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.
