摘要
In one embodiment of the present invention, an embodiment of the present invention is a method for producing a styrene-butadiene-styrene block copolymer, comprising: 100 parts by weight of a low temperature reinforcing agent represented by the following formula (1): 50 to 100 parts by weight of a styrene- And 30 to 70 parts by weight of a viscosity reducing agent selected from a polyethylene glycol nonionic surfactant, a process for preparing the same, and a process for producing a mesophilic modified asphalt and a mesophilic modified asphalt mixture containing the modified mesophilic modified asphalt mixture. According to the present invention, it is possible to put the intermediate tempered modified asphalt into the asphalt production facility at room temperature without any additional treatment such as heating because it has fluidity at room temperature when preparing the pre-mixed type modified asphalt, and the mixing speed with the asphalt is improved, The phase separation does not occur and the high temperature property and the low temperature property of the asphalt can be improved at the same time, and the construction can be performed at a temperature lower than that of the general asphalt.
