LIGANTES ASFÁLTICOS MODIFICADOS COM RESÍDUOS: UMA REVISÃO DE LITERATURA

In Brazil, the paving of streets, avenues and roads is almost entirely executed with asphalt mixtures. In these mixtures, asphalt binder plays a fundamental role in cohesion, resistance to permanent deformation, fatigue and thermal cracking. Binder performance can be improved by the addition of modifiers such as SBS, EVA, HDPE, tire rubber, etc. This paper presents a literature review about residue modified asphalt binders, aiming to show what has been discussed and how is the real performance of these materials. The analysed papers were searched in the “Web of Science” database with key words filters to obtain the most relevant papers, whose results are presented. We identified an increasing use of polymeric modifiers, which shows that the properties of these materials are propitious for modified asphalt binders production.
