Análise das manifestações patológicas do pavimento em um trecho da Avenida Natalino Faust com a Avenida União da Vitória no município de Francisco Beltrão - PR

Abstract

This study aimed to evaluate the conditions of an urban road segment through visual survey, identification of defects, extent, and classification of severity level, following the Manual of Defects and Maintenance and Rehabilitation Activities in Asphalt Pavements. The results showed the presence of various types of defects, such as cracks, surface wear, deformations, potholes, and old patches executed inadequately. It was found that factors such as pavement aging, poorly executed interventions, and lack of continuous maintenance contributed to the observed deterioration. The use of the decision tree present in the Manual of Defects and Maintenance and Rehabilitation Activities in Asphalt Pavements helped in defining the most appropriate solutions, considering severity, extent, and functional traffic classification. Based on the procedures recommended by the manual used, maintenance and rehabilitation activities such as cracks sealing, surface treatments, deep patching, leveling, and, when necessary, drainage implementation were indicated. The cost estimate for the interventions was carried out, providing a preliminary overview of the values needed for the identified punctual corrections. Therefore, the pavement presents an overall condition ranging from fair to critical, requiring planned maintenance actions and continuous monitoring. The results obtained offer relevant technical support to aid road management decisions, contributing to infrastructure improvement and extending the pavement's lifespan.
