| Summary: | The paper presents the evolution of the resilient modulus, permanent vertical deformation, and fatigue law of hot mix asphalt (HMA) when exposed to the weather conditions in the city of Bogotá D.C. (Colombia) for 29 months. The trend of mixture with the exposure time is to experience an increase in stiffness values, mainly due to age-hardening process of the asphalt binder. This increase in stiffness creates increased resistance to permanent deformation and decrease in fatigue life of the analyzed mixture. Based on the resilient modulus evolution with time of exposure to the environment an equation to predict approximately the change for the fatigue life of the mixture is proposed.
