Abstract

The incorporation of waste materials into asphalt pavements has gained increasing attention as a sustainable and environmentally responsible approach to road construction and maintenance. This study examines the performance of asphalt mixtures incorporating foliated quartzite waste and rubber asphalt for road pavements. Despite deviations in certain parameters from recommended standards, such as sand equivalent and Los Angeles abrasion, alternative materials like quartzite waste can still be viable for asphalt mixtures if they ensure structural integrity. Mechanical tests reveal that the asphalt rubber and quartzite waste mixture exhibit superior tensile strength and resilience modulus compared to reference mixtures, suggesting enhanced load-bearing capacity and resistance to deformation. This study underscores the versatility of utilizing materials like quartzite waste and rubber from scrap tires in road pavement applications, advocating for further exploration of their suitability, particularly in regions with extensive road networks and diverse environmental conditions. Furthermore, the adoption of these materials promotes environmental sustainability by mitigating environmental damage and reducing the consumption of conventional aggregates in pavement construction, thereby fostering a more sustainable approach to infrastructure development.
