Abstract

Rutting is a key factor affecting the safety, durability, and performance of asphalt pavements. Its effective control requires proper design, material selection, and construction practices. Reclaimed Asphalt Pavement (RAP) offers environmental and economic advantages by reducing the need for virgin materials and minimizing construction waste. Incorporating RAP and basalt fibers can further enhance rutting resistance, thereby improving pavement longevity and structural performance. This study investigates the development of reclaimed asphalt pavement (RAP) mixture using. The RAP content was set at 15%, 30%, and 45%, with the addition of 6 mm long and 3‰ basalt fibers. The Hamburg wheel tracking test was used to evaluate the mixture's resistance to permanent deformation. The results indicated a decrease in rut depth and surface peeling as the RAP content increased. Notably, asphalt mixtures with 0% RAP and 3‰ basalt fibers demonstrated lower rut depths compared to control samples. The experiments showed that RAP mixtures exhibit superior rutting resistance compared to hot mix pavements. Additionally, integrating recycled materials and basalt fibers significantly enhanced rutting resistance, as evidenced by the incorporation of 45% RAP and 3‰ basalt fiber, which resulted in nearly a 47% decrease in rutting depth. Future research may focus on evaluating the crack resistance of asphalt pavements reinforced with high tensile strength basalt fibers.
