Mineral fillers used in asphalt concrete mixtures have significant impacts on their performance. In this study, bagasse ash, a waste material of the sugar refining industry is utilized as a filler material in asphalt concrete for performance evaluation of asphalt concrete. It is used in varying percentages with partial and full replacement of stone dust which is conventionally used as filler. A comparative study between the conventional filler stone dust and the modified filler using bagasse ash is presented. Optimum binder content is determined using Marshall mix design method in accordance with MS-2 Asphalt Institute mix design method. Mixtures prepared exhibit good results and conform to the general specifications. The performance testing includes dynamic modulus test and wheel tracking test. The rut depth of modified sample such as with bagasse ash reduced as compared to conventional samples mostly at 100% replacement of filler. The dynamic stiffness is high at higher filler contents, and with 100% replacement. The results show that bagasse ash can be used as a filler material in partial or full replacement of the conventional stone dust filler.

沥青混凝土混合物中使用的矿物填料对其性能有重大影响。在这项研究中，糖精制工业的废料甘蔗渣灰被用作沥青混凝土的填充材料，以评估沥青混凝土的性能。它以不同的百分比使用，部分和完全替代了通常用作填充剂的石屑。进行了常规填料石粉尘和使用蔗渣灰的改性填料之间的对比研究。最佳粘合剂含量是根据MS-2沥青研究所的混合设计方法，使用马歇尔混合设计方法确定的。制备的混合物显示出良好的结果并符合一般规格。性能测试包括动态模量测试和车轮跟踪测试。与常规样品相比，改性样品（例如甘蔗渣灰）的车辙深度主要是在100％更换填料的情况下降低的。填料含量较高时，动态刚度很高，并且可以100％替代。结果表明，甘蔗渣灰可以用作填充材料，以部分或完全替代传统的石材粉尘填充剂。
