Abstract

A plan was prepared to measure the amount of electricity and fuel used when producing an asphalt mixture in an asphalt plant. And the amount used in the asphalt plant was measured and the carbon dioxide emission was analyzed using this. As a result, the carbon dioxide emission was 7.7 kgCO2eq/ton for the new asphalt mixture and 10.2 kgCO2eq/ton for the recycled asphalt mixture, which was 1.3 times higher for the recycled asphalt mixture. The emissions from burner fuel use were 3.5 times higher for new asphalt mixtures and 5.6 times higher for recycled asphalt mixtures than for carbon dioxide mixtures according to electricity use. Since electricity consumption is greatly affected not only by production time but also by the time between production operations, it is necessary to increase continuous production time. The carbon emission generated when producing domestic asphalt mixtures applying the research results is 164,454 tCO2eq/year, and it was analyzed that it has an effect of KRW 1.73 billion/year when converted into emission trading prices.
