Abstract

Physicochemical characterization of bitumen and polymer modified bitumen has been a research subject for the last decades. Various microscopic and spectroscopic techniques have been used to unravel the bitumen microstructure and to establish the link to its chemical composition. Over the years, the usage of bitumen has risen. This is particularly true for polymer modified bitumen (PmB) which has primarily been blended with styrene-butadiene-styrene (SBS) polymers. Since there is a demand for homogeneous blending and an overall quality control, suitable methods need to be developed. Fluorescence spectroscopy and fluorescence microscopy were found useful tools to achieve these goals. This paper focuses on the analysis of a 160/220 pen-graded base bitumen and SBS modified bitumen. Complementary analysis of specific surfaces enables a better understanding of chemical composition (spectroscopic information) and microstructure (microscopy).
