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

将改性剂用于沥青粘合剂已成为提高沥青材料性能的常用方法。结果，粘合剂变得更复杂，具有各种相形态。传统的测试方法可能并不总是合适的。例如，欧洲标准化委员会正在研究表征聚合物改性沥青的不同方法。RILEM技术委员会272-PIM“创新沥青材料的相和相行为”及其任务组TG1正在评估复杂粘合剂的不同测试方法。目的是评估这些测试如何处理复杂的沥青粘合剂。与17个实验室进行了实验室间计划。评价了七种粘合剂；两个是纯沥青，两个是PmB。除了常规的性能测量外，在研究从动态剪切流变仪测量获得的各种流变参数方面进行了广泛的努力。鉴于对PmB的欧洲产品标准EN 14023的未来修订，提出并讨论了一些初步结果。
