Análise do índice de condição do pavimento em uma via urbana destinada para corredor de ônibus na cidade de Caxias do Sul/RS

Abstract

Rigid pavements in Brazil have been receiving more attention in recent years, becoming increasingly necessary especially on roads with incense and heavy traffic. Despite its high initial cost, its use can be an economical solution in front of flexible pavements, especially when maintenance and road maintenance costs. This work was carried out in the bus corridors of Moreira César, Pio XII and Rossetti avenues in the city of Caxias do Sul, which was paved with the use of a flexible replica at least in 2016 in order to ensure better and longer lasting. comfort and safety conditions to local traffic. The objective of this study was to analyze the current conditions of the pavement in question by calculating the Pavement Condition Index (PCI), according to DNIT guidelines for the analysis of pavement quality performed on site and from studies already performed. In this way, the results obtained were compared to the previous results, allowing an overview of the pavement quality variation until then and allowing to determine the first points of a performance curve. Upon inspection of the labels, these signs of degradation were discovered, ie expected as no maintenance has been done in the last 3 years. Despite many pathologies identified in visual inspection, in general, not exhibiting pathological manifestations with high severity, the pavement being evaluated with a high concept of PCI assessment. The regression curve also showed satisfactory results, but it is recommended that further checks be performed, allowing monitoring of the evolution of pavement conditions and adjusting a deterioration curve to a more accurate condition of the analyzed bus corridor (sic).
