摘要
将表面修饰后的氧化石墨烯(N-GO)添加到SBS改性沥青中,对比测试了不同掺量N-GO对SBS改性沥青高温储存稳定性、老化前后三大指标以及相应混合料的高温稳定性、低温抗裂性以及抗水损等方面指标的影响情况。结果表明,二维纳米材料氧化石墨烯能够有效阻止SBS改性沥青高温离析、改善其抗老化性能,相应改性沥青混合料的高温稳定性、低温抗裂性以及抗水损性能有明显提升,且在测试范围内,N-GO掺量越高,效果越显著。
In this paper,graphene oxide(N-GO)with surface modification was added to SBS modified asphalt,the effects of different content of N-GO on the high temperature storage stability and three major indicators before and after aging of SBS modified asphalt,and high temperature stability,low temperature cracking resistance and water loss resistance of the corresponding mixture were compared and tested.The results showed that the graphene oxide,a two-dimensional nanomaterial,can effectively prevent SBS modified asphalt from high temperature segregation and improve its aging resistance,and the high temperature stability,low temperature cracking resistance and water loss resistance of the corresponding modified asphalt mixture have been significantly improved.Moreover,within the test range,the higher the N-GO content,the more significant the effect.
