[규칙 제26조에 의한 보정 29.11.2018]　도로 포장용 결빙방지 표면처리 조성물 및 이를 이용한 도로 포장 결빙방지 표면 처리 방법[Revision 29.11.2018] According to Rule 26. Anti-freezing surface treatment composition for road pavement and road pavement prevention surface treatment method using the same
일반적으로 도로의 포장방법에는 아스팔트 콘크리트 포장 방법과 시멘트 콘크리트 포장 방법으로 크게 나누어지고 있다. 아스팔트 포장은 연성으로서 승차감이 좋고 소음이 적어 보편적으로 많이 사용되고 있지만, 중대형 차량이 통행하게 되면 포장이 파손되고, 타이어의 마찰로 인해 아스팔트 피복이 쉽게 벗겨지며, 바퀴자국 패임(Rutting)이나 소성변형 등의 영구변형이 쉽게 발생하여 수시로 유지보수가 필요하고, 수명이 단축되며, 그로 인해 도로의 유지보수 비용이 증가하고, 교통소통에 장애를 유발하는 문제점이 있다. In general, road pavement is divided into asphalt concrete pavement method and cement concrete pavement method. Asphalt pavement is ductile and has a good ride quality and low noise, so it is commonly used.However, when a large and medium-sized vehicle passes, the pavement is damaged, the asphalt coating is easily peeled off due to the friction of tires, rutting, plastic deformation, etc. Permanent deformation of the easily occurs, often require maintenance, shorten the life, thereby increasing the maintenance cost of the road, there is a problem that causes a disturbance in traffic communication.
한편, 콘크리트 포장 방법은 강성을 갖는 포장 방법으로서 시공 및 양생기간이 길고, 건조수축에 의한 균열이 발생되는 경우가 많으며, 보행 및 주행 안정성과 쾌적성이 떨어지는 단점이 있다.On the other hand, concrete pavement method is a pavement method having rigidity, construction and curing period is long, cracks are often generated due to dry shrinkage, there is a disadvantage in walking and running stability and comfort.
한편, 동절기에 눈이 내리면 결빙이 되기 쉽고, 이렇게 결빙이 되는 경우에는 차량 사고와 보행자의 안전사고가 발생될 수 있으므로 도로에 쌓인 눈을 신속히 융설하여 도로가 결빙되는 것을 방지할 필요가 있으며, 특히 최근 이상 기상 현상에 따라 기록적인 폭설현상이 빈번히 발생되고 있으므로 이와 같은 겨울철 도로의 결빙방지에 대하여 많은 관심을 기울이고 있다.On the other hand, if it snows in winter, it is easy to freeze, and if this freezes, vehicle accidents and pedestrian safety accidents may occur, so it is necessary to quickly melt snow accumulated on the road to prevent the road from freezing. Recently, since heavy snow phenomenon occurs frequently due to abnormal weather phenomenon, much attention has been paid to the prevention of such freezing of winter roads.
또한, 종래 미끄럼 방지 포장재 또는 아크릴공중합수지를 바인더로 한 미끄럼 방지제로 시공한 미끄럼방지구간에도 눈이 쌓이거나 결빙되어 차량의 미끄럼 사고를 유발함으로써 동절기 교통 사고의 주된 요인이 되고 있다. 이와 같이, 눈이 쌓이거나 결빙을 방지하기 위해 현재는 도로에 모래를 뿌리거나 염화칼슘 등을 뿌리는 방법이 사용되고 있으나, 갑자기 폭설이 내리는 경우는 염화칼슘 또는 모래를 도로에 직접 살포해야 하므로 신속한 융설 작업이 불가능하게 되며 많은 시간과 인원 장비를 필요로 하게 된다. 또한, 염화칼슘은 살포 후에 지속적으로 눈이 내리면 염화칼슘의 농도가 낮아져 결국에는 다시 결빙되는 문제점이 있으므로 이러한 방법은 눈길 또는 빙판길의 미끄럼 사고를 근본적으로 해결할 수 없다.In addition, in the non-slip section constructed with a non-slip packaging material or acrylic copolymer resin as a non-slip agent in the prior art, snow is accumulated or frozen, causing the vehicle to be a sliding accident, which is a major factor in winter traffic accidents. As such, in order to prevent snow accumulation or freezing, a method of spraying sand or calcium chloride on the road is currently used. However, in case of sudden heavy snowfall, calcium chloride or sand must be sprayed directly on the road, so a rapid snow melting operation is required. It becomes impossible and requires a lot of time and personnel equipment. In addition, since calcium chloride has a problem of lowering the concentration of calcium chloride and eventually freezing again when snow falls continuously after the application, this method cannot fundamentally solve the sliding accident of snow road or ice road.
본 발명은 상기와 같은 문제점들을 해결하기 위하여 도출된 것으로서, 첨가되는 결빙 방지제가 높은 융설 기능을 유지할 수 있어 눈길 미끄럼 사고 및 도로 시설물의 열화를 방지할 수 있는 도로 포장용 결빙방지 표면처리 조성물 및 이를 이용한 도로 포장 결빙방지 표면 처리 방법을 제시하는 것을 그 목적으로 한다.The present invention was derived to solve the above problems, the anti-freezing agent to be added is able to maintain a high snow melting function to prevent snow skid accidents and deterioration of road facilities and road surface antifreeze surface treatment composition using the same The purpose of the present invention is to propose a method for treating road pavement preventing ice.
