AB Road bituminous binders are becoming more complex since, to enhance properties and/or engineer circulareconomy, the conventional binder is enriched with modifiers of different nature giving birth to a final-productrecognisable as highly heterogeneous fluid. The assessment of these materials relies on rheological measurements;however, existing testing equipment are designed for homogeneous fluids, proving to be often inadequate.In fact, rotational testing lacking mixing efficiency during measurements, can compromise sample stability,resulting in non-representative results Lo Presti et al. (2014). To address these challenges, a dual helical ribbons(DHR) was purposefully created and successfully employed in prior studies to measure the rotational viscosity ofhighly heterogeneous asphalt materials Giancontieri et al. (2019). While the DHR effectiveness has beenextensively discussed in earlier investigations, this study aims to contribute to the scientific community at largeby providing: state-of-the-art on improving mixing efficiency of highly heterogeneous fluids, rationalizing thechoice of the DHR geometry comprehensive technical details for realising any DHR, verified through numericalmodelling Calibration with model input parameters achieved by adopting the Rieger and Novak method, andfinally design validation. The authors aim for the broader material science community to benefit from thisinvestigation, enabling technologists to independently develop DHR devices and explore new applications.
