Evaluation of anti-reflective cracking mixtures made with high NFU asphalts

Abstract

The world's environmental problems are diverse, among them waste and particularly end-of-life tires (ELTs). The shredding of these tires and their use in construction materials such as asphalt mixtures is one of the techniques with the greatest potential for use. On the other hand, in the search to obtain asphalts with high elastic performance and fatigue responses, in recent years, different asphalt modifiers have been studied and NFUs have been one of them. With the aim of obtaining improvements in the mentioned properties, a greater incorporation of NFU and its application in reflex cracking retardant mixtures has been studied. For this purpose, in the present work, different asphalt mixtures made with asphalt with a high rate of NFU incorporation by wet method have been evaluated. The evaluation of their physical behavior has allowed comparing them and estimating which of them would present the best performance as anti-reflective cracking mixtures.
