In this study, the environm ental impact evaluation for CO2, NOx, SOx and particulate matter emissions was performed based on repair examples of highway bridges. It was shown that the amount of CO2 emission derived from constituent materials, execution and transportation accounts for 40 to 60%, 40 to 60 % and about 5%, respectively, which is different from newly constructed structures. Within this study, in the integrated life-cycle evaluation of the above 4 environmental impact factors, it was found that the environmental impact for repair using pr ecast concrete slabs is smaller than that using reinforced concrete slabs. It was also shown that about 23% of CO2 emission, about 7% of NOx emission, about 39% of SOx emission and about 20% of particulate matter emission can be reduced when a type of binding material and a curing method are changed as a measure for reducing the environmental impact for repair using precast concrete slabs.
