The mineral filler is an integral constituent of asphalt mixture, which affects its performance. This research investigates the effect of using four local industrial waste/by-product materials (marble, granite, steel slag and hydrated lime powder) as mineral fillers on asphalt mixtures characteristics. The detailed performance of these materials as well as asphalt binder and asphalt mixture characteristics are presented. In Egypt, limestone powder is a typical mineral filler in asphalt mixture composition. A control asphalt mixture with limestone mineral filler is designed using Marshall method. Other four asphalt mixtures are prepared using similar constituents and volumetrics except replacing the limestone filler with other types of industrial waste/by-product materials, while maintaining the same percentage of mineral filler as in the control mix. Marshall stability and moisture-induced damage of the investigated asphalt mixtures are determined and compared to the control asphalt mixture results. In addition, the performance characteristics of the investigated mixtures are evaluated by conducting cyclic performance tests including the dynamic modulus (E*) and flow number (FN). Testing results show that the asphalt mixture containing marble as a filler yields the highest stability; while, the hydrated lime filler noticeably enhances the performance of the asphalt mixture in terms of moisture damage resistance, E*, and FN. Unexpectedly, steel slag filler does not improve the asphalt mixture performance. Finally, the stiffness of the investigated mixtures is evaluated using three well-known E*-predictive models (NCHRP 1-37A, Hirsh, and NCHRP 1-40D); while, the resistance of the investigated mixtures to permanent deformation is evaluated using a calibrated version of Apeagyei-literary model based on the investigated mixtures to predict FN at 54.4°C and 1 Hz frequency.

矿物填料是沥青混合料的组成部分，影响其性能。本研究调查了使用四种当地工业废料/副产品材料（大理石、花岗岩、钢渣和熟石灰粉）作为矿物填料对沥青混合料特性的影响。介绍了这些材料的详细性能以及沥青粘合剂和沥青混合料的特性。在埃及，石灰石粉是沥青混合料组合物中典型的矿物填料。采用马歇尔法设计了一种含有石灰石矿物填料的对照沥青混合料。除了用其他类型的工业废料/副产品材料代替石灰石填料外，其他四种沥青混合物使用相似的成分和体积制备，同时保持与对照混合物中相同百分比的矿物填料。测定了所研究的沥青混合物的马歇尔稳定性和水分引起的损坏，并与对照沥青混合物的结果进行了比较。此外，通过进行循环性能测试，包括动态模量（E *) 和流量编号 (FN)。试验结果表明，以大理石为填料的沥青混合料稳定性最高；同时，熟石灰填料显着提高了沥青混合料的抗湿损性能、E *和FN。出乎意料的是，钢渣填料并没有改善沥青混合料的性能。最后，使用三个著名的E *-预测模型（NCHRP 1-37A、Hirsh 和 NCHRP 1-40D）评估所研究混合物的刚度；同时，使用基于所研究混合物的校准版本的 Apeagyei-literary 模型来评估所研究混合物的抗永久变形能力，以预测 54.4°C 和 1 Hz 频率下的 FN。
