recycled through a subsequent process. do.
이때, 파쇄 과정에서 폐골재의 크기가 5~8mm로 되도록 함으로써, 후술할 포장재 제조 과정 및 포설 과정에 적합한 크기의 폐골재를 획득할 수 있다.At this time, by making the size of the waste aggregate 5 to 8 mm in the crushing process, it is possible to obtain waste aggregate of a size suitable for the paving material manufacturing process and laying process to be described later.
노면을 청소 및 건조하는 과정은, 바브켓의 솔을 이용하여 모래, 흙, 먼지 등 이물질을 1차적으로 제거하고, 물 또는 에어를 분사하여 파쇄면을 깨끗하게 청소하게 된다. 청소 이후에, 만약 물을 사용했다면 물이 완전히 건조되도록 노면을 가열하여 파쇄된 노면에 수분이 존재하지 않도록 하는 것이 바람직하다.In the process of cleaning and drying the road surface, foreign substances such as sand, soil, and dust are primarily removed using the brush of the baby kit, and the crushed surface is cleaned by spraying water or air. After cleaning, if water is used, it is desirable to heat the road surface so that the water is completely dry so that no moisture is present on the fractured road surface.
이후, 통상적인 도로 포장 또는 재생 포장 공정의 경우, 이 시점에서 아스팔트 유제 또는 콘크리트 프라이머를 살포하여, 골재가 노면에 정착하도록 보조하는 접착제를 사용하는 반면, 본 발명에서는 이 공정을 생략하고 재생 포장재를 제조하게 된다.Then, in the case of a normal road pavement or reclaimed pavement process, an asphalt emulsion or a concrete primer is sprayed at this point to use an adhesive to assist the aggregate to settle on the road surface, whereas in the present invention, this process is omitted and the reclaimed pavement material is used. will manufacture
이는 본 발명에 따른 아스팔트 재생 포장용 복합 폴리머 바인더가 폐골재간의 접착 용도의 바인더로도 기능하지만, 포장재와 노면 사이의 접착을 위한 바인더로서도 기능할 수 있기 때문이다.This is because the composite polymer binder for asphalt regeneration pavement according to the present invention functions as a binder for adhesion between waste aggregates, but also functions as a binder for adhesion between pavement materials and the road surface.
따라서, 본 발명에서는 별도의 접착제 도포 없이 도로의 재생 포장이 가능하여 공정 시간을 단축할 수 있고, 접착제의 원료 소요 및 접착제 도포를 위한 장비 소요를 절감할 수 있어 보다 효율적인 도로 포장이 가능해진다.Therefore, in the present invention, it is possible to re-pave the road without additional application of adhesive, thereby reducing the process time, reducing the need for raw materials for the adhesive and equipment for applying the adhesive, thereby enabling more efficient road pavement.
포장재를 제조하는 과정은, 노면을 파쇄한 후 획득한 폐골재와, 앞서 설명한 아스팔트 재생 포장용 복합 폴리머 바인더의 제조방법에 따라 제조된 복합 폴리머를 혼합하여 포장재를 마련하게 된다.In the process of manufacturing the pavement material, the pavement material is prepared by mixing the waste aggregate obtained after crushing the road surface and the composite polymer manufactured according to the method for manufacturing the composite polymer binder for asphalt regeneration pavement described above.
이때, 폐골재 100중량부 대비, 폴리머 바인더와 첨가제를 포함하는 복합 폴리머 바인더 3~10중량부를 혼합하는 것이 바람직하다.At this time, it is preferable to mix 3 to 10 parts by weight of a composite polymer binder containing a polymer binder and an additive with respect to 100 parts by weight of waste aggregate.
복합 폴리머 바인더의 함량이 5중량부 미만일 경우 폐골재간 결합 및 노면 정착을 위한 바인더 역할을 할 수 없고, 8중량부를 초과할 경우 건조 및 경화에 시간이 오래 소요될 뿐만 아니라, 표면에 바인더가 부상하여 미끄러움을 유발할 수 있는 문제가 있다.If the content of the composite polymer binder is less than 5 parts by weight, it cannot serve as a binder for bonding between waste aggregates and fixing the road surface, and if it exceeds 8 parts by weight, it takes a long time to dry and harden, and the binder floats on the surface There are problems that can cause slippage.
또한, 이렇게 포장재를 제조하는 과정은, 폐골재 및 포장재를 자동으로 계량하여 투입 후 혼합하는 자동 계량 믹서기를 이용하는 것이 바람직하다.In addition, in the process of manufacturing the packaging material, it is preferable to use an automatic weighing mixer that automatically weighs the waste aggregate and the packaging material, inputs them, and then mixes them.
도 3에 도시된 자동 계량 믹서기를 참조하여, 본 발명에 따른 재생 아스팔트 포장재를 제조하는 과정은, 중량측정부(300)를 구비한 믹서(100) 내부에 골재를 투입하여 그 투입 중량을 측정하는 단계와, 골재가 투입된 이후 폴리머 바인더 및 첨가제를 투입하여 그 투입 중량을 측정하는 단계와, 골재, 폴리머 바인더 및 첨가제를 믹서(100)에서 혼합하는 단계와, 혼합된 포장재를 배출하는 단계를 포함하여 진행되는 것이 바람직하다.Referring to the automatic metering mixer shown in FIG. 3, the process of manufacturing the recycled asphalt pavement according to the present invention is to put the aggregate into the
이러한 자동 계량 믹서기를 사용함으로써, 원하는 양의 골재, 폴리머 바인더 및 첨가제를 정확하게 투입할 수 있기 때문에, 별도의 중량 측정용 장치가 불필요하고, 미리 골재와 폴리머 바인더 및 첨가제를 일정 비율씩 소분하여 준비할 필요가 없으며, 현장에서 즉시 필요한 양만큼 투입하여 포장재를 혼합 제조할 수 있게 된다.By using this automatic metering mixer, since it is possible to accurately input the desired amount of aggregate, polymer binder and additives, there is no need for a separate weighing device, and it is possible to prepare the aggregate, polymer binder and additives in advance by subdividing them in a certain ratio. It is not necessary, and it is possible to mix and manufacture packaging materials by immediately inputting the required amount on the site.
이때, 믹서(100)의 내부에 설치된 블레이드(110)는 모터(200)의 동력을 받아 회전하면서 골재의 표면에 폴리머 바인더 및 첨가제가 고르게 코팅될 수 있도록 동작한다.At this time, the
모터(200)와 블레이드(110)의 회전축은 직결 연결될 수도 있고, 별도의 벨트나 기어 등으로 연결되어 작동될 수도 있다.The rotation shaft of the
중량측정부(300)는 믹서(100) 및 모터(200) 등을 전체적으로 지지하며, 믹서(100) 내부가 비어 있을 경우에 측정 중량을 0으로 설정함으로써, 투입되는 골재와 폴리머 바인더 및 첨가제의 양을 용이하게 측정할 수 있다.The weighing
중량측정부(300)는 예를 들어 로드셀 타입일 수 있고, 아날로그 타입의 무게 저울을 사용해도 무방하다.The
믹서(100)의 측면에는 포장재를 배출하기 위한 슈트(120)가 설치되어 있는데, 혼합이 완료된 후 포장재를 배출할 때에는 유압 실린더(131)를 작동시켜 도어(132)를 개방함으로써 포장재가 슈트(120)를 통해 포장이 필요한 도로에 직접 배출할 수 있다.A
한편, 도 3에 도시되어 있지는 않지만, 자동 계량 믹서에는 폐골재를 수용하는 호퍼와, 복합 폴리머 바인더를 저장하는 탱크가 추가적으로 설치되는 바, 호퍼로부터 믹서(100)로 공급되는 폐골재의 중량을 실시간으로 측정하고, 이에 따라 복합 폴리머 바인더를 공급량을 자동으로 설정한 후, 이 양이 공급될 만큼 탱크를 개방하여 폴리머 바인더를 공급하는 것이 바람직하다.On the other hand, although not shown in FIG. 3, the automatic metering mixer is additionally installed with a hopper for accommodating waste aggregate and a tank for storing a composite polymer binder, and the weight of waste aggregate supplied from the hopper to the
이를 통해, 폐골재와 복합 폴리머 바인더를 동시에 공급함으로써, 특히 폐골재와 복합 폴리머 바인더를 번갈아 공급할 때에 비해 쏠림 현상이 완화되어 보다 균일한 혼합을 수행할 수 있다.Through this, by simultaneously supplying the waste aggregate and the composite polymer binder, in particular, compared to the case of supplying the waste aggregate and the composite polymer binder alternately, the leaning phenomenon can be alleviated and more uniform mixing can be performed.
한편, 복합 폴리머 바인더는 액상으로 마련되어 유동성이 뛰어나므로, 폐골재와 복합 폴리머 바인더를 혼합하여 포장재를 제조하는 과정에서, 믹서나 원료 등에는 별도의 가열이 필요하지 않고 일반적인 상온 조건, 더 구체적으로 0~40℃에서 혼합을 수행할 수 있다.On the other hand, since the composite polymer binder is provided in a liquid state and has excellent fluidity, in the process of manufacturing a packaging material by mixing the waste aggregate and the composite polymer binder, separate heating is not required for the mixer or raw material, and general room temperature conditions, more specifically 0 Mixing can be performed at -40 °C.
포장재를 제조한 이후, 바브켓 또는 아스팔트(콘크리트) 피니셔를 이용하여 포장재를 노면에 포설하고, 이를 콤비 로올러로 다짐하며, 2~3시간의 경화 이후 바로 도로 사용이 가능하여 도로 폐쇄 시간을 최소화할 수 있다.After manufacturing the pavement, the pavement is laid on the road surface using a barbket or asphalt (concrete) finisher, compacted with a combi roller, and after curing for 2 to 3 hours, the road can be used immediately, minimizing road closure time. can do.
