In order to explore the temperature sensitivity of different lignin modified asphalt, the temperature sensitivity evaluation method based on penetration test and dynamic shear rheological test was adopted. The asphalt samples with different lignin content before and after short-term aging were evaluated and analyzed. The results showed that the addition of lignin could effectively reduce the temperature sensitivity of bitumen, and the complex index method (CNI) was more effective in evaluating the temperature sensitivity of lignin modified asphalt. The main reason is that the addition of lignin increases the storage modulus (G′) of the asphalt , increases the elastic part of the asphalt; compared with the matrix asphalt short-term aging does not accelerate the aging process of the lignin modified asphalt. Rather, the physical process of further compatibilizing lignin with asphalt. It provides a reference for further study on the determination of preparation technology and evaluation of high temperature of lignin modified asphalt.
