ESTUDO DE ANTEPROJETO PARA DIMENSIONAMENTO DO PAVIMENTO FLEXÍVEL POR MEIO DA AVALIAÇÃO SUPERFICIAL DAS PATOLOGIAS DA AVENIDA AYRTON SENNA LOCALIZADA EM POUSO ALEGRE - MG

Abstract

The main focus of this work is to diagnose the flexible pavement of Avenida Ayrton Senna, located in Pouso Alegre - MG, determining its quality of traffic and serviceability. The study was carried out by the superficial pathology analysis method, since it is necessary to guarantee the quality of displacement and safety for the users of this stretch. Proposals for the solution of the exposed problem include techniques for the recovery of existing pavement and a proposal for dimensioning a new flexible pavement, taking as preliminary design parameters the average volume of vehicles that use the road. The road, object of study, consists of a stretch about 4.7 km long and is of great importance for the city, being responsible for the diversion of heavy vehicle traffic from the urban center. Using the Current Servant Value (VSA) method, in which the pavement is rated with a score from 0 to 5, eight stretches of about 500 meters each were diagnosed, including those that show greater degradation due to lack of maintenance. Using photographic reports, it was possible to catalog and diagnose the current situation of the stretch, in which it was observed the need to perform corrective maintenance processes as a short-term measure and asphalt pavement restoration as a long-term measure.
