Aplicação do método IGG - Índice de Gravidade Global - para avaliação e determinação de serviços de reabilitação de pavimentos flexíveis. Estudo de caso: rua 01 da Universidade Federal do Amapá- Campus Marco Zero

Abstract

It is common for flexible flooring to suffer deterioration over time, having an average service life stipulated around 10 years, when combined with appropriate preventive maintenance processes. In this way, over time, various types of pathological manifestations can emerge that impair the conditions of the existing floor. The present work uses the IGG Method (Global Gravity Index) to analyze the conditions of the flooring of Rua 01, Federal University of Amapá, with three years of use. This method objectively evaluates the types of pathological manifestations of the floors existing in the pathway and their repetition index, so that it is possible to characterize the conditions of the floor. Through the analysis of the results obtained, it was possible to identify that the most common defects are surface wear, longitudinal slits, transverse slices, block slits, and wheel-rail sinking, characterizing the floor with the bad concept. From the diagnosis of the functional condition of the studied floor, it is suggested some preventive and corrective interventions based on the technical prescriptions of the Manual of Restoration of Asphaltic Floors - DNIT, such as sealing coating and asphaltic overlaying in some sections, to increase the life of the floor taking into account the cost-benefit ratio. The use of the IGG Method presented a functional classification of the path in accordance with its state of conservation and consequently for adopting the corrective solution.
