Abstract EN
Sasobit additives with different dosages were added into 70# and 90# virgin asphalt binders to prepare WMA binders.
The rheological properties, including G∗ and δ, were measured by using DSR at the temperature ranging from 46°C to 70°C, and the effects of temperature, additive dosage and aging on G∗/sinδ, critical temperature, and H-T PG were investigated.
The results indicate that WMA additive improves G∗ but reduces δ, and the improvement on 70# virgin binder is more significant.
G∗/sinδ exponentially decreases with the increasing temperature but linearly increases with the increasing additive dosage.
Aging effect weakens the interaction between binder and additive but significantly increases the binder’s viscosity; that is why G∗/sinδ is higher after short-term aging.
In addition, the critical temperature increases with the increasing additive dosage, and the additive dosage should be more than 3% and 5% to improve H-T PG by one grade for 70# and 90# virgin binder, respectively.
