A laboratory study was done on three bitumen of penetration grade 50/70 from three sources and three corresponding mastics made using these three base bitumen and one filler – Limestone. The tests were all done using the Dynamic Shear Rheometer (DSR), including frequency sweeps for rheology, single stress creep recovery test (SSCR) for permanent deformation behaviour, Dresden cryogenic test (DDCT) for low temperature performance, and fatigue testing using column specimen. The frequency sweep data was modelled using the 2 Spring-2 Parabolic-1 Dashpot (2S2P1D) rheological model. Selected tests were carried out on unaged and aged bitumen and mastic samples to investigate the sensitivity of the materials to ageing. Performance diagrams were made which could enable in bitumen and mastic selection based on specified desired criteria. It was found that bitumen from different bitumen producers and provenances had different performance behaviours. Furthermore, the addition of the limestone filler also affect the ranking based on specified behaviours.

对来自三种来源的渗透等级为50/70的三种沥青和使用这三种基础沥青和一种填料Limestone制成的三种相应的胶泥进行了实验室研究。所有测试均使用动态剪切流变仪（DSR）进行，包括用于流变学的频率扫描，用于永久变形行为的单应力蠕变恢复测试（SSCR），用于低温性能的德累斯顿低温测试（DDCT）以及使用柱样本进行的疲劳测试。使用2 Spring-2 Parabolic-1 Dashpot（2S2P1D）流变模型对频率扫描数据进行建模。对未老化和老化的沥青和乳香样品进行了选定的测试，以研究材料对老化的敏感性。绘制了性能图，可以根据指定的期望标准进行沥青和乳香的选择。发现来自不同沥青生产商和来源的沥青具有不同的性能行为。此外，石灰石填料的添加也会影响基于特定行为的排名。
