Rheological properties of Styrene-Butadiene-Styrene (SBS)-Asphalt composites were studied as a function of the SBS concentration, frequency, and temperature. The experimental data were fitted by using the percolation model, aiming to predict the rheological behavior of this composite at any specific composition, temperature, and frequency. This was achieved through a WLF-type relationship that has been extended to allow composition to be considered. This extended WLF is conceptually supported by a free volume theory, allowing to generate master curves with shifts in temperature (Log aT) and in concentration (Log aC). The temperature-concentration displacements (Log aTC) and the concentration-temperature displacements (Log aCT) were well fitted, producing practically the same super-master curve, demonstrating that this model applies well to both types of shifts. |
