In this paper the influence of short and long term ageing processes on polymer dispersion in the polymer modified bitumen has been analyzed. The bitumen was modified by various amounts of SBS elastomers. Microstructural changes of polymer dispersion were tested using fluorescent microscopy. It has been shown that the phase separation of SBS modified binders is influenced by the base bitumen and the characteristics and content of the polymer. Correlations were sought between viscoelastic properties and microstructure after ageing. The results showed that it is essential to describe the microstructure of the polymer modified bitumen, especially the description phases, shapes and proportion of dispersed parts.
