| 摘要: |
| 利用天然岩沥青作改性剂,对AH-70基质沥青进行改性,获得了良好的试验效果.经天然岩沥青改性后的沥青其高温性能大为提高,感温性得到改善,抗老化能力和稳定性有所加强;在理论上对天然岩沥青改性机制及其对沥青性能的影响模式进行了定性分析,以利于天然岩沥青改性沥青的进一步研究和生产应用. |

| Abstract: |
| Modified asphalt was successfully prepared based on AH-70 bitumen with native rock asphalt modifier,and favorable performance was obtained.Native rock asphalt dramatically upgraded its high-temperature performance,improved its thermal susceptibility,and fortified its resistance to aging.In theory,modification mechanism and effect mode were discussed in universality. |
| Key words: rock asphalt,modified asphalt,high-temperature performance,thermal susceptibility |
