Resumo: | Red mud is the solid waste from bauxite processing during aluminium production. Its inadequate disposal causes social, economic and environmental prejudices. The industrial solid waste insertion evaluation in the production chain is beneficial and necessary. This work aims to evaluate the mechanical performance of asphalt mixtures produced with red mud as filling material. Asphalt mixtures with 5% and 7% red mud were produced, and permanent deformation and moisture-induced damage tests were carried out. A mixture without red mud addition (control) was produced for comparison. The results showed that the mixtures with red mud presented permanent deformation resistance greater than the control one, with more than 40% reduction in rutting deformation. The moisture damage did not significantly affect the mixtures tested. The red mud application as a filler in asphalt mixtures is viable and can be an alternative to reduce the damage such a waste can cause to the environment. |

A disposição inadequada gera prejuízos sociais, econômicos e ambientais. A avaliação da inserção de resíduos industriais na cadeia produtiva é benéfica e necessária. Este trabalho objetiva avaliar o desempenho mecânico de misturas asfálticas produzidas com lama vermelha como material de enchimento. Foram produzidas misturas asfálticas com 5% e 7% de lama vermelha e realizados ensaios de deformação permanente e de dano por umidade induzida. Uma mistura sem adição de lama vermelha (controle) foi confeccionada para comparação. Os resultados mostraram que as misturas com lama vermelha apresentaram resistência à deformação permanente superior à mistura controle, com redução de afundamento maior que 40%. O dano por umidade induzida não afetou significativamente as misturas testadas. A aplicação de lama vermelha como fíler em misturas asfálticas é viável e pode ser uma alternativa para reduzir os danos que este resíduo pode causar ao meio ambiente.Instituto Federal de Educação, Ciência e Tecnologia do Rio Grande do Norte2023-12-18info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionTextoapplication/pdfapplication/pdfhttp://www2.ifrn.edu.br/ojs/index.php/HOLOS/article/view/1634410.15628/holos.2023.16344HOLOS; v. 5 n. 39 (2023): v.5 (2023)1807-1600reponame:Holosinstname:Instituto Federal do Rio Grande do Norte (IFRN)instacron:IFRNporenghttp://www2.ifrn.edu.br/ojs/index.php/HOLOS/article/view/16344/3873http://www2.ifrn.edu.br/ojs/index.php/HOLOS/article/view/16344/3874Brasilhttps://creativecommons.org/licenses/by-nc-nd/4.0info:eu-repo/semantics/openAccessPadilha Thives, LiseaneSarisariyama Siverio Lima, MayaraRohde, Luciana2023-12-28T03:14:36Zoai:holos.ifrn.edu.br:article/16344Revistahttp://www2.ifrn.edu.br/ojs/index.php/HOLOSPUBhttp://www2.ifrn.edu.br/ojs/index.php/HOLOS/oaiholos@ifrn.edu.br||jyp.leite@ifrn.edu.br||propi@ifrn.edu.br1807-16001518-1634opendoar:2023-12-28T03:14:36Holos - Instituto Federal do Rio Grande do Norte (IFRN)false |

Red mud is the solid waste from bauxite processing during aluminium production. Its inadequate disposal causes social, economic and environmental prejudices. The industrial solid waste insertion evaluation in the production chain is beneficial and necessary. This work aims to evaluate the mechanical performance of asphalt mixtures produced with red mud as filling material. Asphalt mixtures with 5% and 7% red mud were produced, and permanent deformation and moisture-induced damage tests were carried out. A mixture without red mud addition (control) was produced for comparison. The results showed that the mixtures with red mud presented permanent deformation resistance greater than the control one, with more than 40% reduction in rutting deformation. The moisture damage did not significantly affect the mixtures tested. The red mud application as a filler in asphalt mixtures is viable and can be an alternative to reduce the damage such a waste can cause to the environment. |
