Abstract
pavement materials are critical factors affecting the durability and performance of roads. Nowadays, there is a pressing need for roads that are more stable and capable of withstanding heavy traffic and adverse weather conditions. Pavement surfaces are often damaged by rutting, potholes, and other forms of deterioration. Among various materials, asphalt is considered one of the most sustainable and versatile materials for pavement construction, used widely in highways, airport runways, parking lots, and driveways.To enhance the durability of conventional asphalt, it has been modified using nano-materials, producing what is known as modified asphalt. This research focuses on the advances in the application of nano-materials in hot mix asphalt, as well as the addition of Recron fibre, with a comparison of their effects. The incorporation of Recron fibre improves the properties of bitumen, including an increase in stability, a reduction in flow value, and a decrease in air voids.Recron fibre, a synthetic material made from polyester, serves as secondary reinforcement to enhance tensile strength. It helps resist cracks caused by improper pavement laying and heavy vehicular loads. In contrast, clay-based nano-particles are primary modifiers in asphalt construction. Adding nano-materials such as nano-clay, nano-silica, and carbon nanotubes typically increases the viscosity of asphalt binders and enhances the rutting and fatigue resistance of asphalt mixtures.This study examines the performance and sustainability of asphalt treated with nano-particles and Recron fibre, comparing it to conventional pavement materials
