<p>Increased traffic volumes and the relatively poor performance of traditional asphalt concrete mixtures have created a demand to improve bituminous material quality and, in turn, the performance of hot mix asphalt concrete mixes. As a result, innovative materials and techniques are necessary for road construction, upkeep, and renovation to guarantee better-performing pavements. In this study, bitumen is modified with inexpensive nanoparticles to create an asphalt concrete mix that is more affordable, simpler to manufacture, more climate change-friendly, and provides a sustainable solution. This work includes two different kinds of nanomaterials: Graphitic Carbon Nitride (G-C₃N₄) and Mesoporous Silica Nanoparticles (MSNs). While MSNs have been used to asphalt concrete mixes in the past, this work introduces G-C₃N₄ as a novel kind of bitumen nanomaterial additive. The mechanical properties of modified bitumen, asphalt concrete mixes, and nanomaterials under various circumstances were evaluated in a laboratory setting. Various percentages of nanoparticles were added to the bitumen, and the results were compared to the control samples. Nanomaterials were tested in laboratories using x-ray diffraction and transmission electron microscopy. Dynamic Shear Remoter (DSR), Rotational Viscometer (RV), Fourier transform infrared spectroscopy, thermogravimetric analysis, and scanning electron microscopy were among the methods used to test bituminous materials. The modified bitumen’s properties were significantly improved as compared to the control samples, according to test results. A significant improvement in performance grade was shown by the DSR data, increasing resistance to permanent deformation. Both Marshall stability and maintained strength of indirect tensile strength were improved by the asphalt concrete mix including modified bitumen.</p>
