Abstract
Recently, with the advent of nanotechnology and the manufacture of nanoparticles, a huge change has taken place in the functional demands of materials. The role of the pavement surface layer, which is made of asphalt mixtures, in the performance of pavements is inevitable. The use of nanotechnology in the construction of transportation infrastructure is roughly equivalent to the human effort to send humans to the moon in the 1960s. In 2005, the idea of building asphalt for highways that could repair themselves seemed far-fetched to many. Therefore, the asphalt industry still needs a transformation so that people can see the possibilities of nanotechnology and understand its benefits. Due to the compositional nature of the asphalt mix, the potential for improvement in the mechanical properties of asphalt using nanotechnology is very important. Modification of nanomaterials began with engineering changes in the molecular structure of asphalt with the aim of influencing the properties of these materials. Nanoscale modifiers can react with bitumen to change the chemical and molecular structure of the bitumen, which can lead to better asphalt performance. In recent years, the use of nanoparticles in changing the behavioral and chemical properties of asphalt has been considered by researchers and researchers have conducted numerous experiments to study these properties in order to improve the properties of asphalt mixtures made with nanoparticles, but this science still needs To more extensive research in order to achieve more comprehensive and accurate results. This paper reviews the studies on the effect of different nanoparticles on the production of cold asphalt in factories produced with emulsion bitumen.
