Due to high temperatures and repeated load, asphalt pavements commonly experience rutting distress, a challenge that can be considerably reduced by modifying the binder components. This research focused on evaluating the performance of asphalt binders with single-use masks (SUMs) when subjected to high temperatures. For this purpose, dynamic shear rheometer (DSR)-based frequency sweep, temperature sweep, and multiple stress creep recovery (MSCR) experiments were performed on various asphalt binders, including both unmodified and SUM-modified (SUMM) samples. To explore the effects of temperature, SUM content, and loading frequency on the rutting performance of the SUMM samples, a statistical modeling-based response surface methodology (RSM) was utilized, enabling the creation of predictive mathematical models. To investigate the internal morphology of the binders, fluorescence microscopy (FM) was applied. Data from rheological analyses revealed that the addition of SUM markedly boosted the high-temperature resistance of the asphalt binder. Findings from the MSCR analysis indicated that the SUMM samples achieved lower nonrecoverable compliance (J) and greater percent recovery (R) values than the reference asphalt, suggesting that SUMs significantly enhance the binder's resistance to rutting. Data analysis demonstrated that the chosen independent variables had a considerable effect on the asphalt's complex modulus (G*) and rutting performance (G*/sin (δ)), prompting the formulation of predictive models for rutting susceptibility. Moreover, the FM examination demonstrated that the SUM was homogeneously integrated across the asphalt matrix.
由于高温和反复荷载作用，沥青路面通常会出现车辙病害，而通过改性结合料成分可以显著降低这一挑战。本研究聚焦于评估使用过的一次性口罩（SUMs）对沥青结合料在高温下性能的影响。为此，对包括未改性和SUM改性（SUMM）样品在内的各种沥青结合料进行了基于动态剪切流变仪（DSR）的频率扫描、温度扫描和多重应力蠕变恢复（MSCR）试验。为了探究温度、SUM含量和加载频率对SUMM样品车辙性能的影响，采用了基于统计建模的响应面方法（RSM），从而建立预测数学模型。为了研究结合料的内部形态，应用了荧光显微镜（FM）。流变分析数据表明，添加SUM显著提高了沥青结合料的高温抗性。MSCR分析结果表明，SUMM样品的不可恢复柔量（J）值低于参考沥青，恢复百分比（R）值高于参考沥青，这表明SUMs显著增强了结合料的抗车辙能力。数据分析表明，所选自变量对沥青的复数模量（G*）和车辙性能（G*/sin(δ)）有显著影响，从而建立了车辙敏感性预测模型。此外，FM检测表明SUM在沥青基体中均匀分布。
