| Abstract: | 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. |
