본 발명은 도로 포장에 사용되는 아스팔트 콘크리트 혼합물에 친환경적이면서도 결빙방지 효과가 향상된 도로포장용 아스팔트 콘크리트 첨가제를 혼합하여 시공함으로써, 동절기에 내리는 눈 또는 비로 인해 도로의 표면이 결빙되어 발생하는 문제를 효과적으로 저감시키면서, 동시에 주변 토양 및 도로 구조물 등에 영양을 주지 않는 친환경적이면서도 결빙방지 효과가 향상된 도로 포장용 아스팔트 콘크리트 첨가제 및 이를 포함하는 아스팔트 콘크리트 혼합물에 관한 것이다.The present invention mixes the asphalt concrete mixture used for road pavement with an eco-friendly and improved anti-icing asphalt concrete additive for road pavement, thereby effectively reducing the problem caused by freezing of the road surface due to snow or rain falling in winter. , It relates to an eco-friendly asphalt concrete additive for road pavement with improved anti-icing effect and an asphalt concrete mixture containing the same, while at the same time not giving nutrition to surrounding soil and road structures.
경찰청이 발표한 지난 5년간 겨울철 교통사고 통계에 따르면 교통사고 7,236건 중에서 눈길 사고로 인한 사망자는 186명이며, 블랙아이스(black ice) 사고 사망자는 706명으로 눈길 사고 사망자보다 4배가 높았다. 블랙아이스 사망사고가 더 많이 발생한 이유는 도로위의 빙판길에 의해 차량 제어가 어려워, 대형사고로 이어지고 연쇄충돌의 가능성이 높아지기 때문이다.According to winter traffic accident statistics published by the National Police Agency for the past five years, out of 7,236 traffic accidents, 186 people died from snow accidents, and 706 people died from black ice accidents, four times higher than those from snow accidents. The reason why the number of black ice fatalities is higher is that it is difficult to control the vehicle due to the icy road on the road, which leads to a major accident and increases the possibility of a chain collision.
아스팔트 콘크리트 노면의 결빙을 방지하고, 쌓인 눈 또는 얼음을 융해시키고, 노면 상에 형성된 수분의 재결빙을 방지하며, 노면에 달라붙은 눈을 노면으로부터 분리시켜 제설작업의 용이성을 증가시키기 위하여 모래 등의 마찰제 또는 동결 방지제, 융설제를 포함한 제설제를 살포하거나, 제설차량을 이용하여 적설시마다 수시로 눈을 제거하고 있다.To prevent freezing of asphalt concrete road surface, to melt accumulated snow or ice, to prevent re-icing of moisture formed on the road surface, and to separate snow adhered to the road surface from the road surface to increase the ease of snow removal. Snow is removed from time to time by spraying snow removal agents including friction agents, antifreeze agents, and snowmelting agents, or by using a snow removal vehicle.
통상적으로 널리 사용되는 동결 방지제로 사용중인 염화물계 제설제의 경우에는 제설작업을 위하여 도로의 노면이나 교량에 살포될 경우, 상기 염화물계 제설제 내 포함되는 염소 이온(Cl-)과 철(Fe)이 반응하여 염화철(FeCl2)를 생성하고, 이로인해 자동차, 철근, 철골 등을 부식시키거나, 강한 독성으로 인하여 시설구조물의 내구성 저하와, 지하수, 하천 및 토양오염(토양의 산성화)을 유발하고, 주변 초목, 농작물등 식물을 고사시키는 등 생태계에 막대한 영향을 초래하고 있으나 이를 대체할 제품은 미비한 실정이다.In the case of a chloride-based snow removal agent that is commonly used as a widely used anti-freezing agent, chlorine ions (Cl-) and iron (Fe) contained in the chloride-based snow removal agent when sprayed on the road surface or bridge for snow removal work This reaction produces iron chloride (FeCl2), which corrodes automobiles, reinforcing bars, steel frames, etc., or decreases the durability of facility structures due to strong toxicity, and causes groundwater, river and soil contamination (soil acidification), It is causing a huge impact on the ecosystem, such as killing plants, such as surrounding vegetation and crops, but there are insufficient products to replace it.
상기와 같은 문제를 해결하기 위하여 등록특허 제1471837호에서는 제설제 흡수력이 뛰어나며, 도로 포장면의 결빙 현상 및 온도 상승을 효과적으로 방지하고, 자외선 안정성이 높은 다기능성 도로포장 도포재를 제시하였다.In order to solve the above problems, Patent Registration No. 1471837 proposes a multifunctional road pavement coating material that has excellent snow removal ability, effectively prevents icing and temperature rise on the pavement surface, and has high UV stability.
그러나, 상기 종래 기술의 경우 도포재 자체로는 융설 또는 제설효과가 없어, 동절기에 도로 표면상의 결빙억제 및 눈을 녹이기 위해서는 매번 도로 표면상에 제설제를 살포해야하는 문제가 있었다.However, in the case of the prior art, since the coating material itself does not have a snowmelting or snow removal effect, there is a problem that the snow removal agent has to be sprayed on the road surface every time in order to inhibit freezing and melt snow on the road surface in winter.
상기와 같은 문제점을 해결하기 위하여 본 발명은 도로 포장에 사용되는 아스팔트 콘크리트 혼합물에 친환경적이면서도 결빙억제 효과가 향상된 도로포장용 아스팔트 콘크리트 첨가제를 혼합하여 도로포장 시공함으로써, 결빙 현상을 방지하면서도 친환경적인 도로포장용 아스팔트 콘크리트 첨가제를 제공하는 과제를 기초로 한다.In order to solve the above problems, the present invention mixes the asphalt concrete mixture used for road paving with an eco-friendly and improved anti-icing asphalt concrete additive for road pavement construction, thereby preventing icing and eco-friendly asphalt for road paving.

도 1은 본 발명의 실시예에 따른 아스팔트 콘크리트의 결빙 실험결과를 나타낸 것이다.1 shows the results of the freezing test of asphalt concrete according to an embodiment of the present invention.
이하에서는, 본 발명의 바람직한 실시예를 참조하여 상세하게 설명하기로 한다. 다만, 이는 본 발명이 속하는 기술분야에서 통상의 지식을 가진 자가 발명을 용이하게 실시할 수 있을 정도로 상세하게 설명하기 위한 것이지, 이로 인해 본 발명의 기술적 사상 및 범주가 한정되는 것을 의미하는 것은 아니다.Hereinafter, it will be described in detail with reference to preferred embodiments of the present invention. However, this is intended to describe in detail enough that a person of ordinary skill in the art to which the present invention pertains can easily implement the invention, and this does not mean that the technical spirit and scope of the present invention are limited thereto.
먼저, 본 발명의 친환경적이면서도 결빙방지 효과가 향상된 도로포장용 아스팔트 콘크리트 첨가제는 재(ash), 난각, 운모, 코코넛 껍질을 포함할 수 있고, 상기 재, 난각, 운모 및 코코넛 껍질은 모두 평균 입자 크기가 20nm 내지 70nm로 분쇄하여 분말화 된 상태이다.First, the eco-friendly asphalt concrete additive for road pavement with improved anti-freeze effect of the present invention may include ash, egg shell, mica, and coconut shell, and the ash, egg shell, mica and coconut shell all have an average particle size. It is in a powdered state by grinding to 20 nm to 70 nm.
상기 재(ash)는 나무 또는 나뭇잎들을 태우고 남은 것으로 주성분은 칼륨과 탄소이다. 나뭇 또는 나뭇잎들을 태우고 남은 재는 식물의 뿌리를 튼튼하게 해주면서 높은 염기를 함유하고 있어 도로에 눈이 내릴 때 이를 녹이는 역할을 한다. The ash is left over from burning wood or leaves, and its main components are potassium and carbon. Ashes left after burning trees or leaves make the roots of plants strong and contain high bases, so they melt when snow falls on the road.
난각은 잘 말린 계란 껍질을 말한다. 난각의 97%가 무기염류 성분으로, 95%의 칼슘카보네이트(calcium carbonate) 및 적은 양의 마그네슘카보네이트가 포함되어 있어 난각을 구성하는 주요 이온은 Ca2+, Na+, K+, Mg2 + 등의 무기염이다.Eggshell refers to well-dried eggshell. 97% of eggshells are inorganic salts, and 95% of calcium carbonate and a small amount of magnesium carbonate are included . is an inorganic salt of
본 발명의 난각의 무기염은 염화 이온(Cl-)을 포함하지 않고 있으므로 염화 이온이 포함된 염화물로 인한 부식성 또는 독성 문제점, 및 이러한 문제점으로 발생되는 아스팔트 콘크리트의 표면 부식, 강도저하 등의 노후화가 촉진, 차량, 교량 등의 부식 문제가 발생되지 않고 토양오염 문제도 발생되지 않는다.Since the inorganic salt of the eggshell of the present invention does not contain chloride ions (Cl − ), corrosive or toxic problems caused by chloride containing chloride ions, and aging such as surface corrosion and strength reduction of asphalt concrete caused by these problems are reduced. Corrosion problems such as acceleration, vehicles, and bridges do not occur, and there is no soil pollution problem.
따라서 난각은 주변 토양, 지반 및 주변 식물에 영향을 주지 않는 친환경적인 결빙방지용 아스팔트 콘크리트 첨가제 성분이다. 잘 말린 계란 껍질인 난각을 갈아서 흙과 혼합하하면 식물에게 무해하면서도 유익한 비료가 될 정도로 난각(계란 껍질)은 석회질이기 때문에 알칼리 토양에서 잘자라는 식물들에겐 유용한 양분이 될 수 있다.Therefore, eggshell is an eco-friendly anti-freezing asphalt concrete additive component that does not affect the surrounding soil, ground and surrounding plants. If the eggshell, which is a well-dried eggshell, is ground and mixed with soil, it can be a useful nutrient for plants that grow well in alkaline soil because the eggshell (eggshell) is calcareous enough to be a harmless and beneficial fertilizer to plants.
운모(mica)는 2차원적인 층상구조를 갖는 층상 규산염에 속하며, 암석에 흔하게 존재하는 광물이다. 운모의 영어명인 mica는 '부스러기'를 뜻하는 라틴어에서 유래했다. 운모는 일반적으로 운모는 판상으로 갈라지는 특성이 매우 강하며 구조적으로 각 운모층은 1개의 팔면체 단위층과 2개의 사면체 단위층으로 구성되어 있다. 사면체 단위층은 규소를 포함하는 사면체들의 망상구조를 이루며, 각 사면체는 다른 사면체와 3개의 산소 원자를 공유하고 있고, 사면체층 사이에 팔면체 층이 존재한다. Mica belongs to a layered silicate having a two-dimensional layered structure, and is a mineral commonly present in rocks. The English name for mica, mica, comes from the Latin word for 'crumbs'. In general, mica has very strong plate-like properties, and each mica layer is structurally composed of one octahedral unit layer and two tetrahedral unit layers. The tetrahedral unit layer forms a network structure of tetrahedra containing silicon, each tetrahedron shares three oxygen atoms with other tetrahedra, and an octahedral layer exists between the tetrahedral layers.
본 발명은 운모 중에서도 백운모와 금운모 어느 하나 이상을 채택하였는데, 그 이유는 백운모와 금운모는 운모 중에서도 마그네슘을 많이 함유하고 있기 때문이다. The present invention employs at least one of muscovite and phlogopite mica among mica, because muscovite and phlogopite mica contain a lot of magnesium among mica.
또한 운모는 물 분자에서 배제되어 응집되는 소수성 성질(hydrophobicity)을 갖고 있다. 이러한 운모의 소수성 성질은 운모 표면이 거칠고 판상 구조로 갈라져 있기 때문이다.In addition, mica has a hydrophobicity that is excluded from water molecules and aggregates. This hydrophobic property of mica is due to the rough surface of the mica and cracked plate-like structure.
20nm 내지 70nm로 분쇄하여 분말화 된 백운모 또는 금운모는 거친 표면의 층상 구조로 소수성 성질이 강하기 때문에, 도로에 쌓이는 눈이 녹아서 된 물이 도로와 결합하지 못하도록 하여 물이 도로를 흘러서 배수구나 도로 양 옆으로 흐르는 작용을 하게 되어, 도로에 얼음이 어는 것을 방지할 수 있다. Since muscovite or Phosphorus mica pulverized to 20 nm to 70 nm has a strong hydrophobic property with a layered structure with a rough surface, it prevents water from melting snow accumulating on the road from combining with the road, allowing water to flow through the road and It acts as a sideways flow, preventing ice from freezing on the road.
잘 말린 후 20nm 내지 70nm로 분쇄하여 분말화 된 코코넛 껍질은 미세한 다공성 구조의 소수성 성질이 강하여, 눈이 녹은 물이 도로 표면과 결합하지 못하도록 하여 얼음이 어는 것을 방지할 수 있다. 특히 코코넛 껍질은 아스팔트 콘크리트 혼합물에 섞인 뒤에도 미세한 다공성 구조를 거의 그대로 갖고 있어, 물이 도로 표면과 접촉을 못하도록 하는데 탁월한 효과를 보였다.Coconut shells, which are well dried and then pulverized to 20 nm to 70 nm, have a strong hydrophobic property of a fine porous structure, preventing the water from melting snow from bonding with the road surface, thereby preventing the ice from freezing. In particular, the coconut shell has a microporous structure almost intact even after being mixed with the asphalt concrete mixture, so it has an excellent effect in preventing water from coming into contact with the road surface.
코코넛 껍질은 전세계적으로 구하기 쉽고 원료도 친환경적이며 이를 구하는데 아무런 비용이 들지 않는다.Coconut shells are easy to obtain worldwide, and the raw material is environmentally friendly, and there is no cost to obtain them.

아스팔트 콘크리트의 결빙 실험Asphalt Concrete Freezing Experiment
실시예 2의 표 2에 따라 물, 결합재, 골재(잔 골재+굵은 골재), 개질아스팔트 및 첨가제를 혼합하여 30×30×5cm 아스팔트 콘크리트 시편을 제작하였다. 상기 시편의 가장자리를 따라 투명한 필름을 부착하고 시편 상부에 5 mm 두께의 물을부은 다음 평균온도가 -20 ℃인 냉동창고에 1시간 동안 방치하였으며, 방치 중간에 주기적으로 상기 시편의 상부의 전체면적 중 결빙이 형성된 면적을 측정하였다. 그 결과는 도 1과 같다. According to Table 2 of Example 2, water, binder, aggregate (fine aggregate + coarse aggregate), modified asphalt and additives were mixed to prepare a 30 × 30 × 5 cm asphalt concrete specimen. A transparent film was attached along the edge of the specimen, 5 mm thick water was poured on the top of the specimen, and then left in a freezer with an average temperature of -20 ° C. The area where heavy ice was formed was measured. The result is shown in FIG. 1 .
도 1의 결과에 따르면 아스팔트 콘크리트 첨가제가 포함된 실시예 2-1, 2-2이 비교예 2-1 및 2-2가 첨가제가 포함되지 않은 비교예 2-3보다 낮은 결빙율을 보인다는 것을 확인할 수 있다. 또한 본 발명의 아스팔트 콘크리트 첨가제가 포함된 실시예 2-1 및 2-2가 비교예 2-1(코코넛 껍질을 포함하지 않은 비교예 1-1의 첨가제를 혼합한 아스팔트 콘크리트 혼합물) 및 비교예 2-2(금운모를 포함하지 않은 비교예 1-2의 첨가제를 혼합한 아스팔트 콘크리트 혼합물) 보다 낮은 결빙율을 보인다.According to the results of FIG. 1 , it was found that Examples 2-1 and 2-2 containing the asphalt concrete additive showed a lower freezing rate than Comparative Examples 2-1 and 2-2 of Comparative Examples 2-3 without the additive. can be checked In addition, Examples 2-1 and 2-2 containing the asphalt concrete additive of the present invention are Comparative Example 2-1 (asphalt concrete mixture containing the additive of Comparative Example 1-1 without coconut shell) and Comparative Example 2 It shows a lower freezing rate than -2 (asphalt concrete mixture mixed with the additive of Comparative Example 1-2 that does not contain phloem mica).
또한 다공질체인 금운모가 포함되지 않는 첨가제를 사용한 비교예2-2의 경우에는 초반에는 결빙 형성이 낮았으나, 점차 시간이 경과함에 따라 결빙된 면적이 급격히 증가하였다.Also, in the case of Comparative Example 2-2, in which an additive containing no phosphite mica, which is a porous body, was used, ice formation was low at the beginning, but the frozen area rapidly increased as time passed.
