The aging of the asphalt mixture is attributed to various internal and external variables, with cracking and fissuring being among the most common, which adversely affects the pavement's durability. In warm climates like the Province of Huaura, this oxidative phenomenon is primarily driven by temperature fluctuations. Therefore, the aim of this study is to assess whether the inclusion of agro-industrial ashes can mitigate oxidative damage to the asphalt mixture by enhancing its physical and rheological properties. To achieve this, agro-industrial ashes were added to the conventional asphalt mixture at 3%, 7%, and 11%. Short-term aging effects were simulated through the use of the Rolling Thin Film Oven Test (RTFOT) method, which analyzed penetration, softening point, rotational viscosity, and ductility parameters, as well as the Dynamic Shear Rheometer (DSR) test, which examined the complex modulus and phase angle to evaluate the asphalt mixture's properties before and after aging. Aging indices were also calculated, with results indicating increased mixture stiffness and reduced thermal susceptibility of the material. Furthermore, it improved its elastic behavior and resistance to deformation. Ultimately, the 3% incorporation of agro-industrial ashes proved to be optimal in enhancing the mixture's resistance to oxidation.
