Abstract
Disclosed is a modified asphalt composition including a styrenic block copolymer and a vegetable wax as modifier. With lower viscosity at high temperatures as compared to the asphalt composition modified only with the styrenic block copolymer, it can be manufactured and used at lower temperatures. Also, with higher ductility at low temperatures, it can minimize fatigue crack even in cold weathers.
