ANÁLISE PATOLÓGICA DE PAVIMENTO FLEXÍVEL DA BR-163/PR SUB-TRECHO BARRACÃO/PR - SANTO ANTÔNIO DO SUDOESTE/PR

Abstract

Pavement is essential to ensure adequate trafficability in any weather condition throughout all seasons of the year. A safe pavement structure must be designed to distribute the stresses induced by vehicle traffic, as natural soil alone cannot withstand such loads without degrading. Road infrastructure is crucial for efficiently transporting materials and essential supplies that support urban and rural demands. Given the current state of Brazil's infrastructure, it is evident that many of our highways show signs of advanced physical obstacles. This is exacerbated by the significant increase in vehicle fleets and the lack of effective actions for rehabilitating and strengthening the road network. These conditions lead to a progressive increase in pavement pathologies, emphasizing the need for technical interventions beyond routine maintenance. Therefore, monitoring and analyzing the pathologies that may arise over time from pavement use becomes essential. This study aims to diagnose the pathologies manifested in the surface layer of the flexible pavement of BR-163 Highway (Paraná) – Segment: Barracão/PR km 10 – Santo Antônio do Sudoeste/PR km 35. Using the VSA (Value of Current Serviceability) methodology, the objective is to systematize, detail, and quantify the main non-conformities observed in the pavement structure.
