Abstract:In order to study the dynamic properties and correlation of asphalt materials such as asphalt, asphalt mastic and asphalt mixture, the rheological test of asphalt and asphalt mastic was carried out by dynamic shear rheometer(DSR). The relationship of dynamic property between the asphalt and the asphalt mastic was analyzed, and the multivariate formula of complex modulus of asphalt mastic, complex modulus of asphalt and filler bitumen ratio had been established. Dynamic modulus test of five different types of asphalt mixtures was performed by asphalt mixture performance tester(AMPT). The relationship between the modulus and the phase angle of the asphalt material under the same frequency(or loading time) and temperature conditions was analyzed. It is found that the modulus and phase angle of asphalt mixture can be expressed by the modulus and phase angle of asphalt and asphalt mastic, and the relationship is independent of frequency(or loading time) and temperature. The relation expression of modulus and phase angle of asphalt, asphalt mastic and asphalt mixture is established.
