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