Abstract:
The rheological properties including the complex modulus G* and the phase angle δ of matrix and warm mix asphalt(WMA)binders were measured by using the dynamic shear rheometer(DSR)test at the medium temperature ranging from 16 to 40 ℃, and the relationships between the fatigue factor G*sinδ and the matrix binder property, WMA additive and test temperature were established. It is found that G* decreases with the increasing temperature while δ increases inversely, and G* of the asphalt binder with high WMA additive dosage is large, and δ is small. G*sinδ exponentially decreases with the increasing temperature and linearly increases with the increase in additive dosage, and the amplitudes of variation are large at low temperatures and high additive dosages. The effect of WMA additive on the rheological property is more remarkable for the matrix asphalt binder with low G*. Besides, aging has a great effect on the property of matrix asphalt binder, and a slight effect on the interaction between asphalt and additive. The high additive dosage can increase the fatigue cracking potential of the asphalt binder.
