<p>Sawdust is an organic residue formed when wood is chopped or sawed. With the aim of waste reduction, an attempt was undertaken to determine the viability of sawdust as a filler in asphalt mix. The disadvantage of utilizing sawdust is that it is extremely absorbent, which might lead to increased asphalt binder absorption. Therefore, chemical treatment is done with zycosil to reduce absorption. The optimal zycosil-to-water ratio is found as ZWB10 and water absorption is reduced by 84.62% compared to untreated sawdust. Given that sawdust has a substantially lower density than stone dust, a volume proportioning scheme has been used over a weight proportioning scheme to prevent using an excessive amount of filler in the mix. The physical properties of asphalt binder and aggregates are measured and found to be within the specified range. The fillers employed in this study include stone dust and sawdust, which are described using physical, chemical, and imaging techniques. The optimal binder content (OBC) for asphalt mix is established using stone dust, untreated sawdust, and treated sawdust as fillers, which are 5.88%, 6.60%, and 6.25%, respectively. The indirect tensile strength employing stone dust filler was 1.05 times more than that of treated sawdust. The moisture susceptibility values are within MoRTH requirements, but employing treated sawdust results in a 3% increase and a 42% reduction in abrasion loss. This study found that sawdust could be utilized as an alternate filler in asphalt mix.</p>
