ABSTRACT

Extreme temperature fluctuations in the central highlands of Peru cause significant deterioration of conventional asphalt pavements, particularly in high-altitude regions like the Mantaro Valley, impacting transportation safety and economy. This study evaluates the influence of beeswax (Organic Wax, OW) on the performance of Hot Mix Asphalt 85/100 for cold climates. The methodology involved testing conventional and SBS-modified asphalt mixtures with OW concentrations of 0.5%, 1%, 2%, and 4% at production temperatures of 100℃, 120℃, and 130℃. Performance was assessed using the Marshall, Lottman (indirect tensile strength), and Cantabro (abrasion) tests. The results showed that the optimal performance was achieved with the SBS-modified mixture containing 2% OW and produced at 120℃, which yielded a stability of 18.51 kN, a flow of 3.10 mm, air voids of 5.31%, and an adhesion loss of 8.55%. Furthermore, an OW dosage of at least 1% was found to be necessary to ensure adequate resistance to moisture damage, achieving a Tensile Strength Ratio (TSR) of approximately 80%. These findings confirm that modifying asphalt with beeswax enhances the durability and performance of pavements, making them more resilient to the extreme climatic conditions of the Mantaro Valley.
