摘要
探讨了纳米石墨对沥青三大指标的影响。随着纳米石墨掺量的增加,沥青的针入度和延度降低,针入度指数和软化点增大。说明纳米石墨对沥青的高温性能有一定改善作用,对低温性能有不良影响,改性沥青的温度敏感性降低。
The effect ofnano graphite on the three indices of asphalt.Was investigated, With the increase of graphite content, penetration and ductility is decreased, penetration index and softening point is increased. High temperature performance of asphalt nano graphite improved to a certain extent, has a bad effect on the low temperature performance, reduce the temperature sensitivity of modified asphalt.
