ESTUDO COMPARATIVO ENTRE O MÉTODO DE DIMENSIONAMENTO DO DEPARTAMENTO NACIONAL DE ESTRADAS DE RODAGEM (DNER) E O MÉTODO MECANÍSTICO-EMPÍRICO MEDINA

Abstract

he process of infrastructure development, particularly concerning highways, represents one of the most significant priorities for a country. In Brazil, the road transport mode takes a prominent position, being not only the most demanded but also the most significant. For this reason, the creation and maintenance of high-quality roads with suitable traffic conditions become imperative to ensure comfort and safety for users. In this context, the adaptation of sizing methods becomes crucial to guarantee the durability of roads as established in projects.The DNER Method has played a fundamental role in sizing Brazilian roads over the years. However, faced with substantial growth in the road sector, new techniques and methods became necessary, leading to the emergence of the Mechanistic-Empirical National Pavement Sizing Method (MeDiNa) in 2014. This method is based on a homonymous software and was proposed by the National Department of Transport Infrastructure (DNIT). This study aims to make a comparison between the traditional DNER method and the innovative Mechanistic-Empirical National Pavement Sizing Method (MeDiNa). The objective is to compare the two methods, analyzing which one provides more suitable sizing for the proposed design period of 20 years. These methods will be applied to the GO-156 highway in the urban areas of the cities of Anicuns-GO and Americano do Brasil-GO. The data used are provided by the Goiás State Infrastructure and Transportation Agency (GOINFRA)
