Estudio comparativo del comportamiento del hormigón para pavimento rígido, elaborado con diversos materiales reciclados: PET, caucho, vidrio y escoria como sustitutos de agregados

Abstract

Abstract: This study analyzes the behavior of concrete for rigid pavement by incorporating recycled materials such as PET, rubber, glass and steel slag in various proportions as partial substitutes for traditional aggregates, for which compressive and flexural strength tests were applied to evaluate the mechanical performance of the mixtures, comparing them with a conventional concrete base. The results indicate that the substitution with recycled materials has a significant impact on the mechanical properties, highlighting slag as the most efficient material in flexural and compressive strength. It was also proven that the incorporation of these wastes promotes sustainability, reduces the use of natural resources and lowers costs, contributing to the circular economy and to more responsible construction practices. This research proposes a viable alternative to integrate environmental criteria in the design of rigid pavements, responding to the current challenges of civil engineering.
