Abstract

The increase in traffic volumes and the rising cost of bitumen make it necessary to enhance the performance of asphalt binders through bitumen modification. Various types of nanomaterials have been used as additives to bitumen to improve the properties of asphalt mixtures, particularly in terms of resistance to aging, cracks caused by stress and temperature changes, moisture-induced damage, and permanent deformation. Several relevant studies have been reviewed, focusing on nanomaterials such as Nano Calcium carbonate, nano-silica, and carbon nanotubes. Additionally, the effect of fiber additives in asphalt mixtures has been examined, highlighting the different types of fibers used, their properties, testing methods, and mix design tests for fiber-reinforced asphalt mixtures. A wide variety of fiber types have been used in asphalt mixtures, including natural fibres and synthetic fibres. Recycled fiber materials, such as newsprint fibers, carpet fibers, and recycled tire fibers, have also been utilized. This review summarizes the performance of nanoparticles and fibers as asphalt modifiers. Several relevant studies have been reviewed, addressing nanomaterials and fibers.
