Análise de manifestações patológicas de pavimentos asfálticos em trechos de bairros no município de Paulo Afonso - BA

Abstract

In Brazil, the major mode of tranportation of goods and passengers is by roads, with 60% of all Brazilian goods using the road transport, what makes the country dependent of these roads with good conditions. It's necessary to reset priorities and implement measures that assure the recovery of the economy, the resumption of the job offers and the security in all ways. Therefore it's necessary to improve the quality of our highways, thus reducing the accidents, deaths, fuel consumption and the wear and tear on the vehicles, among other wastes. It's required to define the pathological causes of urban pavement, verifying techniques for characterizing the surface conditions of the pavements, drainage conditions and active traffic. Searching for diagnoses that allow the establishment of the real conditions of the roads conservation, through the realization of visual surveys. Focusing on the position of the public power in the face of the problem. The work seeks to make a visual assessment of the pathological manifestations found in stretches of urban pavements in the city of Paulo Afonso / BA. In order to build a literature review, theoretical and normative references relevant to the case study were addressed. Problems such as pans, cracks, sinking, among other pathological manifestations were identified during the field analysis, which have as main causes, execution and design failures, lack of proper maintenance and poor pavement conservation. As an analysis tool, the SmartIRI smartphone application was used. Developed by Almeida (2018) at the Federal University of Ceará, the application provides values for longitudinal irregularity (IRI), velocity and coordinates of a survey. When using SmartIRI, an answer was obtained regarding the user's comfort when traveling the roads under study: Av. Moxotó, Av. Beira Rio, Rua Campos Sales, Av. do Aeroporto, and Av. Getúlio Vargas. Thus, it was possible to complement the analysis with the results found visually in the field. Among the measured values, there was an average IRI classified as good, that is, 2 ≤ IRI ≤ 4, in all evaluated stretches. Although the results of the application are satisfactory, the regular occurrence of defects was verified through visual inspection, pointing to a need for immediate intervention, especially on Rua Campos Sales, where, according to SmartIRI, 25% of the stretch has regular classification, and on Avenida Beira Rio, where, according to SmartIRI, 15.38% of the stretch is classified as regular.
