Resumo: | Inserting polymers into the asphalt binder can improve rheological properties, making it possible to increase pavement performance and service life. Elastomeric polymers, found in tire rubber and plastomers such as PET, provide beneficial modifications added to the binder. This research aims to perform a comparative analysis of the rheological properties of adding micronized PET and crushed tire rubber to the asphalt binder CAP 50/70, by performing empirical and fundamental rheology tests in order to determine the degree of modification each polymer causes and which one promotes the best performance of the asphalt compound. The content that provided the most favourable results with the use of PET was the content of 8%, while with tire rubber it was observed that the insertion of 5% benefits more the properties of asphalt cement. The results found point to effectiveness in adding the residues to the asphalt binder, although PET showed more interesting gains in the characteristics of the asphalt mass in higher contents, while tyre rubber, even in the lower contents, would tend to decrease the parameters of workability of the coating. |

Los polímeros elastoméricos, que se encuentran en el caucho de los neumáticos y en plastómeros como el PET, proporcionan modificaciones beneficiosas añadidas al aglutinante. Esta investigación tiene como objetivo realizar un análisis comparativo de las propiedades reológicas de la adición de PET micronizado y caucho de neumáticos triturados al ligante de asfalto CAP 50/70, mediante la realización de pruebas reológicas empíricas y fundamentales para determinar el grado de modificación que provoca cada polímero y cuál promueve el mejor rendimiento del compuesto de asfalto. El contenido que proporcionó los resultados más favorables con el uso del PET fue el contenido del 8%, mientras que con el caucho de neumáticos se observó que la inserción del 5% beneficia más las propiedades del cemento asfáltico. Los resultados encontrados apuntan a la eficacia en la adición de los residuos al ligante de asfalto, aunque el PET mostró ganancias más interesantes en las características de la masa de asfalto en los contenidos más altos, mientras que el caucho de neumáticos, incluso en los contenidos más bajos, tendería a disminuir los parámetros de trabajabilidad del revestimiento.A inserção de polímeros ao ligante asfáltico pode melhorar as propriedades reológicas, viabilizando o aumento do desempenho e da vida útil dos pavimentos. Os polímeros elastômeros, encontrados na borracha de pneu e nos plastômeros, como é o caso do PET, proporcionam modificações benéficas adicionados ao ligante. Esta pesquisa tem como objetivo realizar uma análise comparativa das propriedades reológicas da adição de PET micronizado e borracha de pneu triturada ao ligante asfáltico CAP 50/70, através da realização de ensaios de reologia empírica e fundamental, de forma a determinar o grau de modificação que cada polímero provoca e qual deles promove o melhor desempenho da massa asfáltica. O teor que proporcionou os resultados mais favoráveis com a utilização do PET foi o teor de 8%, já com a borracha de pneu observou-se que a inserção de 5% beneficia mais as propriedades do cimento asfáltico. Os resultados encontrados apontam eficácia na adição dos resíduos no ligante asfáltico, embora o PET tenha apresentado ganhos mais interessantes nas características da massa asfáltica em teores mais altos, enquanto a borracha de pneu, mesmo nos menores teores, tenderia à diminuição nos parâmetros de trabalhabilidade do revestimento.Research, Society and Development2020-09-13info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/622310.33448/rsd-v9i9.6223Research, Society and Development; Vol. 9 No. 9; e919996223Research, Society and Development; Vol. 9 Núm. 9; e919996223Research, Society and Development; v. 9 n. 9; e9199962232525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/6223/7196Copyright (c) 2020 Adriano Lopes Gualberto Filho, Damares de Sá Ramalho Neta, Larissa Santana Batista, Nayla Kelly Antunes de Oliveira, Giovanna Feitosa de Limahttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccess Gualberto Filho, Adriano LopesRamalho Neta, Damares de Sá Costa, Daniel BeserraLima, Giovanna Feitosa deBatista, Larissa SantanaOliveira, Nayla Kelly Antunes de2020-09-18T01:42:11Zoai:ojs.pkp.sfu.ca:article/6223Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:29:26.887061Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
