Abstract: The research described in this paper forms part of an attempt to relate properties of components and sub-systems in asphalt mixes to overall performance of the mix. Some rheological properties of the bitumen and bitumen/filler system are reported here as sub-systems of the mix. The results of a test programme are presented for the rheological characterisation of bitumen-rubber and SBS modified bitumen compared to standard bitumen. The effect of filler addition was also investigated. The three binders in this research were: 60/70 penetration grade bitumen, SBS modified 60/70 bitumen, crumb-rubber Bitumen. The filler/bitumen ratio in all cases was 1,1 by mass.The conclusions that could be drawn based on the results of this study include: linear limits of binder/filler sytems are low; Bitumen-Rubber and SBS binders show up very different from 60/70 bitumen in the Black Diagram; Viscosity properties at mixing and compaction temperature of SBS modified binders differs from normal penetration grade bitumen.
