The prefectures in general, including in Tucuruí (PA), have faced increasing challenges in
relation to the conservation of urban roads, requiring the development and application of
modern systems of management and maintenance. A pavement management system (SGP) is
able to coordinate a set of activities aimed at maintaining pavements in functional and
structural conditions suitable to the needs of its users, providing a good infrastructure for
economic and social development. This work aims to show, through literature review and
field research, a preliminary experiment data collection about defects in floors in order to
support the implementation of a GSP, subjective analysis, in order to analyze and detect
defects in asphalt coatings in the floors of these roads, to then propose measures of
maintenance and rehabilitation of pavements of streets and avenues of the neighborhoodThis
pioneering work, as regards the assessment of the condition of the Tucuruí floors. The need
for implementation of a new management system in maintenance, occurred in function of the
evolution of cities as population issues and the number of vehicles that travel daily by their
routes, as well as the need for safety, quality and low cost. 33-way were evaluated in field
research, and on all roads in the neighborhood were found to be free of defects in floor
coverings, and in all the streets, except the street of lilies, will require maintenance and
rehabilitation activities. The most frequent defect was present in 29 material spill, which
corresponds to 87.8% from total; the second most frequent defect was pot or hole in 27, which
corresponds to 81.8% of total and the third most frequent defect was interconnected shrinkage
crack or reflection on 21 routes, which corresponds to 63.6%. On the basis of data about
defects in floors from field research and considering the proposed decision trees by Fernandes
Jr. and Pantigoso (1998), the type of maintenance activity and more frequent rehabilitation
will be patch which will be applied in 29, which corresponds to total 87.9%; the second most
frequent activity will be drainage, which will be applied in developing the district 24 Cohab,
which corresponds to the total and 72.7% the third most frequent activity will be sealant,
which will be applied in 22 neighborhood routes Cohab, 66.7%. In general the routes Cohab
feature large number of defects, reflecting a bad state of repair of flexible pavements, which
generated a large amount of proposals for maintenance activities and rehabilitation of
pavements which justifies the adoption of a more precise SGP in Tucuruí.
