Avaliação das condições de superfície do pavimento da rodovia PR-585 no trecho entre Vera Cruz do Oeste e São Pedro do Iguaçu

Abstract

The poor quality of a highway directly affects the comfort and safety conditions of its users, as well as increases the operating costs of vehicles. The present work is about a study on the state of conservation of the surface of the pavement of highway PR- 585, located in the western region of Paraná, between the cities Vera Cruz do Oeste and São Pedro do Iguaçu. Initially, a study on the pavement was carried out, from bibliographies, obtaining its definition, classification and its structure of layers. In addition, defects occurring in asphalt pavements were presented, based on DNIT classification, explaining their possible causes. The research also presented the methods of conservation of the pavements and the components of the highways’s system of drainage, explaining the function of each one. The methodology used is based on Standard DNIT 006/2003 – PRO that consists of an objective evaluation of the flexible and semi-rigid pavements’s surface, and from this, was obtained the Global Severity Index of the highway, which classified it with a very bad concept in its state of conservation. Finally, a general diagnosis of the highway was made, obtaining traffic composition data, rainfall regime and an evaluation of the local drainage system. From this, it was possible to determine the causes of the pathologies, proposing measures for the restoration of the pavement.
