Resumo: | The construction industry is responsible for a consumption of 20 to 50% of the existing natural resources on the planet. One way of mitigating the exploitation of natural aggregates extraction deposits and expanding the use of residues is the study of their application in paving. The present article technically analyzed the potential of application of construction and demolition waste (CD&W) in mixtures with sandy-silty soil as a possibility for reuse in the base layer of pavements. The guidelines of the new flexible pavement design method of the Departamento Nacional de Infraestrutura de Transportes (DNIT) propose that the analysis of the materials used in the pavement layers be carried out through the resilience module and permanent deformation. Thus, repeated load triaxial tests were carried out to determine the resilience modulus of soil-crushed and soil-CD&W mixtures in various proportions and later the design of a pavement structure was carried out using the MeDiNa software to verify if mixtures of soil with CD&W aggregates would provide structural base layers with performance comparable to that of conventional crushed rock. From the magnitude of the resilience module of the mixtures and the sizing, the potential of using the soil mixture with local waste in the pavement structure with specific design characteristics and thicknesses was verified. The design using the MeDiNa software proved the possibility of using the soil-CD&W 70-30 mixture in the base layer properly. |

Una forma de mitigar la explotación de yacimientos para la aplicación de áridos naturales y ampliar el aprovechamiento de los residuos es a través de estudios de pavimentación. El presente artículo analizó técnicamente el potencial de aplicación de residuos de construcción y demolición (RCD) en mezclas con suelo arenoso-limoso como posibilidad de reutilización en la capa base de pavimentos. Los lineamientos del nuevo método de diseño de pavimento flexible del Departamento Nacional de Infraestrutura de Transportes (DNIT) proponen que el análisis de los materiales utilizados en las capas de pavimento se realice a través del módulo de resiliencia (MR) y deformación permanente (DP).Así, se realizaron ensayos triaxiales de carga repetida para determinar el módulo de resiliencia de mezclas suelo-triturado y suelo-RCD en varias proporciones y posteriormente se realizó el diseño de una estructura de pavimento utilizando el software MeDiNa para verificar si las mezclas de suelo con agregados RCD proporcionaría capas base estructurales con un rendimiento comparable al de la roca triturada convencional. A partir de la magnitud del módulo de resiliencia de las mezclas y del dimensionamiento, se verificó el potencial de utilizar la mezcla de suelo con residuos locales en la estructura del pavimento con características de diseño y espesores específicos. El diseño con el software MeDiNa probó la posibilidad de utilizar correctamente la mezcla suelo-RCD 70-30 en la capa base.A indústria da construção civil é responsável por um consumo de 20 a 50% dos recursos naturais existentes no planeta. Uma maneira de mitigar a exploração de jazidas de extração de agregados naturais e ampliar a utilização de resíduos são os estudos da aplicação destes na pavimentação.O presente estudo analisou tecnicamente o potencial de aplicação dos resíduos de construção e demolição de obras (RCD) em misturas com solo areno-siltoso como uma possibilidade de reúso eficiente em camada de base de pavimentos. Tendo em vista as diretrizes do novo método de dimensionamento de pavimentos flexíveis do Departamento Nacional de Infraestrutura de Transportes (DNIT) analisar o desempenho mecânico de RCD em misturas com solo pelo módulo de resiliência (MR) e deformação permanente (DP) para verificar a viabilidade do emprego destes materiais nas camadas dos pavimentos é de fundamental importância. Desse modo, foram realizados ensaios triaxiais de carga repetida para determinação do módulo de resiliência de misturas de solo-brita e solo-RCD em várias proporções e posteriormente realizou-se o dimensionamento de uma estrutura de pavimento utilizando o software MeDiNa para verificar se misturas de solo com os agregados de RCD proporcionariam camadas estruturais de base com desempenho comparável ao de solo-brita. A partir da magnitude do módulo de resiliência das misturas e dos dimensionamentos verificou-se a potencialidade de emprego da mistura de solo com os resíduos locais na estrutura de pavimento com características de projeto e espessuras específicas. O dimensionamento utilizando o software MeDiNa comprovou a possibilidade da utilização da mistura de solo-RCD 70-30 em camada de base de forma adequada.Research, Society and Development2022-06-16info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/3031510.33448/rsd-v11i8.30315Research, Society and Development; Vol. 11 No. 8; e21911830315Research, Society and Development; Vol. 11 Núm. 8; e21911830315Research, Society and Development; v. 11 n. 8; e219118303152525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/30315/26433Copyright (c) 2022 Letícia Azevedo de Farias Pereira; Ênio Fernandes Amorim; Laura Maria Goretti da Mottahttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessPereira, Letícia Azevedo de Farias Amorim, Ênio Fernandes Motta, Laura Maria Goretti da 2022-07-01T13:34:06Zoai:ojs.pkp.sfu.ca:article/30315Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:47:07.060201Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
