Özet
In this study, halloysite and sepiolite nanoclays were used to reinforce SBS modified
bitumens. The nanoclays used are different from the materials in the literature and have
properties such as easy to find, economical and available from local sources. The mixing
parameters were determined before production process. The polymer additive SBS was
added into base bitumen at 3% and 5%, while the nanoclay additives were added into polymer
modified bitumen at 2% and 4% ratios. The morphological structures were investigated under
fluorescence microscope. Physical and rheological properties of the samples were compared.
The phase separation cases were investigated by storage stability test. Furthermore, rutting
performance of samples was measured with zero shear viscosity (ZSV) and multi stress creep
recovery (MSCR) test methods.
