신재 표층용 가열 아스팔트 콘크리트와 재생 표층용 가열 아스팔트 콘크리트의 LCCO₂ 비교분석

Asphalt concrete is a composite material commonly used to surface roads, parking lots, and airports. Currently recycled asphalt concrete is used increasingly for global environmental protection in our society. So, this study is intended to measure and compare life cycle CO₂(LCCO₂) on both virgin asphalt concrete and recycled one in accordance with ISO 14044:2006. As a result, LCCO₂ emissions generated by recycle asphalt concrete is 67.7% higher than virgin asphalt concrete because a lot of energy consumption is needed in the drying process of recycled aggregate production.
