03. Asphalt Works

 

Asphalt paving works is a composite material commonly used to surface roads, parking lots, airports and other such places. It lays the asphalt flat and provides minor compaction before it is compacted by a roller.

아스팔트 공사하는 모습을 운전하시면서 종종 보셨을 거예요. 많은 건설장비가 투입되어 장비사고 위험이 높습니다. 사용 중인 도로라면 교통사고 위험은 더욱 높아지죠.

2019년에 아스팔트를 싣고 와서 트랙터에 쏟아주는 과정에서 덤프트럭이 전도되는 사고가 있었습니다. 다친 사람은 없었으나 덤프트럭은 주요 부붐 및 거더가 손상되는 사고 였습니다. 원인은 아래와 같이 운전자 미숙함이었는데요. 운전원이 아스팔트 재료 상태를 모래와 같이 인식하여 트랙터에 쏟아붙는 속도를 과감하게 진행했습니다. 

트랙터의 아스팔트가 소모되지 않는 상태에서 덤프트럭의 짐칸을 너무 높이 올려 차량이 편중되어 전도되었습니다. 전도된 덤프트럭을 일으키는데도 상당한 시간을 소모했죠. 

무엇보다 건설장비 주변에는 가까이 하지 마시구요. 일상생활에서는 공사현장 EGI 휀스에 기대거나 오래 머물러 있지 않으시길 바랍니다. 최근 발생한 광주에서 건축물 해체 작업 중 붕괴되는 사고, 청량리 역사 공사 작업 중 휀스 밖으로 건설장비 전도 사고 등이 안타깝게도 일어 났었습니다. 공사현장은 주의해서 빨리 지나가세요. 타워크래인이 현장 밖으로 나와 회전반경을 운전하는 것도 불법입니다.
