Resumo: The municipal district of Equador-RN is located in an area of great amounts of ores, being your main economical activity the extraction and the kaolin improvement. The main originating from environmental problem that activity is the amount of generated residue, about 70% of the extracted kaolin. The residues are simply piled up in lands of the improvement companies, occupying like this a large area and causing impact in the existent flora. When dry, the residues transform powdered and for the action of the wind, they disperse, polluting the air. Being like this, the present work has as objective evaluates the incorporation of the great residue, originating from of the kaolin improvement, in partial substitution of all the employed aggregates in a conventional mixture of asphalt concrete, which was used in the paving of BR101/RN061 - passage between Ponta Negra and Ares. That evaluation was accomplished in three stages. The first refers to the evaluation of the physical, thermal and mineralogical characteristics of the residue with the intention of to classify it and to define your application as aggregate (small and great). The second refers to the physical characterization of the aggregates and of the asphalt material used in the conventional mixture. And the third, to the evaluation of the mixtures containing residue, which were elaborated starting from the conventional mixture with the gradual incorporation of the residue, from 5 to 40%, in substitution to the part of the conventional aggregates, in way to obtain similar particle size curves the one of the conventional mixture. That evaluation was accomplished through the comparison between the volumetric composition, the mechanical behavior and the susceptibility to the humidity of the mixtures containing residue with the one of the conventional mixture, and with the one of the DNIT specifications. The results show that the great residue originating from of the kaolin improvement has grains of the most varied size, being like this, it can substitute part of all the conventional aggregates and of the filler in an asphalt mixture. Besides, your mineralogical composition presented the same present minerals in the composition of conventional aggregates used in paving. The results evaluation of the volumetric composition of the mixtures containing residue indicates that it can use up to 30% of residue in substitution to the conventional aggregates. The evaluation of the mechanical behavior of those mixtures indicates that the residue increment in the studied mixtures caused an increase of the stability and a reduction of the resistance to the traction. The values obtained in the resistance to the traction meet below the minimum value specified by DNIT, but close to the value obtained in the conventional mixture. When taking in consideration the susceptibility of the same ones to the humidity, the results indicate that she can use up to 25% of residue

O principal problema ambiental proveniente dessa atividade é a quantidade de resíduo gerado, cerca de 70% do caulim extraído. Os resíduos são simplesmente amontoados em terrenos das empresas de beneficiamento, ocupando assim uma grande área e causando impacto na flora existente. Quando secos, os resíduos transformam-se em pó e pela ação do vento, se espalham, poluindo o ar. Sendo assim, o presente trabalho tem como objetivo avaliar a incorporação do resíduo grosso, oriundo do beneficiamento de caulim, em substituição parcial de todos os agregados empregados em uma mistura convencional de concreto asfáltico, a qual foi utilizada na pavimentação da BR101/RN061 trecho entre Ponta Negra e Ares. Essa avaliação foi realizada em três etapas. A primeira refere-se à avaliação das características físicas, térmicas e mineralógicas do resíduo com o intuito de classificá-lo e definir sua aplicação como agregado (miúdo e graúdo). A segunda refere-se à caracterização física dos agregados e do material asfáltico utilizados na mistura convencional. E a terceira à avaliação das misturas contendo resíduo, as quais foram elaboradas a partir da mistura convencional com a incorporação gradativa do resíduo, de 5 a 40%, em substituição à parte dos agregados convencionais, de forma a obter curvas granulométricas similares a da mistura convencional. Essa avaliação foi realizada através da comparação entre a composição volumétrica, o comportamento mecânico e a suscetibilidade à umidade das misturas contendo resíduo com os da mistura convencional, e com os das especificações exigidas pelo DNIT. Os resultados mostram que o resíduo grosso oriundo do beneficiamento de caulim possui grãos dos mais variados diâmetros, sendo assim, pode substituir parte de todos os agregados convencionais e do filler em uma mistura asfáltica. Além disso, a sua composição mineralógica apresentou os mesmos minerais presentes na composição de agregados convencionais utilizados em pavimentação. Os resultados da avaliação da composição volumétrica das misturas contendo resíduo indicam que se pode empregar até 30% de resíduo em substituição aos agregados convencionais. A avaliação do comportamento mecânico dessas misturas indicam que o incremento de resíduo nas misturas estudadas ocasionou um aumento da estabilidade e uma redução da resistência à tração. Os valores obtidos na resistência à tração se encontram abaixo do valor mínimo especificado pelo DNIT, mas próximos ao valor obtido na mistura convencional. Ao levar em consideração a suscetibilidade das mesmas à umidade, os resultados indicam que se pode empregar até 25% de resíduoCoordenação de Aperfeiçoamento de Pessoal de Nível Superiorapplication/pdfporUniversidade Federal do Rio Grande do NortePrograma de Pós-graduação em Engenharia SanitáriaUFRNBRSaneamento Ambiental; Meio Ambiente; Recursos Hídricos e HidráulicaBeneficiamento de caulimResíduoConcreto asfálticoKaolin improvementResidueAsphalt concreteCNPQ::ENGENHARIAS::ENGENHARIA SANITARIAIncorporação do resíduo oriundo do beneficiamento de caulim em concreto asfálticoIncorporation of the residue originating from the improvement of kaolin in asphalt concreteinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisinfo:eu-repo/semantics/openAccessreponame:Repositório Institucional da UFRNinstname:Universidade Federal do Rio Grande do Norte (UFRN)instacron:UFRNORIGINALCibeleGC.pdfapplication/pdf1402838https://repositorio.ufrn.br/bitstream/123456789/15945/1/CibeleGC.pdfdb637069ba867fa96c00ae8cf6ff383cMD51TEXTCibeleGC.pdf.txtCibeleGC.pdf.txtExtracted texttext/plain170305https://repositorio.ufrn.br/bitstream/123456789/15945/6/CibeleGC.pdf.txt6f53a5c38fca29d3d2928fa24cf1b504MD56THUMBNAILCibeleGC.pdf.jpgCibeleGC.pdf.jpgIM Thumbnailimage/jpeg2915https://repositorio.ufrn.br/bitstream/123456789/15945/7/CibeleGC.pdf.jpged2f859a572c9b23da0349b57226b441MD57123456789/159452017-11-02 07:10:06.758oai:https://repositorio.ufrn.br:123456789/15945Repositório de PublicaçõesPUBhttp://repositorio.ufrn.br/oai/opendoar:2017-11-02T10:10:06Repositório Institucional da UFRN - Universidade Federal do Rio Grande do Norte (UFRN)false
