Investigating the benefits of utilising nanomaterials in enhancing the properties of bitumen and asphalt mixtures’ (Review Study)

Abstract

This paper aims to review the main benefits of utilising nanotechnology and adding nano materials and its impact on enhancing bitumen characteristics and asphalts mixers properties. In modern science and technologies that based on Nano measures, a huge attention was paid to take advantage from the scale of nanometre in various apparatus, equipments and new schemes while being able to control this minor measure. For many past years, nanotechnology has been considered as an interesting topic to be studied by many researchers and engineers. These technologies have been spread wildly as nanotechnology proven its ability to enhance the life quality, and to achieve economical and environmental enhancements. Consequently, the largest countries such as Japan, US and many others paid a huge attention to invest in one of the nanotechnologies applications. The main results that this study addressed is that adding various types of nano-particles to asphalt mixtures such as nanosilica, nano-clay, and nanotubes enhances the resistance abilities of asphalt such as the rutting and fatigue resistance and enhance the asphalt binders’ viscosity.

Keywords: Nanotechnology, nano-particles, Nano-clay; Nanotubes; Nanosilica, Asphalt mixtures.
