Análise de dimensionamento de pavimento flexível: estudo comparativo de métodos.

Abstract

The paving of roads and highways is essential for better quality road transport of people and goods around the world. The development of technologies for better comfort and durability goes back to the times of Ancient Rome. In Brazil, 60% of freight and passengers are carried on highways, being a country of continent territories, with a diversity of species, pedological and geological, it is of great relevance for the study and separation between the new methods of mechanistic DNIT design which is based on two main criteria of rupture, the method being updated in Brazil, and the method of empirical design adopted by the DNER, applied in the 1960s by the engineer Murillo Lopes de Souza, in which the capacity of support of subbed, as measured by the CBR. The present work has owned the objective of analyzing, dimensioning and comparing the methods of sizing exchange rate indicators, with the help of data from the Pavement Engineering Laboratory-LEP / UFCG, Campina Grande-PB, on the PB-138 linking Campina Grande / Catolé de Boa Vista-PB to Boa Vista-PB.With the help of the data, it was possible to size the pavement with the aid of the MeDiNa program and to carry out a comparison between the two sizing methods
