ABSTRACT
The main objective of this research is to evaluate the mechanical behavior of hot asphalt mixtures with the incorporation of corn cob ash and fiberglass, in the city of Huancayo, Peru. The adopted methodology includes a quantitative design and an experimental approach, where 40 asphalt mix briquettes were prepared, of which 22 contained additives in proportions of corn cob ash (0.5%, 1.0%, 1.5% and 2.0%) and 1.5% fiberglass. Marshall stability and dynamic modulus tests, viscosity and water sensitivity analysis, and permanent deformation were performed. The results showed that the mixture with 1.5% corn cob ash and 1.5% fiberglass reached a maximum stability of 1195.8 kg and a yield of 3.66 mm. In addition, a reduction in the mixture voids was observed, reaching 4.02% with 2% ash. However, resistance to moisture damage was lower in the mixture with 0% ash and 1.5% fiber, with a value of 5.39 kg/cm虏. Likewise, the addition of corn cob ash and fiberglass improved rutting depth and the number of passes, generating the lowest deformation, 4.8 mm, with 2% ash and 1.5% fiber. In conclusion, the addition of corn cob ash and fiberglass improves the durability of asphalt mixtures, although their proportion must be optimized to balance moisture resistance and structural stability.
