Estudo de execução de pavimentação em trecho urbano

Abstract

The objective of this study was to describe the pavement rehabilitation stages, including earthworks, soil improvement, and the asphalt paving layer. Improvements were made to five streets, carefully selecting the most appropriate material for each specific situation to minimize costs and meet specifications. The street chosen for analysis was the 1st Crossing of Ribeiro Pessoa Street. The execution and supervision of the soil improvement work, as well as the application of the Hot Mix Asphalt Concrete (HMBC) and the asphalt overlay, were monitored. This study used the earthmoving method in accordance with the guidelines of the National Department of Transportation Infrastructure (DNIT). This procedure involves essential steps to prevent potential future consequences, such as soil erosion and infiltration. Some challenges were encountered, one of the main ones being the incompatibility of the soil with the solution specified in the bidding process, resulting in significant financial and schedule impacts.
