%X 为了研究不同产量的氧化石墨烯对SBR改性沥青的影响&#65292;制备氧化石墨烯/SBR复合改性沥青&#65292;采用三大指标试验进行氧化石墨烯/SBR复合改性沥青的常规性能测试&#65292;并利用动态剪切流变仪(DSR)和弯曲蠕变试验(BBR)分析复合改性沥青的基本性能、高温流变性能和低温抗裂性能。试验结果表明&#65306;一定掺量的氧化石墨烯可以提高SBR改性沥青的基本性能&#65307;剪切模量、相位角和抗车辙因子随着氧化石墨烯的掺量增加&#65292;呈现先增加后减小的趋势&#65292;说明氧化石墨烯可以提高SBR的高温流变性能&#65292;但是氧化石墨烯的掺量不能过多&#65307;增强了抗车辙能力和高温性能&#65292;还可以提高其低温抗开裂性能。<br>In order to study the effect of different yields of graphene oxide on SBR-modified asphalt and prepare graphene oxide/SBR composite modified asphalt, three major index tests were used for the conventional performance tests of graphene oxide/SBR composite modified asphalt, and Dynamic Shear Rheometer (DSR) and Bending Creep Test (BBR) were used to analyze the basic properties, high-temperature rheological properties, and low-temperature anti-cracking of composite modified asphalt performance. The test results show that a certain amount of graphene oxide can improve the basic performance of SBR modified asphalt; shear modulus, phase angle and rutting resistance factor with the increase in the dosage of graphene oxide showed a trend of increasing and then decreasing, which indicates that graphene oxide can improve the high-temperature rheological properties of SBR, but the dosage of graphene oxide can&#8217;t be too much; it can enhance rutting resistance and high-temperature performance, and also can improve its low-temperature crack resistance.
