Análise comparativa entre o método empírico do DNIT e o método mecanístico-empírico (MEDINA) para dimensionamento de pavimentos flexíveis

Abstract

The study compares the dimensioning of flexible pavements using the empirical DNIT method and the mechanistic-empirical MeDiNa software, applied to the Caueiras Access Highway (PE). The original design, based on the DNIT method, showed undersizing of the pavement and base layers, indicating a risk of compromising durability. The MeDiNa software confirmed this analysis and enabled a more accurate assessment of the structural behavior, considering traffic and material properties. The study reinforces the importance of mechanistic-empirical analysis for optimized dimensioning, ensuring more durable, safe, and economical pavements.
