In order to investigate the high temperature rheological properties of warm mix asphalt, Evotherm3G and EC120 were added into the matrix and SBS modified asphalt to prepare the samples. Dynamic shear rheological(DSR) test and multi stress creep recovery(MSCR) test were used to evaluate the high temperature rheological properties of warm mix asphalt before and after short term aging. The results show that Evotherm3G increases the phase angle of asphalt, reduces the complex modulus and rutting factor, while EC120 reduces the phase angle of asphalt and increases the complex modulus and rutting factor of modified asphalt.Evotherm3G increases the strain of asphalt, reduces the creep recovery rate of asphalt, and improves the non recoverable creep compliance of asphalt. EC120 reduces the strain of asphalt, improves the creep recovery rate of asphalt and reduces the non recoverable creep compliance of asphalt. Through grey correlation analysis, the grey correlation degree between non recoverable creep compliance and rutting factor is 0995, which can reflect the high temperature performance of asphalt to a certain degree.
