Embodiment 1
[0028] The first step, take the polyethylene glycol that is 4.2% by mass, the activated carbon that is 0.9% by mass, the plastic that is 0.9% by mass, the sulfur that is 0.3% by mass, the sulfur that is 93.7% by mass % bitumen, the mass sum of the above substances is 100%;
[0029] The second step is to prepare the modifier
[0030] Heat the polyethylene glycol at a constant temperature of 160°C until it melts, then gradually increase the temperature to 200°C and keep it, then add plastic to the molten polyethylene glycol until the plastic is completely melted in it. After the polyethylene glycol and the plastic are stirred uniformly, activated carbon is added therein, and the modifier is stirred evenly again to obtain a modifier, and then the modifier is cooled and left at room temperature for 20 hours to obtain a solid modifier;
[0031] The third step is to crush the modifier
[0032] The solid modifier obtained in the second step is put into a pulverizer and pulverized u...
Embodiment 2
[0036] The first step, take the polyethylene glycol that is 7% by mass, the activated carbon that is 1.5% by mass, the plastic that is 1.5% by mass, the sulfur that is 0.5% by mass, the 89.5% by mass % bitumen, the mass sum of the above substances is 100%;
[0037] The second step is to prepare the modifier
[0038] Heat the polyethylene glycol at a constant temperature of 170°C until it melts, then gradually increase the temperature to 210°C, and keep it, then add plastic to the molten polyethylene glycol until the plastic is completely melted in it, and the above-mentioned molten After polyethylene glycol and plastics are stirred evenly, activated carbon is added therein, and stirred evenly again to obtain a modifier, and then the modifier is cooled and left at room temperature for 28 hours to obtain a solid modifier;
[0039] The third step is to crush the modifier
[0040] Put the solid modifier obtained in the second step into a pulverizer and pulverize until the partic...
Embodiment 3
[0044] The first step, take the polyethylene glycol that is 5% by mass, the activated carbon that is 0.9% by mass, the plastic that is 1.2% by mass, the sulfur that is 0.4% by mass, the 92.5% by mass % bitumen, the mass sum of the above substances is 100%;
[0045] The second step is to prepare the modifier
[0046] Heat the polyethylene glycol at a constant temperature of 165°C until it melts, then gradually increase the temperature to 205°C and keep it, then add plastic to the molten polyethylene glycol until the plastic is completely melted in it, and the above-mentioned molten After the polyethylene glycol and the plastic are stirred evenly, activated carbon is added therein, and the modifier is stirred evenly again to obtain a modifier, and then the modifier is cooled and left at room temperature for 24 hours to obtain a solid modifier;
[0047] The third step is to crush the modifier
[0048] Put the solid modifier obtained in the second step into a pulverizer and pulv...
