일반적으로, 아스팔트 포장(asphalt pavement) 또는 콘크리트 포장(concrete pavement)은 도로 포장의 일례로, 아스팔트 포장은 골재를 역청 재료로 결합하여 만든 표층을 가진 포장으로써, 표층기층 및 노반으로 이루어지는 것이고, 콘크리트 포장은 시멘트 콘크리트로 노면을 덮는 도로포장을 의미하며 표층에 해당하는 콘크리트 슬래브와 중간층, 보조기층으로 구성되어 있다.In general, asphalt pavement or concrete pavement is an example of road pavement. Asphalt pavement is a pavement with a surface layer made by combining aggregate with bitumen material, consisting of surface layer and subgrade. Means road pavement covering the road surface with cement concrete, and it is composed of concrete slab corresponding to the surface layer, middle layer, and auxiliary base layer.
이 중, 아스팔트 포장은 지반 침하에 대한 적응성이 우수하고, 적설한랭지역 제설 융빙에 유리하며, 쾌적성 및 소음 저감에 유리할 뿐만 아니라, 시공 및 유지관리가 쉽고 교통개방을 빨리할 수 있어 교통흐름에 지장이 없는 등의 장점이 있는 반면, 균열, 포토홀, 소성 변형 등의 문제점이 있다.Among them, the asphalt pavement has excellent adaptability to ground subsidence, favorable for snow melting and melting in snowy cold areas, favorable for comfort and noise reduction, easy construction and maintenance, and quick opening of traffic. While there are advantages such as no trouble, there are problems such as cracks, photo holes, and plastic deformation.
한편, 콘크리트 포장은, 중차량에 대한 적응성 우수, 내구성 및 경제성 측면에서 다소 유리한 장점이 있는 반면, 승차감 및 쾌적성에 불리, 균열, 동결융해에 의한 파손, 알칼리 골재반응에 의한 파손 등의 문제점이 있다.On the other hand, concrete pavement has some advantages in terms of adaptability to heavy vehicles, durability and economy, while disadvantageous to ride comfort and comfort, cracks, breakage due to freeze-thawing, breakage due to alkali aggregate reaction, etc. .
최근에는, 대형 차량의 교통량 증가로 인해 가열 아스팔트 포장의 소성변형 문제가 급속히 증가하는 추세이며, 또한 가열 아스팔트 포장 건설에 따른 대기오염 문제가 이슈화되고 있고, 폐아스콘의 폐기물 처리 문제가 고민거리로 등장하고 있다. 상기 소성변형 문제점에 대한 하나의 대안으로서 굵은 골재로 된 아스팔트 포장(공극이 20-25%)을 먼저 시공한 후, 형성된 공극에 시멘트 슬러리(slurry)를 주입시켜 경화시킨 반강성 포장이 일본에서 개발되어 사용되고 있지만, 이 방법은 두 단계의 공정을 거쳐야 하므로 비용이 비싸며, 시공기간도 상대적으로 길다는 문제점이 있다. In recent years, the plastic deformation problem of heated asphalt pavement is increasing rapidly due to the increase of traffic volume of large vehicles, and the air pollution problem caused by the construction of heated asphalt pavement has been raised, and the problem of waste disposal of waste ascon has appeared as a problem. Doing. As an alternative to the plastic deformation problem, semi-rigid pavement developed by coarse aggregate asphalt pavement (20-25% of voids) was first formed and then hardened by injecting cement slurry into the formed voids. Although this method has been used, it is expensive because it requires a two-step process, and there is a problem in that the construction period is also relatively long.
따라서, 최근에는 시공공정이 단순하면서도 공해문제도 해결할 수 있는, 시멘트, 유화 아스팔트 및 골재로 구성된 상온 반강성 포장이 유력한 재료로 개발되고 있다. 여기서 반강성 포장이라 함은 아스팔트의 연성과 시멘트의 강성이 함께 공존하는 포장을 말하며, 아스팔트 포장보다 강성은 우세하나 연성은 떨어지고, 시멘트 포장보다 연성은 향상되지만 강성은 다소 떨어지는 포장을 말한다. 예컨대, 등록특허공보 제10-0599492호에는 폐아스콘을 활용한 반강성포장용 조성물과 포장시공방법이 개시되어 있고, 등록특허공보 제10-0767989호에는 상온 반강성 도로 포장 방법 및 도로 포장재가 개시되어 있다.Therefore, recently, the room temperature semi-rigid pavement consisting of cement, emulsified asphalt, and aggregate, which can simplify the construction process and solve the pollution problem, has been developed as a strong material. Here, the semi-rigid pavement refers to a pavement in which both the ductility of asphalt and the stiffness of cement coexist. The stiffness is superior to the asphalt pavement, but the ductility is inferior, and the ductility is improved but the stiffness is slightly lower than the cement pavement. For example, Korean Patent No. 10-0599492 discloses a semi-rigid packaging composition and paving method using waste ascon, and Korean Patent No. 10-0767989 discloses a room temperature semi-rigid road paving method and a road paving material. have.
한편, 건설폐자재는 건축물 재건축, 도심재개발, 도로 개보수공사, 도로굴착 및 복구공사 등에서 발생되며, 일반적으로 시멘트콘크리트류(폐콘크리트), 아스팔트콘크리트류(폐아스팔트 콘크리트), 토사류(폐토사), 목재, 철재 등으로 분류되며, 매년 발생량이 크게 증가되고 있다.On the other hand, construction waste materials are generated from building reconstruction, urban redevelopment, road renovation, road excavation and recovery, etc.In general, cement concrete (waste concrete), asphalt concrete (waste asphalt concrete), earth and sand (waste soil), wood It is classified into steel, and the amount of generation is greatly increased every year.
현재 건설폐자재는 대부분 단순 매립하거나 폐기되고 있는 실정이며, 일부에서 외국의 기술을 직접 도입하거나 개발하여 재활용하고 있으나 발생 및 처리과정의 체계가 미비하고 재활용 재료를 설계에 적용하기 위한 체계적인 기준이 미비하기 때문에 재활용률이 저조한 실정이다. Currently, most of construction waste materials are simply landfilled or discarded, and some have introduced or developed foreign technologies directly, but they have been developed and recycled. However, the system of generation and disposal process is inadequate and there is no systematic standard for applying recycled materials to design. Therefore, the recycling rate is low.
따라서, 도로에서 발생되거나 이미 발생하여 중간처리업체의 적치장에 쌓여있는 폐아스팔트 콘크리트 등의 적절한 재활용 방안을 모색하고, 이를 활성화하여 자원의 재활용에 따른 경제적인 이점과 동시에 환경 문제를 해결할 수 있는 방안이 필요하게 되었다.Therefore, it is necessary to find a suitable recycling method for waste asphalt concrete, which has been generated on the road or already occurred and accumulated in the stockyard of an intermediate processing company, and by activating it, it is possible to solve economic problems and environmental problems at the same time. It became necessary.
이에, 시멘트 콘크리트류(폐콘크리트), 아스팔트 콘크리트류(폐아스팔트 콘크리트) 등과 같은 폐자재를 이용하여 아스팔트 콘크리트 조성물을 제조함으로써 자원을 재활용하는 기술이 개발되고 있으며, 예컨대, 등록특허공보 제10-0341021호에서는 폐유리를 골재로 사용한 아스팔트 콘크리트 조성물의 제조방법을 개시하고 있고, 공개특허공보 제10-2008-0009335호에서는 폐아스팔트 콘크리트를 활용한 도로포장용 상온 아스팔트콘크리트(상온 아스콘)을 개시하고 있으며, 등록특허공보 제10-0946588호에서는 상온 재생 아스팔트 콘크리트 조성물 및 그 시공방법을 개시하고 있다.Accordingly, a technology for recycling resources by manufacturing asphalt concrete compositions using waste materials such as cement concrete (waste concrete) and asphalt concrete (waste asphalt concrete) has been developed. For example, Korean Patent Publication No. 10-0341021 Korean Patent Publication No. 10-2008-0009335 discloses a method for producing asphalt concrete composition using waste glass as an aggregate, and discloses a room temperature asphalt concrete (room temperature ascon) using waste asphalt concrete. Korean Patent Publication No. 10-0946588 discloses a room temperature regenerated asphalt concrete composition and its construction method.
그러나, 석탄연료 등의 소모가 거의 없어 이산화탄소 등의 유해가스의 배출이 없는 방식으로 시공이 가능하면서도, 폐아스팔트 콘크리트를 사용하여 친환경적인, 재활용 상온 반강성 아스팔트 콘크리트에 관한 기술은 알려져 있지 않다. However, the construction of semi-rigid asphalt concrete, which is environmentally friendly and uses waste asphalt concrete, is not known because it can be constructed in such a way that there is almost no consumption of coal fuel and no emissions of harmful gases such as carbon dioxide.
따라서, 상온에서 시공이 가능하여 가열 과정을 생략함으로써, 가열로 인한 유해가스가 발생되는 등의 문제점을 해결할 수 있으면서도, 폐아스팔트 콘크리트를 사용하여 친환경적이고 포장의 내구성이 뛰어난 재활용 상온 반강성 아스팔트 콘크리트 조성물 및 그 제조방법에 관한 기술의 지속적인 개발이 필요한 실정이다.Therefore, the construction can be carried out at room temperature, eliminating the heating process, while solving the problems such as the generation of harmful gases due to the heating, recycled room temperature semi-rigid asphalt concrete composition using environmentally friendly and durable pavement using waste asphalt concrete And it is a situation that requires the continuous development of the technology for the manufacturing method.
