- •
A 7% ground tire rubber (−40 mesh) incorporated with other modifiers/acid was mixed to produce PG 76 binders.
- •
Twenty-three binders from three base binders and five polymers or acid were used in this paper.
- •
Viscosity, fail temperature, G∗/sin δ, phase angle, amplitude and frequency sweep, and creep recovery were evaluated.
- •
Rheology properties of modified binders are dependent on polymer type and asphalt source.
