Análise comparativa de custo entre pavimentos de concreto de cimento portland, blocos intertravados e concreto asfáltico

Abstract

This study identified a stretch of highway in the municipality of Alegrete/RS that through observation and application of methods of counting and classification of vehicles was possible to perform the analysis and the design of floor coverings such as different asphalt concrete , interlocking blocks and concrete Portland cement , determining the unit cost of their materials and execution, with a view to comparison and obtaining the pavement which generate lower cost serving a life span of ten years for highway , taking into account the growing number of vehicle 3% as indicated by the DNIT in traffic studies Manual. Systems were used SICRO II and SINAPI to obtain unit costs and end of each project, determined for one kilometer, being possible the use of these indices in other paving studies that also involve different materials , sizing techniques and costs. After conducting studies , it appears that financially the pavement interlocking blocks meet the design requirements and features more attractive to implement when compared to the cost of execution of asphaltic concrete pavement and Portland cement concrete.
