These waste tires are made of elastic rubber material to exert cushioning function against sudden impact loads to relieve the impact force applied when the car collides, and also to collect easily without incurring high costs in the surroundings. It is known to have the advantage of being able to install in, such as to reduce the installation cost.
그러나, 이와 같이 보호수단으로 사용되는 폐타이어는 다음과 같은 문제점을 수반하게 되었다. 첫째 폐타이어는 자동차가 느린 속도로 충돌할 때에는 쿠션기능을 발휘하여서 어느 정도 안전성을 보장하여 주는 것이 사실이나, 자동차가 빠른 속도로 충돌하는 경우에는 커다란 충격력을 감당하지 못하여 도로의 구조물과 자동차가 크게 파손될 뿐만 아니라, 자동차 내의 탑승자가 부상을 입거나 심한 경우에는 사망하게 되는 등의 문제점이 있었으며, 둘째 폐타이어는 종류별로 크기와 형태가 다양하여 도로의 구조물에 맞추어 균일하게 설치하기 어려울 뿐만 아니라, 설치상태가 매우 조잡하여서 외적인 미관을 크게 저하시키는 등의 문제점을 야기케되었다.However, the waste tires used as a protection means come with the following problems. First, it is true that the waste tires provide a certain level of safety by cushioning when the car collides at a slow speed, but when the car collides at a high speed, the structure of the road and the car are greatly reduced. Not only are they damaged, but the occupants in the car are injured or killed in severe cases. Second, the tires are not only uniform in size and shape, but also difficult to install uniformly according to the structure of the road. The condition was so crude that problems such as greatly deteriorating external aesthetics were caused.
