Análise técnico-financeira da execução das camadas de base e sub-base em pavimentos flexíveis

Abstract

This study analyzes the financial impact resulting from inadequate compaction of the base and sub-base layers of five highways built in the state of Ceará. The research quantifies the unforeseen financial losses in the budget due to the need for corrections in highway sections that did not meet the necessary specifications required by the projects. The methodology used to assess compaction quality was based on compliance verification standards established by DNIT regulations regarding the compaction of embankments and granulometrically stabilized bases. By evaluating the degree of compaction in relation to normative standards, the results indicated failures in the compaction process, requiring corrective interventions that increased construction costs, directly impacting the highway construction budget. Highways that underwent a well-executed compaction process did not experience cost increases, whereas those with verification failures saw increased construction costs, causing financial losses for the responsible companies and, consequently, for the state. It is worth noting that a deficient construction process leads to early structural pathologies in pavement structures. Thus, this study reinforces the importance of strict quality control in compaction to prevent financial waste and ensure the safety and durability of a highway.
