Avaliação Subjetiva da Condição do Pavimento Flexível de Subtrechos de uma via da Cidade de Barreiras-Ba

Abstract

The study of the surface quality of the pavement is of fundamental importance, since it allows determining the state in which it is located and allows better use of the available resources. In addition to allowing the recognition of sections of the road that require improvements and that must be prioritized. This research aims to subjectively analyze the surface condition of flexible pavement using the current service value (VSA) method, with the help of a visual scale built based on the proposal of Oliveira et al. (2013). The VSA analysis on Rua Capitão Manoel Miranda, located in the center of Barreiras, was carried out considering two different times of the day, with the aim of observing how different temperature and humidity conditions interfere with the comfort and smoothness of the trip offered to the users. The road was divided into four subsections of 600 meters each, totaling 2.4 kilometers. The surface of the road under study was classified as “good” after analyzing photographs using the visual scale and “fair” through the VSA evaluation. Once the final VSA (2.54) determined for the track was close to the accepted limit, it indicates the need to perform corrective maintenance and, subsequently, periodic preventive maintenance.
