겨울이 되면 도로에 결빙(블랙아이스)이 발생하여 인명피해와 재산피해를 유발한다. 이를 방지하기 위해 도로 상면에 염화칼슘을 살포하여 결빙을 제거하고 있지만 염화칼슘에 의해 차량 부식이 발생되고, 콘크리트 도로가 열화되는 등의 문제가 발생한다.In winter, ice (black ice) forms on roads, causing casualties and property damage. To prevent this, calcium chloride is sprayed on the top of the road to remove ice, but problems such as vehicle corrosion and concrete road deterioration occur due to calcium chloride.
