The paper has studied on how to quantitatively evaluate greenhouse gas emissions during asphalt pavement construction. The calculation method is put forward, and the greenhouse gas emissions during the construction of asphalt pavement are obtained. Through calculating examples, the paper got energy saving and emissions reduction effect of warm mix asphalt, at the same time, and drew conclusions of effects of different mixing equipment and transportation equipment on total greenhouse gas emissions. The paper got some good conclusions through the calculation data: the raw material production process accounts for 13% of the total emissions; while asphalt mixture mixing, paving and rolling accounted for 67% of the total emissions, of which about 60% were in the asphalt mixture mixing stage alone. Transport processes account for 20% of total emissions. Compared with warm mix asphalt, heat mix asphalt reduced emissions by 18.2%. The main influencing factor of greenhouse gas emissions in the transportation process is the ratio between diesel consumption of transport equipment in one hundred kilometers and the maximum freight volume of the transportation equipment.
