Effects of Various Modifiers on Rheological Property of Asphalt
The effects of different modifiers on rheological properties of asphalt were studies by dynamic shear tests. Seven kinds of asphalt binders were used to study the viscoelastic effects based on the hysteresis loop analysis from the following aspects: accumulation of deformation, elastic stored energy, viscous dissipative energy, viscoelastic ratio and complex modulus. Another two kinds of modified asphalts were used to verify the previous results and to describe performance of composite modified asphalt by conventional dynamic sweep tests. The results show that it is practicable and effective to use energy method to evaluate viscoelastic properties of asphalt; Aromatic oil can increase residual strain dramatically; Combination of rubber powder (or SBS) and aromatic oil can increase elastic stored energy greatly; Both rubber powder and SBS can increase viscoelastic ratio dramatically, followed by SBR; Composite modified asphalt has an excellent performance on road engineering.
