Efecto de la Temperatura en la Evaluación de la Fatiga en Ligantes Asfálticos

Abstract: La fatiga es uno de los modos de falla más comunes en los pavimentos flexibles, la cual es caracterizada por la interconexión de grietas longitudinales y transversales provocadas por los esfuerzos de tensión que se generan en la base de la carpeta asfáltica, debido al tránsito pesado.El presente trabajo evalúa la influencia de la temperatura en el comportamiento a la fatiga de ligantes asfálticos, de acuerdo a dos métodos de ensayo: Grado PG y Barrido de Amplitud Lineal (LAS). El estudio evalúa tres ligantes a… Show more

“…However, the current test protocol does not specify a test temperature for binders that have characteristics similar to those analyzed in this paper. Temperature is a relevant factor in evaluating the viscoelastic behavior and mechanical performance of an asphalt binder [ 62 ]. Therefore, the materials were tested at the same stiffness (G*), ensuring the cohesive failure of fatigue cracking in the specimen.…”
