摘　　要：改性沥青广泛应用于高速公路沥青路面中,SBS改性沥青可同时改善沥青的高低温性能和感温性能,成为路面施工应用最主要的材料。利用衰减全反射傅里叶红外光谱法,从微观结构入手,建立了快速测定SBS改性沥青的方法,实现了改性沥青中SBS改性剂含量的快速定性及定量分析。该方法所用设备操作简单,轻便易于携带,通过某高速公路沥青质量快速检测服务进行了验证,可在施工现场对SBS改性沥青进行快速检测和评价分析,为工程决策提供参考。Modified asphalt is widely used in highway asphalt pavement,and SBS modified asphalt can simultaneously improve the high and low temperature performance and temperature sensitivity of asphalt,becoming the most important material for the pavement construction application.The method for determining the SBS modified asphalt rapidlyis established by using the attenuated total reflection Fourier transform infrared spectroscopy,and the rapid qualitative and quantitative analysis of SBS modifier content in modified asphalt is achieved starting from the microstructure.The equipment used in this method is simple to operate,lightweight and easy to carry.It is verified through a rapid asphalt quality testing service on an expressway,and can be used for rapid testing and evaluation analysis of SBS modified asphalt on the construction site,so as to provide reference for the engineering decision.
