This study evaluates environmental impact factor emissions generated by three concrete-pavement methods. Specifically, internationally commercialized programs are used to calculate the environmental impact factors of selected domestic concrete-pavement projects, thereby identifying areas requiring improvement. This study quantified the material usage and energy consumption associated with the construction and maintenance of three concrete-pavement methods. Using internationally commercialized software, this study evaluated the emissions of environmental impact factors for jointed concrete, continuously reinforced concrete, and mechanized continuously reinforced concrete pavements under three assumed maintenance scenarios for each method. Analysis of the environmental impact factors over a 30-year period under three maintenance scenarios (Cases A, B, and C) shows that, for the three pavement methods, the construction phase is dominant— constituting 70%–99%—across most impact categories, including global warming, smog formation, acidification, eutrophication, human toxicity, ecological toxicity, and respiratory effects. This study analyzes the environmental impact factors during the construction and maintenance processes of three concrete-pavement types using foreign LCI databases and identifies the environmental impacts of each input material. In the future, if LCI and LCIA databases for domestic road pavement materials are established and analyses are conducted based on the conditions presented in this study, then a foundation can be realized for the development of environmentally friendly materials and methods.
