Análise Comparativa entre Pavimento de Concreto X Pavimento Flexível Estudo de Caso: Implantação da Rodovia MS-380 (Município de Ponta Porã - MS)

Abstract

This study aims to present comparisons between economic viability and structural performance for two alternatives in pavement implementation: Rigid Pavement (cement-concrete) and Flexible Pavement (CBUQ). The solutions analyzed were based on surveys, studies, and tests conducted for the Pavement Project of MS-380 Highway, located between the junction with BR-163 and MS-164, in the municipality of Ponta Porã – MS. Two comparisons were conducted, the first focusing on economic viability and the second on structural performance. The cost analysis began with quantity surveys, and budget compositions were based on the Reference Cost System for Construction Works – SICRO. The conclusion drawn was that the Rigid Pavement solution exhibited greater economic viability. Simultaneously, the analysis of structural performance examined the behavior of both alternatives, considering proposed traffic growth on the highway. It concurrently recorded the behavior of structural limitations (stresses, deformations, deflections, fatigue consumption, and erosion), comparing the results with various reference sources. The final analysis indicates that the Rigid Pavement alternative will have superior durability and structural performance following the proposed traffic growth.
