###### Abstract  
This research delves into the realm of asphalt technology, exploring the potential of nano-additives to enhance traditional asphalt binder properties. Focusing on Nano-Titanium Dioxide (NT), Nano-Aluminum Oxide (NA), and Nano-Silica Oxide (NS), this study investigates the effects of incorporating these nanomaterials at varying dosages, ranging from 0% to 8%, on the asphalt binder's performance. This study employs a series of experimental tests, including consistency, storage stability, rotational viscosity, mass loss due to aging, and rheological properties, to assess the impact of nano-additives on asphalt binder characteristics. The findings indicate a substantial improvement in the consistency of the asphalt binder with the addition of nanomaterials, particularly NS, which shows a 41% reduction in penetration at an 8% content and a notable increase in the softening point. The storage stability tests reveal that NS-modified asphalt exhibits superior stability compared to NT and NA, with a significantly lower \(\Delta\)T increase. Furthermore, the investigation into rotational viscosity suggests that NS, despite increasing the binder's viscosity, does not exceed the AASHTO M320 threshold, ensuring the binder's workability. Aging tests demonstrate that NT, at lower concentrations, acts as an effective anti-aging agent, whereas NA and NS tend to increase the mass loss, impacting thermal stability. This study concludes that while each nanomaterial uniquely influences the asphalt binder's properties, NS stands out in terms of enhancing the high-temperature performance and storage stability. Optimal dosages of 6% for NT and NA and 4% for NS are recommended based on the Overall Desirability analysis. This research bridges the gap between traditional asphalt materials and modern requirements, highlighting the transformative impact of nano-additives in advancing asphalt pavement technology. N

improve the virgin asphalt cement's performance characteristics. These additives include polymers, fibers, and nanomaterial (NM), each contributing to enhancing the binder and asphalt concrete properties [7; 8; 9; 10; 11; 12; 13; 14; 15; 16]. Nanotechnology has experienced rapid development across various fields. In the realm of asphalt pavement, the addition of NMs to enhance the properties of asphalt binders has gained popularity over the past decade. This trend developed due to the unique attributes of NMs, such as their high stability, large surface area, chemical purity, and effective dispersion ability. Notably, there are significant differences in the chemical and physical properties of original raw materials and their nanoscale counterparts [17]. Basically, NMs are produced by reducing the dimensions of materials from a normal or original size to nano size, resulting in noticeable changes in the characteristics of the original materials, such as their mechanical properties and chemical reactivity. These materials typically have at least one dimension within the range of 1 to 100 nanometers and exhibit an increased surface area due to a higher proportion of atoms on the surface. This size reduction leads to altered surface morphologies, surface energies, and physicochemical properties of the original material [18; 19; 20; 21; 22; 23]. Research over the past decade, as summarized in Table 1, has focused on individual nanomaterial modifications in asphalt binders. This study expands upon these works by investigating three nanomaterials, NT, NA, and NS, at dosages of 0%, 2%, 4%, 6%, and 8% by weight of asphalt cement. Utilizing an Overall Desirability (OD) analysis, this research evaluates multiple properties such as penetration, softening point, and viscosity, aiming to determine optimal nanomaterial dosages for improved pavement performance. This comprehensive approach not only bridges the gaps of previous studies but also establishes guidelines for effective nanomaterial use for asphalt binder modifications.
