This article reviews the advances of using nanomaterials in hot mix asphalt. Clay nanoparticles are raw materials used in the manufacture of asphalt. Adding nanoparticles such as nanoparticles, nanosilica and nanotubes to asphalt typically increases the viscosity of asphalt binders and improves the wear and tear resistance of asphalt mixtures. Using nanoclay as a second modifier in polymer modified asphalt can improve storage stability and aging resistance of polymer modified asphalt. Nanotechnology has gradually infiltrated the asphalt industry. It now appears that the magical effects of nanomaterials have been proposed to improve asphalt performance. To illustrate many prospective applications, researchers have undertaken a series of positive and effective measures in preparing modified asphalt to demonstrate the modification mechanism and improve the result of its performance. In this study, first, different nanomaterials used in asphalt modification are presented, and then the methods used in asphalt modification with these materials and finally the impact of nanomaterials on basic asphalt performance and modification mechanisms are discussed.

Premature pavement breakdown can be caused by permanent deformation that can contribute to lower riding comfort for road users and an increase in maintenance costs. Dynamic modulus Simple Performance Test (SPT) test are considered to be significant in describing the permanent deformation of hot mix asphalt. In this study, Marshall method of mix design were used in order to prepare four asphalt mixtures comprising different content of Nanopolyacrylate (NP) polymer (0%NP, 2%NP, 4%NP and 6%NP). This study was aimed to evaluate the influence of the NP modified mixture on the permanent deformation. The Performance Grade PG64-22 was obtained by mixing the conventional bitumen (PG64-22) with nanopolyacrylate. Dynamic Shear Rheometer (DSR) at different aging condition were conducted in order to characterise the bitumen performance. While, the Simple Performance Test (SPT) was used to characterize rutting and fatigue on Marshall HMA mixes. Results from the study presented that, NP modified bitumen has a significant impact on the dynamic and rutting resistance. The addition of nanopolyacrylate significantly enhances the rheological properties of asphalt bitumen. The results revealed that 4%NP has high potential to improve rutting and fatigue resistance
