Embodiment Construction
[0038] A graphene-based high-performance modified asphalt, its innovation is: the high-performance modified asphalt is composed of 70# base asphalt, graphene and stearamide; the quality of 70# base asphalt, graphene and stearamide The proportioning relationship is: the quality of graphene is 20‰ of the quality of 70# matrix pitch, and the quality of stearamide is 1% of the quality of graphene.
[0039] Further, the specific surface area of the graphene is 300-400m 2 / g, the monolayer rate of graphene is greater than 80%, and the carbon content of graphene is greater than 98.9%.
[0040] A method for preparing high-performance modified asphalt, the innovation of which is that the method includes:
[0041] 1) adding trichlorethylene to stearamide until the stearamide is completely dissolved to obtain a mixed solution;
[0042] 2) In a closed state, the mixed solution was subjected to ultrasonic vibration treatment for 1.5 hours;
[0043] 3) Add the mixed solution into the 7...
