Estudo das manifestações patológicas de pavimento flexível em um trecho da rua Balbina de Matos na cidade de Dourados/MS

Abstract

The pavement is a superstructure formed by layers composed of materials combined to resist the efforts and calculations dimensioned for the road traffic. However, due to several factors, the paving can suffer pathological manifestations. The present study seeks to analyze qualitatively and quantitatively the conditions of a section of Rua Balbina de Matos, Dourados-MS, a connection route to the university region of the city. The research was carried out using the Norms DNIT 005/2003 – TER, DNIT 006/2003 – PRO and DNIT 009/2003 – PRO. Based on the standard defect terminology, it is possible to visually analyze the pathological manifestations found, allowing their quantification. With the use of Norm DNIT 006/2003 – PRO and the use of data collected on the road, an objective evaluation method was applied using the Global Gravity Index – GGI – which indicates whether the state of conservation of the pavement is excellent, good, regular, bad or very bad. Through the study carried out, it was verified that the section in question presents a GGI value corresponding to the concept of poor conservation, presenting several pathological manifestations, such as pans, fissures, interconnected and individual cracks and plastic foundation, which infers the need to implement improvements in order to obtain a road with good rolling condition, safety and economy for the user.
