“…Campbell y Wright (1965 estudiaron los productos de la oxidación de los asfaltos soplados con aire mediante espectroscopia de infrarrojo, microviscosimetría y con el cambio del punto de ablandamiento. Behl, Traxler et al (1969) emplearon la técnica de luz dispersa para oxidar películas de asfalto. Encontraron una relación directa entre el índice de envejecimiento y la proporción de luz dispersa de un asfalto.…”

“…Wright (1965, 1966) studied the oxidetion products of air-blown asphalts using infrared spectroscopy, microviscosimetry and the change of softening point. Behl, Traxler et al, (1969) used the scattered light technique to oxidize asphalt films. They found a direct relationship between the aging index and the proportion of scattered light from the asphalt.…”

This work presents a state of the art revision of the results from studies of asphalt aging found by researchers aimed at deepening understanding of this complex phenomenon. The background shows the evolution of asphalt aging, initially considering it as physical hardening and progressively recognizing it as a complex phenomenon having repercussions on asphalt durability and physical-chemical properties. This document aims to be a guide for understanding future investigations for developing new types and mixtures of asphalt having improved properties.
