Analysis of Construction-specific Environmental Load Characteristics in the Road Paving Work Maintenance & Management Phase

Abstract

In accordance with the Paris Agreement that was signed to cope with recent climate change, the Republic of Korea has presented its greenhouse gas reduction goal as 37% compared to BAU. Accordingly, construction industry that occupies 40% of total industrial energy consumption also needs to make efforts to reduce greenhouse gas. In particular, studies are needed on the effort to reduce emission amount of environmental pollutants that occur during road constructions. In the case of road construction project, which is the subject of this study, large amounts of environmental pollutants are discharged during not only construction process but also operation and maintenance & management process. For analyzing the characteristics of environmental load occurring during the road maintenance & management phase, this study conducted life cycle assessment (LCA) for 10 cases of maintenance & repair projects for local roads that have been constructed in Korea to analyze environmental load characteristics according to construction types. As for the distribution of weighted values, TET and GW showed significant results with respectively 42.45% and 27.65%, followed by ARD (13.67%) and HT (11.00%).
