Resumo: | A pavement mechanistic-empirical analysis is based on a pre-designed structure checked for required performance criteria. In case the latter are not met, this structure is modified and reprocessed. In this context, analyzing the effect of variations in project parameters on pavement performance prediction subsidizes a better understanding of results provided by computer programs. The objective of this study is to assess the effect of layer thickness and resilience modulus variations on flexible pavement performance. To do so, performance was estimated for the 20th project year through Elastic Layered System Model 5 (ELSYM5) software and American Association of State Highway and Transportation Officials (AASHTO) Mechanistic-Empirical method (ME). Using multiple regression models for result adjustment and through statistical assessments on regression coefficients calculated, it can be concluded that pavement lifespan consumption, predicted by simulations on ELSYM5, is sensitive to variations in coating and subbase thickness and in subgrade resilience modulus. For AASHTO ME method, predicted values for distresses were significantly sensitive to variations in coating, base and subbase thickness, and in base and subgrade resilience modulus. Comparing both approaches, it is concluded that ELSYM5 can be a viable alternative to the application of a ME pavement design method. |

Si no se cumplen, se modifica y se vuelve a procesar. En este contexto, el análisis del efecto de las variaciones en los parámetros de diseño sobre la predicción del desempeño del pavimento proporciona soporte para una mejor comprensión de los resultados proporcionados por los programas informáticos. El objetivo de este trabajo es evaluar el efecto de las variaciones de espesor y módulo de resiliencia de capas sobre el comportamiento de pavimentos flexibles. Para ello, se realizaron estimaciones de rendimiento utilizando el programa Elastic Layered System Model 5 (ELSYM5) y el método empírico mecanicista (E-M) de American Association of State Highway and Transportation Officials (AASHTO). Utilizando modelos de regresión múltiple para ajustar los resultados y, a través de la evaluación estadística de los coeficientes de regresión obtenidos, se puede concluir que el consumo de la vida útil del pavimento, pronosticado con simulaciones en ELSYM5, es sensible a variaciones en el espesor del pavimento. revestimiento y los módulos de resiliencia de subbase y subrasante. Para el método AASHTO E-M, los valores predichos para los distressos fueron significativamente sensibles a las variaciones en el espesor del recubrimiento, base y subbase y en los módulos de resiliencia de la base y subrasante. De la comparación de los dos enfoques, se concluyó que ELSYM5 puede ser una alternativa viable para la aplicación de un método de diseño de pavimentos E-M.A análise empírico-mecanística de um pavimento parte de uma estrutura pré-dimensionada que é verificada quanto aos critérios de desempenho requeridos. Caso estes não sejam atendidos, essa estrutura é modificada e reprocessada. Neste contexto a análise do efeito das variações nos parâmetros de projeto na previsão do desempenho do pavimento fornece subsídio para uma melhor compreensão dos resultados fornecidos pelos programas computacionais. O objetivo deste trabalho é avaliar o efeito das variações das espessuras e módulos de resiliência das camadas no desempenho dos pavimentos flexíveis. Para tanto, foram feitas estimativas de desempenho utilizando o programa Elastic Layered System Model 5 (ELSYM5) e o método Empírico Mecanístico (E-M) da American Association of State Highway and Transportation Officials (AASHTO). Utilizando modelos de regressão múltipla para o ajuste dos resultados e, pela avaliação estatística dos coeficientes de regressão obtidos, pode-se concluir que o consumo da vida útil do pavimento, previsto com simulações no ELSYM5, é sensível às variações das espessuras do revestimento e da sub-base e dos módulos de resiliência do subleito. Para o método E-M da AASHTO os valores previstos para os defeitos foram significativamente sensíveis às variações das espessuras do revestimento, da base e da sub-base e dos módulos de resiliência da base e do subleito. A partir da comparação das duas abordagens, concluiu-se que o ELSYM5 pode ser uma alternativa viável para a aplicação de um método E-M de dimensionamento de pavimentos.Research, Society and Development2021-07-15info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/1746610.33448/rsd-v10i8.17466Research, Society and Development; Vol. 10 No. 8; e42610817466Research, Society and Development; Vol. 10 Núm. 8; e42610817466Research, Society and Development; v. 10 n. 8; e426108174662525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIenghttps://rsdjournal.org/index.php/rsd/article/view/17466/15646Copyright (c) 2021 Thaís Ferrari Réus; Heliana Barbosa Fontenelehttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessRéus, Thaís Ferrari Fontenele, Heliana Barbosa 2021-08-21T18:46:59Zoai:ojs.pkp.sfu.ca:article/17466Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:37:47.626313Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |

A pavement mechanistic-empirical analysis is based on a pre-designed structure checked for required performance criteria. In case the latter are not met, this structure is modified and reprocessed. In this context, analyzing the effect of variations in project parameters on pavement performance prediction subsidizes a better understanding of results provided by computer programs. The objective of this study is to assess the effect of layer thickness and resilience modulus variations on flexible pavement performance. To do so, performance was estimated for the 20th project year through Elastic Layered System Model 5 (ELSYM5) software and American Association of State Highway and Transportation Officials (AASHTO) Mechanistic-Empirical method (ME). Using multiple regression models for result adjustment and through statistical assessments on regression coefficients calculated, it can be concluded that pavement lifespan consumption, predicted by simulations on ELSYM5, is sensitive to variations in coating and subbase thickness and in subgrade resilience modulus. For AASHTO ME method, predicted values for distresses were significantly sensitive to variations in coating, base and subbase thickness, and in base and subgrade resilience modulus.
