| 摘要: |
| [目的]探寻5U北美岩沥青的微观性能,为实际应用提供科学依据。[方法]利用E-M-D法,分析东莞东交70号沥青、东莞东交70号沥青+12% 5U北美岩沥青(Ⅰ)、东莞东交70号沥青+15% 5U北美岩沥青(Ⅱ)、东莞东交70号沥青+18% 5U北美岩沥青(Ⅲ)的特征官能团。[结果]东莞东交70号沥青的芳碳率最低,而且随着5U北美岩沥青含量的增加,芳碳率逐渐上升。东莞东交70号沥青摩尔比(H/C)最大,其次是东莞东交70号沥青+12% 5U北美岩沥青。[结论]随着5U北美岩沥青掺量的提高,沥青改性后的高温稳定性能提高;降低温度敏感性,对沥青耐低温性能无改善作用。 |

| Abstract: |
| [Objective] The microscopic properties of 5U North American rock asphalt was explored in order to provide scientific basis for practical application.[Methods] The E-M-D method was used to analyze the characteristic functional groups of Dongguan Dongjiao -70 asphalt, Dongguan Dongjiao-70 asphalt +12% 5U North American rock asphalt (Ⅰ), Dongguan Dongjiao-70 asphalt +15% 5U North American rock asphalt (Ⅱ) and Dongguan Dongjiao-70 asphalt +18% 5U North American rock asphalt (Ⅲ).[Results] Aromatic carbon rate was the lowest in Dongguan Dongjiao -70 asphalt, and increased gradually with the augmentation of rock asphalt content.The H/C molar ratio of Dongguan Dongjiao-70 asphalt was the largest, followed by that of Dongguan Dongjiao-70+12% 5U North American rock asphalt.[Conclusion] With the increase in the content of 5U North American rock asphalt, the high temperature stability of modified asphalt was improved, and the temperature sensitivity was reduced, but the low temperature resistant was not improved. |
