Comparativo entre pavimento flexível e rígido em restauração de trecho da Avenida Tupi, Pato Branco - PR

Abstract

The pavement deteriorates over time due to the action of traffic and weathering, associated with a lack of maintenance. Thus, during the pavement's design life, defects emerge, which may stem from structural issues. The severity of these defects can impact and compromise the functionality of the road, affecting users in terms of comfort and safety during its use. This study aims to analyze methods for restoring a deteriorated flexible pavement and as alternatives, the execution of resurfacing with both flexible and rigid pavements for a section of Tupi Avenue, Pato Branco Paraná. Initially, the existing traffic volume at the location was surveyed, the structural condition was assessed, and the subgrade soil was characterized through specific tests. Additionally, the pavement condition was defined based on data from previous studies. Subsequently, pavement designs for the proposed alternatives were carried out according to current standards and manuals. For comparison between the two alternatives, respective cost spreadsheets were prepared. The analyses and results obtained in this research demonstrate aspects that can aid in decisionmaking for choosing the restoration of the avenue in Pato Branco, PR, identifying factors influencing the selection of the most suitable method for urban road restoration in terms of technical and economic viability, proposing the best restoration method for the studied road.
