PROPOSIÇÃO DE UMA SOLUÇÃO DE RECUPERAÇÃO FUNCIONAL DO PAVIMENTO FLEXÍVEL DA RODOVIA BR-267, TRECHO DE CAXAMBU/MG AO ENTRONCAMENTO COM CONCEIÇÃO DO RIO VERDE/MG

Abstract

This work analyzes the superficial pathologies of the flexible pavement of the Highway BR-267 Excerpt: Caxambu / MG - Entroncamento Conceição Do Rio Verde / MG, using the Current Service Value method – CSV. The purpose of this study is to identify and classify the various types of existing pathologies, and thus to perform an effective monitoring of pavement condition, proposing whenever necessary, the intervention of the type of restoration, since it is more economical than the intervention of the type reconstruction. The average score found in the evaluation of the floor by the CSV was 2.40, showing that the section is at a level below acceptability, but above the traffic limit. Building on the historical series of AADV (Annual Average Daily Volume) it was possible to find the growth rate, and thus determine the future traffic for the year 2027, allowing a correct and efficient design for new asphalt coating, through the number "N". It was evidenced that the road presents several pathologies, and they must be remedied, before the situation of the pavement worsens. The service of the type cold milling, is important, because it eliminates the superficial pathologies found, the new asphalt coating chosen was Concrete, Bituminous, Hot Machined (CBHM), due to the ease of plant and field in the region, allied with the speed in the execution process, the thickness found through the calculations was of 5,0 centimeters, guaranteeing the life of the new pavement in 10 years.
