A UTILIZAÇÃO DO VIDRO MOÍDO COMO AGREGADO MIÚDO EM REVESTIMENTOS ASFÁLTICOS: UMA REVISÃO SISTEMÁTICA

Abstract

The study, understanding, and development of the road network are global interests of even greater importance in Brazil due to the frequent use of road transportation. To achieve sufficient proposition for the viability and expansion of Brazilian highways, considering economic and environmental needs, recycling industrial or domestic inputs with advantageous properties for improving pavement performance, longevity, and recovery can provide a solution to the problem of using materials with harmful environmental impact and high cost. The central objective of this dissertation was to evaluate the influence of adding ground glass as fine aggregate, in different proportions, in asphalt mixtures. As a secondary objective, the mechanical properties such as strength, stiffness, and durability of the mixture were investigated to assess the feasibility of its application. This is a systematic literature review with 18 publications between 2012 and 2022, on the Scientific Electronic Library Online (SciELO), Scopus, and Web of Science databases. It was observed that adding ground glass to asphalt pavements can improve the strength and flexibility of asphalt mixtures, depending on the percentage of mixture adjusted for the desired use. For traditional purposes, a percentage between 10% and 15% was suggested for optimal results, combined with other components to reduce vulnerability, and increase longevity. There is also a sense of systemic economy in this material, because it not only reduces direct costs but also helps to reduce environmental costs by generating less waste and thus promoting less environmental impact.
