The performance of cold bitumen emulsion (CBE) mixtures is strongly linked to an optimised design of the binder blends and mastics. Types and dosages of bitumen, mineral additions and the workability must be characterised and optimised. This study aims at providing an approach for the fundamental characterisation of CBE materials using rotational viscometry. Firstly, a procedure for measuring the viscosity of CBE slurries using the Brookfield viscometer was investigated by comparing results obtained by using a traditional spindle geometry and a novel impeller engineered to avoid phase separation: the dual helical ribbon (DHR). Afterwards, the effect of mineral additions and bitumen emulsions types was measured and modelled, also considering the influence of their concentration. The Krieger-Dougherty model proved to be a powerful tool to fit results and provide fundamental parameters for improved CBE materials engineering characterisation. Overall, the DHR was found a promising tool for CBE slurries rheological characterisation.

冷沥青乳液（CBE）混合物的性能与粘合剂混合物和胶泥的优化设计紧密相关。必须对沥青的类型和剂量，矿物质添加量以及可加工性进行表征和优化。这项研究旨在提供一种使用旋转粘度计对CBE材料进行基本表征的方法。首先，通过比较使用传统的主轴几何形状和设计用于避免相分离的新型叶轮：双螺旋带（DHR）所获得的结果，研究了使用Brookfield粘度计测量CBE浆料粘度的方法。之后，对矿物质添加量和沥青乳液类型的影响进行了测量和建模，同时考虑了其浓度的影响。事实证明，Krieger-Dougherty模型是拟合结果并为改进CBE材料工程表征提供基本参数的强大工具。总体而言，发现DHR被认为是CBE浆料流变学表征的有前途的工具。
