<![CDATA[This study evaluates the performance of asphalt concrete binder course (AC-BC) mixtures incorporating artificial coarse aggregates at replacement levels of 0%, 50%, and 100% using the Marshall method. The artificial coarse aggregate exhibited a Los Angeles abrasion value of 40% and an absorption of 6.69%, while the natural aggregate showed an abrasion value of 21.34% and an absorption of 5.33%. The 60/70 penetration asphalt binder used in this study had a penetration value of 64.6 dmm, ductility of 120 cm, specific gravity of 1.036, and a softening point of 38.5 °C. Marshall testing was conducted at a designed asphalt content of 5%. The results indicate that all mixtures achieved acceptable stability, flow, voids in mineral aggregate (VMA), and Marshall quotient values. However, all mixtures exhibited high voids in the mix (VIM) and low voids filled with asphalt (VFA), indicating insufficient effective asphalt content. This behavior is mainly attributed to the high absorption capacity of the artificial aggregates and the relatively low softening point of the asphalt binder. The mixture is not yet volumetrically feasible at 5% asphalt content, so it requires optimization of asphalt content or pre-treatment of artificial aggregates. The findings suggest that artificial aggregates may be utilized in AC-BC mixtures with appropriate adjustments to asphalt content and material properties.]]>
