Abstract: Provided are a low carbon additive for a warm-mix asphalt (WMA) mixture, in which vegetable wax based on modified palm wax is mixed into polyethylene wax so as to be able to promote high-temperature physical properties of the WMA mixture as well as solve problems on low-temperature physical properties of the WMA mixture, warm-mix asphalt produced using the same, and a method of producing the WMA mixture using the using the warm-mix asphalt. The low carbon additive contains polyethylene wax and vegetable wax at a weight ratio of 20:1 to 1:2. The modified palm wax employs palm wax that melt-reacts with sodium hydroxide (NaOH) and stearic acid (CH3(CH2)16COOH). This low carbon additive enables the WMA mixture to be efficiently produced, and thus makes it possible to reduce heating energy required when the WMA mixture is produced. Thereby, it is possible to remarkably reduce the emission of carbon dioxide that is a principal factor of global warming.
