Mezclas asfálticas tibias con diversos porcentajes de partículas de vidrio reciclado, en sustitución de agregados

Abstract

Abstract: The use of recycled glass in asphalt mixtures is fundamental; it helps reduce solid waste, preventing large volumes of glass from ending up in landfills or in the environment, where its degradation is very slow. Furthermore, if natural aggregates are partially replaced with recycled glass, the extraction of stone materials is reduced. This, in turn, decreases ecosystem degradation, the use of non-renewable resources, and the environmental impacts related to mining activity. The behavior of a warm asphalt mixture incorporating 5%, 7.5%, and 10% crushed recycled glass, made with local aggregates, is analyzed. Considering a maximum nominal size of 12.5 mm, for the design of a warm mix for medium traffic, an Asfalplus additive was applied at a proportion of 3%, and the mixture was worked at temperatures between 110°C and 120°C. The results showed that asphalt mixtures with 7.5% recycled glass content exhibit appropriate technical performance, demonstrating their potential use as a wearing course.
