Estimating Carbon Reductions of Green Highway Technologies

Jongdae Baek, Hyejung Hu, Guenhee Lee, and Geonho Kim
Abstract—There are great activities around developing and applying new green highway technologies to reduce carbon emissions around the world. This study introduces three green highway technologies related to road construction materials and method that are among many other technologies developed by the Carbon Neutral Road Technologies Research Group in Korea. They are (technology A) manufacture and construction of carbon-absorbing road facilities utilizing activated industrial by-products, (technology B) low carbon non-cement soil pavement utilizing industrial by-products and inorganic binder, (technology C) low carbon soil pavement utilizing polymer concrete. Comparative carbon reduction by the three technologies calculated via G-TIES (Green Highway Technology Investment Evaluation System) developed by the research group to evaluate investment benefits of green highway technologies is also included in the study. When technology A are applied to construction and operation of curbs in 1 km road section, it can reduce 2.69 tCO2 in the construction stage and 24.75 tCO2 in the operation stage to reach 27.44 tCO2 in total carbon emissions compared to the existing technology when assuming road operation for 30 years. When technology B and C are applied to 1 km road pavement construction, 598 tCO2 and 404.97 tCO2, respectively, will be reduced. Green technologies outlined in this paper, actual reduction of carbon emissions and methodologies used to calculate reduction will hopefully serve as a good reference to researchers and technology developers.

Index Terms—Carbon emissions, low carbon, green highway technology, evaluation system.
