摘　　要：为分析用DSC吸热峰的何种特征值来表征沥青的感温性能,对DSC吸热峰能量值、峰宽度值、峰值温度和针入度指数、针入度粘度指数的相关性进行分析,得出结论:DSC吸热峰能量值和峰宽度值与针入度指数和针入度粘度指数都具有良好的相关性,吸热峰能量值和峰宽度值可以用来表征沥青的温度敏感性。In order to analyze which eigenvalues of DSC endothermic peak are used to represent temperature susceptibility performance of asphalt, this paper analyzes the independence between energy values, peak width values, peak temperature, needle penetration indices and needle penetration viscosity indices of DSC endothermic peak, and draws conclusions that perfect independence is exhibited between energy values, peak width values and needle penetration indices, needle penetration viscosity indices of DSC endothermic peak, and energy values and peak width values of endothermic peak can be used to represent temperature susceptibility of asphalt.
