Abstract

The global community demands the reduction of environmental pollution such as greenhouse gas and carbon dioxide emissions. According to these requirements, the road construction project in the highest energy consuming industry is required the efficient way of reducing environmental pollution emissions. In this study, during the whole life cycle process, an environment impact assessment was performed for the several road construction projects in order to evaluate environmental stress through the road construction process. This study provides a proper process of environment impact assessment for life cycle assessment (LCA) analysis of road construction project, and figures the environmental stress regarding to the major construction materials for the case projects. In addition, this study conducted a sensitivity analysis for the key materials of environmental stress through the quantity analysis of major materials for the 1km section of a road construction. By this sensitivity analysis of total environmental stress change from the different volumes of constructing materials, it would be useful information for the environment impact assessment for the future road construction project.

최근의 국제사회는 경제성장에 따른 기상이변을 방지하고자 이산화탄소, 온실가스 등의 환경 오염물질 배출 저감을 요구하고 있다. 이러한 요구사항에 따라 에너지 다소비 산업 가운데 도로건설에 대한 효율적인 환경오염물질 배출 저감 방안이 요구된다. 본 논문에서는 전과정 영향평가의 절차에 적합한 도로건설공사 환경영향평가 프로세스를 제시하고, 이를 바탕으로 다수의 도로건설공사에 대하여 주요 건설자재의 환경부하량을 분석한 후, 1km 도로건설공사에서 발생하는 평균 환경부하량을 제시하고 있다. 주요자재수량에 대해서는 환경부하량에 대한 민감도 분석을 실시하였으며, 이러한 분석결과는 도로건설공사의 공법 및 자재별 수량 변화에 따른 전과정 환경영향평가에 유용하게 활용될 수 있을 것으로 판단된다.
