Selection method for environmental equipment combination for paving work

Against the background of accelerating global warming due to the effect of greenhouse gases, efforts to reduce greenhouse gas emissions are being made worldwide. Among public works, road construction, which involves numerous processes, leads to greenhouse gas emission. Although many studies have been conducted on earth work in road construction few studies on have dealt with paving work. The purpose of this study is to propose an optimum equipment combination selection method that simultaneously considers the construction cost, construction period, and environmental load of paving equipment used for paving construction. Standards of estimate and price information were used to estimate the construction cost and period, and a LCI database was used to estimate environmental load. The result showed that construction period and cost were proportionally interrelated, but the environmental load was inversely proportional. Accordingly, the optimum area was established for which the numerical values of the construction period and cost and environmental load can appropriately be considered. It is expected that the proposed selection method for paving work equipment combination will be helpful in selecting combinations that can consider both economic feasibility and the environmental effect.
