Embodiment 1
[0024] After heating and melting, C1 was added to the base asphalt J1 in the melting and stirring at a weight ratio of 3% (the modifier accounted for the weight percentage of the modified asphalt) and mixed evenly at 180°C. The test results are shown in Table 3.
Embodiment 2
[0026] After heating and melting, C2 was added to the base asphalt J1 in the melting and stirring at a weight ratio of 7% (the modifier accounted for the weight percentage of the modified asphalt) and mixed evenly at 200°C. The test results are shown in Table 3.
Embodiment 3
[0028] After heating and melting, C3 was added to the base asphalt J2 in the melting and stirring at a weight ratio of 20% (the modifier accounted for the weight percentage of the modified asphalt) and mixed evenly at 220°C. The test results are shown in Table 3.
