Abstract

VARGAS, Xiomara  and  REYES, Freddy. Asphalts' aging phenomenon . Ing. Investig. [online]. 2010, vol.30, n.3, pp.27-44. ISSN 0120-5609.

 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.

Keywords : aging; oxidation; asphalt.
