Resumo: The objective of this work was to evaluate the performance of the mechanical resistance of the discarded clay and residual lateritic tropical soil mixture in order to provide an environmentally adequate destination for the residue through its application in base layers and sub-base of flexible pavements. The mixtures were composed of 100% solids, 100% discarded clarifying clay (DCC), 05% DCC + 95% solids, 10% DCC + 90% solids, 20% DCC + 80% 70% soil and 40% DCC + 60% soil, totalizing seven experimental units. To evaluate the mechanical performance, the Proctor and California Support Index (CBR) compaction tests were carried out at intermediate and modified energies. The mixtures obtained similar granulometric behavior to the local soil, observing a change of the fine fraction due to the increase of the same residue. The results of mechanical resistance indicated a better performance of the mixtures with 10% of DCC + 90% soil and 20% of DCC + 80% soil, in the modified energy, being recommended as material for the execution of pavements. For the other mixtures, it is recommended only the use in the execution of sub-bases of flexible pavements.

Foram utilizadas misturas compostas por 100% solo, 100% argila clarificante descartada (ACD), 05% ACD + 95% solo, 10% ACD + 90% solo, 20% ACD + 80% solo, 30% ACD + 70% solo e 40% ACD + 60% solo, totalizando sete unidades experimentais. Para avaliação do desempenho mecânico, foram realizados os ensaios de compactação Proctor e Índice de Suporte Califórnia (CBR), nas energias intermediária e modificada. As misturas obtiveram comportamento granulométrico similar ao solo local, observando-se uma alteração da fração fina devido o incremento do resíduo as mesmas. Os resultados de resistência mecânica indicaram um melhor desempenho das misturas com 10% de ACD + 90% solo e 20% de ACD + 80% solo, na energia modificada, sendo recomendadas como material para execução de base de pavimentos. Para as demais misturas, recomenda-se apenas o emprego na execução de sub-bases de pavimentos flexíveis.Universidade Federal de Santa Maria2022-08-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdftext/htmlhttps://periodicos.ufsm.br/reget/article/view/3917110.5902/2236117039171Revista Eletrônica em Gestão, Educação e Tecnologia Ambiental; REGET 2020-1; e44Revista Eletrônica em Gestão, Educação e Tecnologia Ambiental; REGET, v. 24, 2020.
