Resumo: | The use of recycled materials can become a constructive application with good acceptance in the road sector, and is a great contribution to the sustainability policy. In this scenario, the study of economic and sustainable techniques for execution, construction and maintenance of highways, forces a survey in which they can find alternatives to the use of materials that reduce energy consumption, taking into account also the environmental appeal. Therefore, this is an objective research on the study of a way to use, reuse, and improve the use of the recycled asphalt pavement (RAP) in hot asphalt mixtures. This is possible due to the RAP's recycling process being a viable option to replace conventional pavement materials. Then, the RAP becomes an alternative when someone wishes to improve the properties of a material, called particle size stabilization, aiming at a correct particle size and obtain a material with greater strength, efficiency and lower cost. To achieve the purpose of this study, laboratory tests were made to evaluate the mechanical properties and adhesiveness of mixtures containing 10% addition of RAP, 20% and 30%, compared to a reference mix without the RAP addition. Additionally, the initial use of the Bailey method was an important factor to the formation of the mixtures and selection of the aggregates used to Superpave methodology to design dosage strength and preparing of the samples. For mechanical evaluation were used resilient modulus tests (RM) and to review viscoelastic were used uniaxial dynamic modulus test. In addition, the indirect tensile strength tests were performed (RT) and Flow Number (FN) and damage tests induced moisture through the Modified Lottman test and wear a Cantabro abrasion, for evaluation of the properties of adhesion and cohesion of the mixtures, respectively. So after obtained these results, it was possible to make an analysis of the use of these hot mix asphalt recycling hot pavements, as well as assess how much conventional mixtures can be improved with the inclusion of recycled material, replacing virgin aggregate. Then, it was possible to infer that the mechanical evaluation showed positive results with the addition of RAP compared to a reference blend. It´s possible to reduce the new binder content between 13 and 37%. The results showed that RM stiffness and indirect tensile strength increases with RAP amount. Furthermore, the FN test results showed reductions on permanent deformation and rutting of the RAP´s mixtures. Through the master curve obtained by dynamic module, along with modeling 2S2P1D, it was found that the CAF10 mixture unexpectedly had stiffness greater than the CAF20 mixture, which has 20% more RAP than the previous. |

Com isso, torna-se viável o estudo de técnicas econômicas e sustentáveis para execução, construção e manutenção de rodovias, forçando uma pesquisa em que se possa encontrar alternativas para o uso de materiais que diminuam o consumo de energia, levando em conta, ainda, o apelo ambiental. Por isso, essa pesquisa se objetiva no estudo de uma maneira de utilizar, reutilizar e melhor aproveitar o material fresado em misturas asfálticas a quente. Isto se dá devido ao processo de reciclagem deste material ser uma alternativa de possível substituição aos materiais convencionais naturais de pavimentação como, por exemplo, a pedra britada. Então, o material asfáltico do pavimento deteriorado (fresado) torna-se uma das alternativas quando se deseja melhorar as propriedades de um material, denominada estabilização granulométrica, visando corrigir sua granulometria e obter um material com maior resistência, eficiência e menor custo. Para atingir o objetivo desta pesquisa, foram realizados ensaios laboratoriais que pudessem avaliar as propriedades mecânicas e de adesividade das misturas contendo 10% de adição de fresado, 20% e 30%, comparadas a uma mistura de referência sem adição de agregado reciclado. Além disso, a utilização inicial do Método Bailey foi um fator importante para a formação das misturas e seleção dos agregados, sendo utilizada a metodologia Superpave para dosagem do teor de projeto e moldagem das amostras. Para avaliação mecânica, foram usados ensaios de módulo de resiliência (MR) e, ainda, para avaliação viscoelástica, ensaio de módulo dinâmico uniaxial. Além destes, foram realizados ensaios de resistência à tração indireta (RT) e Flow Number (FN) e, também, ensaios de dano por umidade induzida, através do ensaio de Lottman Modificado, e desgaste por abrasão Cântabro, para avaliação das propriedades de adesividade e coesão das misturas, respectivamente. Assim, após obtidos estes resultados, foi possível efetuar uma análise da utilização destas misturas asfálticas na reciclagem a quente de pavimentos, bem como avaliar o quanto as misturas convencionais podem ser melhoradas com a inserção de material reciclado, em substituição ao agregado virgem. Então, foi possível concluir que a avaliação mecânica apresentou resultados positivos com a adição de fresado, quando comparados a uma mistura de referência. Os resultados de MR mostraram que a rigidez aumenta ao passo que a quantidade de fresado é maior na composição das misturas, o mesmo foi possível verificar através dos ensaios de RT, os quais apresentaram valores crescentes. Além disso, o ensaio de FN comprovou que o fresado aumenta a rigidez das misturas. Através da curva mestra obtida pelo módulo dinâmico, juntamente com a modelagem 2S2P1D, foi possível constatar que a mistura CAF10, inesperadamente, apresentou rigidez maior que a mistura CAF20, a qual tem 20% a mais de fresado que a anterior.Fundação de Amparo a Pesquisa no Estado do Rio Grande do Sulapplication/pdfporUniversidade Federal de Santa MariaPrograma de Pós-Graduação em Engenharia CivilUFSMBREngenharia CivilPavimentaçãoReciclagem a quenteFresadoMódulo dinâmico2S2P1DPavingHMARAPDynamic modulus2S2P1DCNPQ::ENGENHARIAS::ENGENHARIA CIVILEstudo laboratorial da utilização de material fresado em misturas asfálticas recicladas a quenteLaboratory study using rap in recycling hot mixinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisSpecht, Luciano Pivotohttp://lattes.cnpq.br/8038412953408618Pinheiro, Rinaldo Jose Barbosahttp://lattes.cnpq.br/1539316781096410Nascimento, Luis Alberto Herrmann dohttp://lattes.cnpq.br/4899301992358051Pereira, Deividi da Silvahttp://lattes.cnpq.br/9639329922610388http://lattes.cnpq.br/0089039958175024Centofante, Roberta3001000000034003003003003003008ec440eb-7c63-4e2e-8cd0-a61f73b7ab5d132c0208-d9c7-49e2-8ca0-6971d12a9c38a539ebc7-a450-4588-a235-904b57a877fe1a1397da-777b-4576-bfde-6f0208dd12f8d96ee26c-775a-45bd-8b59-eeee070e8af5info:eu-repo/semantics/openAccessreponame:Biblioteca Digital de Teses e Dissertações do UFSMinstname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMORIGINALCENTOFANTE, ROBERTA.pdfapplication/pdf4190502http://repositorio.ufsm.br/bitstream/1/7915/1/CENTOFANTE%2c%20ROBERTA.pdf8a3bbd1d546897cc857f656412379616MD51TEXTCENTOFANTE, ROBERTA.pdf.txtCENTOFANTE, ROBERTA.pdf.txtExtracted texttext/plain281294http://repositorio.ufsm.br/bitstream/1/7915/2/CENTOFANTE%2c%20ROBERTA.pdf.txtf0c772b3daac5135f94335317e15f337MD52THUMBNAILCENTOFANTE, ROBERTA.pdf.jpgCENTOFANTE, ROBERTA.pdf.jpgIM Thumbnailimage/jpeg4330http://repositorio.ufsm.br/bitstream/1/7915/3/CENTOFANTE%2c%20ROBERTA.pdf.jpg12ed52fb4b4163d9e24ab46941ba5c4cMD531/79152022-01-12 08:49:41.239oai:repositorio.ufsm.br:1/7915Biblioteca Digital de Teses e Dissertaçõeshttps://repositorio.ufsm.br/ONGhttps://repositorio.ufsm.br/oai/requestatendimento.sib@ufsm.br||tedebc@gmail.comopendoar:2022-01-12T11:49:41Biblioteca Digital de Teses e Dissertações do UFSM - Universidade Federal de Santa Maria (UFSM)false |
