摘要

The pavement technologies that reduce the CO_2 emission are thought that consisted of the technologies of WMA, cold mixasphalt, recycling technologies, long-life pavement. Of these, the effects of reducing CO_2 emissions had beenassessed for the technologies of WMA, and the recycling technologies that include the in-plant pavementrecycling methods and the in-situ recycling methods.In this study, the reducing life-cycle CO_2 emissions of long-life pavement (composite pavement), extended-lifetechnologies (micro surfacing, chip seal, crack seal) were confirmed. Consequently, composite pavement can reduce the CO_2approximately 16% after 60 years from construction compared to concrete pavement, while it has a lot of CO_2 when it isconstructed first time. The asphalt pavement that adapted the extended-life technologies, WMA, RAP, in-situ recycling wereestimated that can reduce CO_2 emissions approximately 27% compared to cut-and-overlay methods.
