Abstract: The characteristics of deformation recovery of asphalt binder in medium to high temperature conditions affect the rutting resistance of asphalt mixture directly. The traditional empirical indexes (i. e., penetration, softening point, etc.) and certain mechanical performance indexes based on complex modulus have apparent drawbacks in characterizing the delayed strain recovery properties of asphalt. This work proposed a characterization method using the slope of phase angle curves in frequency domain based on the difference of mechanical behavior described by series Maxwell model and parallel Kelvin model and the frequency response characteristics of viscoelastic mechanical parameters. This study comprehensively analyzed the complex moduli and phase angles of three penetration levels of base asphalt and two types of SBS modified asphalt at 30—70 ℃. It was found that the difference in viscoelastic properties of the different types of asphalt binders can be reflected by the master curve of phase angle in frequency domain more clearly than the master curve of complex modulus. The experiment results showed that the phase angle of SBS modified asphalt presents an increase trend in specific temperature and frequency domains, rather than the monotonically decrease trend with the increase of phase angle presented by the base asphalt. This rule can be used to characterize the delayed strain recovery characte-ristics of asphalt binder and to evaluate the rutting resistance of the material in a specific temperature range.
