Degradação no pavimento demandada por veículos de carga, em trecho da Av. Gen. Rodrigo Otávio Ramos, na cidade de Manaus -AM

Abstract

The movement of goods and products is a fundamental activity for the development of urban centers. The road transport mode plays a significant role in the mobility of people and the shipment of goods, accounting for 61% of cargo transportation and 95% of passenger transportation. Given the importance of this activity for the economy and regional growth, it is necessary to have a well-developed infrastructure capable of meeting the demand. The objective of this study is to identify and characterize the deteriorations along a 4,700-meter stretch of Rodrigo Otávio Jordão Ramos Avenue, comparing remote sensing data with field surveys to evaluate the impacts of these deteriorations on local urban mobility. The identification of deteriorations was conducted through visual inspection using Google Earth, as well as in-field assessments, following the methodologies outlined in DNIT Standards 005/2003 and 006/2003. An inventory of observed deteriorations was performed at each station to assess the pavement conditions, and then compared with remote images of the corresponding locations to determine the incidence and quantify these pathologies.To understand the flow of commercial vehicles, an empirical observation method was employed to assess and quantify the flow of cargo vehicles on the studied road. It was observed that a total of 44 defects were found along the entire length of the route, with the highest incidence being potholes (20%), followed by patches (11%), and alligator cracking (11%). As for the vehicle flow, an average of 130 vehicles per hour was estimated for the segment. The comparison between on-site defects and remote observations led to the conclusion that the poor pavement quality and the high presence and progression of defects in 2020 necessitated a road resurfacing intervention in 2022. Therefore, the occurrences of these pathologies, which directly impair urban mobility, were directly related to the road transportation infrastructure, vehicle operating costs, increased traffic accidents, and environmental impacts.
