The 4 mm parallel plate geometry in the DSR with a new sample installation method is proposed to evaluate low temperature rheological properties of asphalt binders. For this purpose, the influences of temperature conditioning and normal force were studied, and finally suitable test conditions were identified to run T-f-Sweep tests in oscillation mode. Appropriate shear stresses were identified by amplitude sweep tests considering the instrument limitations. Consequently, testing conditions and instrument limitations are determined, which need to be respected to obtain precise and repeatable rheological data.

使用 DSR 4 mm 几何形状进行低温粘合剂测试

建议在 DSR 中使用新的样品安装方法使用 4 mm 平行板几何形状来评估沥青结合料的低温流变特性。为此，研究了温度调节和法向力的影响，最终确定了合适的测试条件，以在振荡模式下运行 Tf-Sweep 测试。考虑到仪器限制，通过振幅扫描测试确定了适当的剪切应力。因此，确定了测试条件和仪器限制，需要遵守这些条件以获得精确和可重复的流变数据。
