Avaliação funcional e estrutural das marginais PR-840

Abstract

Asphalt pavement is an integral part of a municipality, state, and country's infrastructure as it provides safety and comfort to users and facilitates mobility. Like any construction, pavement also requires periodic maintenance to continue serving users effectively. When the road is compromised, it is necessary to conduct evaluations followed by reinforcement projects, applying surface corrections and increasing structural capacity to withstand new traffic demands. The objective of this work is to perform a functional and structural evaluation of the flexible pavement on the margins of the PR-840 highway, divided into 2 homogeneous two-way segments, located in the city of Campo Mourão. The functional evaluation involved a detailed inventory of the road's condition, including data collection to calculate the Pavement Management Index. The functional evaluation provided crucial information about the current state of the pavement, identifying areas that require intervention, resulting in a poor rating for both segments. Additionally, a structural evaluation of the pavement was conducted through Benkelman Beam tests, essential to determine the pavement's load-bearing capacity and its ability to support current and future traffic. The results revealed high deflections and low curvature radii for segment 1, while segment 2 showed low deflections and a high curvature radius. It was concluded that the structural quality of the pavement was deemed regular, and reinforcement solutions were proposed as corrective measures for both segments.
