Avaliação das condições de superfície de pavimentos rodoviários por meio do VSA e do IRI obtido por aplicativo para smartphones

Abstract

The traditional International Roughness Index (IRI) evaluation generally requires high-cost equipment, making the functional assessment costly and slow. As a result, the use of smartphones applications may be an economic and fast alternative of longitudinal irregularity obtainment. This study has the aim of comparing IRI data acquired through a smartphone application to the Current Service Value (VSA) which is a subjective assessment of paved roads, defined by the National Department of Transportation Infrastructure (DNIT). The study also compares the results to retroactive data in order to understand the changes in road quality by maintenance operations. The studied segment presented VSA between optimal and regular and IRI between regular and poor, with strong correlation between the parameters.
