Abstract
Modi ed bitumen enhances the performance properties of asphalt mixtures.
A number of studies in the last decade have evaluated the performance properties of
modi ed binders at di erent service temperatures. It is however possible to evaluate
some modi ed binder time-temperature characteristics and performance properties through
their rheological master curves. In this research, styrene butadiene styrene, ethylene vinyl
acetate, polyphosphoric acid and crumb rubber were used to modify a PG58-22 base binder.
Rheological master curves for jGj and phase angles of these binders were generated using
data from the dynamic shear rheometer and bending beam rheometer at temperatures
ranging from ??30C to about 88C. The rheological interpretation of the results indicated
improved high and low temperature properties and reduced temperature susceptibility for
most of the modi ed binders. A comparison of the modi ed binders was done based on the
visual inspection of master curves for di erent temperature ranges.
