Avaliação, diagnóstico e sugestões de recuperação para pavimento asfáltico em um trecho do corredor de ônibus da Av. Nevaldo Rocha, em Natal/RN

Abstract

This work aims to evaluate, diagnose and suggest recovery and maintenance techniques for the flexible pavement lanes in a strech of the Avenue Nevaldo Rocha – Natal/RN. Being one of the most important for the city, the highway has been continuously suffering deteriorization and defects due to the effect of weariness, weather and loads. The evaluation methodology consists of visual inspection and evaluation proposed by the Central Laboratory of Bridges and Roads (LCPC) based on the use of the VIZIR method. The results show images of some defects found and the calculation of the surface deterioration index (IS) for both lanes, as well as their conceptualization. In the discussion section, problems not foreseen in the norm are identified and maintenance and recovery techniques are suggested for the evaluated pavements.
