Estimation of the CO2 emissions in producing HMA and WMA in Japan

In general, pavement repair works in Japan, which consist of material production, transportation, construction and disposal, CO2 emissions during the material production account for about 60% of the total emissions from the whole stages. In addition, about 60% of the emissions during production occurs during the preparation of hot asphalt mixture. Therefore, reducing emissions during this stage should effectively reduce the CO2 emissions from paving works. In this study, CO2 emissions during the preparation of hot mix asphalt were investigated by interviewing asphalt plants in Japan and determining the fuel consumptions. The amount of CO2 emitted for producing warm mix asphalt additives was also estimated to clarify the effects of warm mix asphalt technologies on reducing CO2 emissions. The study showed that warm mix asphalt technologies reduce CO2 emissions by about 10%, even taking the emissions from the production of additives into account.
