Avaliação dos métodos de dimensionamento de pavimentos asfálticos, intertravados e com concreto: previsões de comportamento.

Abstract

This work realized the dimensioning of the pavement superstructure for structures with revestiment in bituminous concrete hot machined, in interlocking concrete blocks and in simple concrete slabs given the same contour conditions. through semi-empirical dimensioning models or mechanistic models that disregard some relevant aspect. Were used this models of dimensioning: Souza (1981) for asphaltic pavements, PMSP (2004a) for interlocking pavements e PCA (1984) for concrete pavements. So, proceeded for the realization of the mechanist verification about the main models of ruin of each dimensioning, considering aspects that were ignored in the dimensioning. When identified that the dimensioning of the superstructure don't attend the project traffic volume, an adequate superstructure was sought to meet the mechanistic criteria adopted, only alternating the thickness of the coating. It was found that for the situation analyzed the pavement with revestiment of hot-machined bituminous concrete and with simple concrete slabs presented early ruin due to the fatigue of the coating.
