Characterisation of complex polymer modified bitumen with rheological parameters

The use of modifiers for bituminous binders has become common practice to enhance the performances asphalt materials. As a result, binder becomes more complex, with various phase morphologies. Conventional testing methods may not always be suitable. example, European standardisation committee is looking at different ways characterise Polymer modified Bitumen. RILEM Technical Committee 272-PIM ‘Phase and Interphase behaviour innovative Materials’, its Task Group TG1, evaluating test complex binders. aim evaluate how these tests could address An inter-laboratory programme was conducted 17 laboratories. Seven were evaluated; two neat bitumen PmB. In addition conventional property measurements, an extensive effort made on investigating rheological parameters obtained from Dynamic Shear Rheometer measurements. Some initial results are presented discussed in view future revision product standard EN 14023
