Resumo: | Studies involving the use of iron ore tailings from the beneficiation process in different market niches are increasingly necessary due to the large environmental damage caused by their disposal in dams, since they are waste generated in high volumes and which have low economic value for mining companies The main purpose of this study was to investigate mechanical properties of hot mix asphalt mixture containing iron ore flotation tailing. For this, a mixture containing iron ore flotation tailing and a control mixture with natural aggregates and stone dust were prepared according to the Marshall methodology and tests of stability and flow, indirect tensile strength, resilient modulus, fatigue test and dynamic creep tests were conducted. Results show that the mixture with iron ore flotation tailing had performed technically appropriate, due to the similarity of mechanical properties of the control mixture. Therefore, the results obtained revealed that the iron ore flotation tailing presented technical characteristics appropriate to its use incorporated into hot mix asphalt. In addition, their use as an alternative material in asphalt pavements can generate environmental benefits by reducing the volume of material deposition in tailings landfills and exploration areas for mineral aggregate mining. |

El objetivo de este trabajo fue analizar el comportamiento mecánico de una mezcla asfáltica densa, con relaves de flotación de mineral de hierro en sustitución del relleno de agregados minerales, en comparación con el comportamiento de una mezcla compuesta únicamente por agregados naturales. Para ello, se dosificaron las mezclas, según la metodología Marshall, y se realizaron ensayos de estabilidad y fluencia, resistencia a la tracción, módulo de resiliencia, fluencia dinámica y vida a fatiga. Los resultados obtenidos en esta investigación revelaron que los relaves de flotación de mineral de hierro presentaban características técnicas adecuadas para su uso, como un material fino para ser incorporado en mezclas asfálticas densas. Además, su uso como material alternativo en revestimientos asfálticos puede generar beneficios ambientales, reduciendo el volumen de material descartado en presas de relaves y reduciendo las áreas de exploración de depósitos para la extracción de agregados minerales.Estudos envolvendo a utilização de rejeito de flotação resultante do processo de beneficiamento do minério de ferro, em diferentes nichos de mercado, se mostram cada vez mais necessários diante do grande passivo ambiental causado pela sua disposição em aterros, uma vez que se tratam de resíduos gerados em grandes volumes e que apresentam baixo valor econômico para as empresas mineradoras. O objetivo desse trabalho foi analisar o comportamento mecânico de uma mistura asfáltica densa, com rejeito de flotação de minério de ferro em substituição ao fíler de agregado mineral, em comparação ao desempenho de uma mistura composta somente por agregados naturais. Para isso, as misturas foram dosadas, segundo a metodologia Marshall, e realizados ensaios de estabilidade e fluência, resistência a tração, módulo de resiliência, creep dinâmico e vida de fadiga. Os resultados obtidos nesta pesquisa revelaram que o rejeito de flotação de minério de ferro apresentou características técnicas adequadas ao seu aproveitamento, como material fino, a ser incorporado a misturas asfálticas densas. Além disso, o seu emprego como material alternativo em revestimentos asfálticos pode gerar benefícios ambientais, reduzindo-se o volume de material descartado em barragens de rejeitos e a redução de áreas de exploração de jazidas para extração de agregados minerais.Research, Society and Development2021-12-22info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/2422010.33448/rsd-v10i17.24220Research, Society and Development; Vol. 10 No. 17; e122101724220Research, Society and Development; Vol. 10 Núm. 17; e122101724220Research, Society and Development; v. 10 n. 17; e1221017242202525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIenghttps://rsdjournal.org/index.php/rsd/article/view/24220/21414Copyright (c) 2021 Sérgio Pacífico Soncim; Jonas Henrique de Carvalho Oliveira; Marconi Oliveira de Almeida; Carlos Augusto de Souza Oliveira; Fernanda Maria Belotti; Erinaldo Hilário Cavalcante; Lais Resendehttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessSoncim, Sérgio Pacífico Oliveira, Jonas Henrique de Carvalho Almeida, Marconi Oliveira de Oliveira, Carlos Augusto de Souza Belotti, Fernanda Maria Cavalcante, Erinaldo Hilário Resende, Lais2022-01-01T11:11:08Zoai:ojs.pkp.sfu.ca:article/24220Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:42:51.347648Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
