Análise de desempenho funcional de pavimentos flexíveis em condomínios residenciais na cidade de São Luís - MA

Abstract

The importance of paving dates back to the early days of humanity, always evolving alongside innovations and improving mobility technologies. Pavements are divided into three types: flexible, rigid, and semi-rigid. Each type consists of distinct structural and surface layers and is evaluated in terms of functionality, structure, and safety. Each type has its own defects and potential causes. The methodology of this work included a literature review and bibliographic research, as well as field surveys to assess the superficial degree of degradation of the pavements. The study of the superficial evaluation of pavements was carried out through the calculation of the Global Severity Index (IGG), based on the DNIT 006/2003 – PRO standard. The research was conducted in two residential condominiums in São Luís-MA, where the conditions of two types of pavements were analyzed: asphalt and interlocking blocks. With the collected data, the main surface pathologies occurring in these pavements were analyzed. In the asphalt pavement, the most common pathology was wear, at 40%, while in the interlocking pavement, it was short isolated transverse cracks, at 57%. The application of the superficial evaluation method of the Global Severity Index resulted in a final classification of "Regular" for the asphalt pavement and "Poor" for the interlocking pavement. Therefore, the importance of evaluation methods was recognized as they help to understand the causes, apply practical methods, and seek possible interventions for the identified pathologies. It was proposed that for Condominium A, crack sealing could be used, along with the application of a sealing layer with asphalt emulsion in some areas, patching, and a recomposition with asphalt micro-surfacing. For Condominium B, superficial defects can be resolved by replacing damaged blocks and re-grouting new pieces, while structural defects require the replacement of granular material in the base, compaction, and repaving of the affected area
