PURPOSE: A medium-temperature asphalt concrete composition is provided to form asphalt concrete at low temperature by adding asphalt styrene-butadiene-styrene(SBS). CONSTITUTION: A medium-temperature asphalt concrete is formed by mixing 8-95 weight% of aggregate, 3-18 weight% of an asphalt concrete binder, and 1-4 weight% of medium-temperature asphalt concrete modifier containing SBS. The medium-temperature asphalt concrete modifier contains 45-55 weight% of SBS, the modular weight of which is between 50,000 and 100,000, 1-8 weight% of processing oil, 5-15 weight% of a petroleum resin, 0.1-0.5 weight% of antioxidant, and 25-35 weight% of sasobit wax.
