Caracterização geotécnica do solo de Delmiro Gouveia - AL aplicado na pavimentação rodoviária

Abstract

In this work the methodologies of the traditional geotechnical classification to the soil of the region in the hinterland of the state of Alagoas, more precisely in the city of Delmiro Gouveia, are applied, with the objective of identifying its application in the road paving, through geotechnical test results. The analyzed soil was used in an excerpt of the work of the ring road in the same city of the material collection. The study also made it possible to determine the characteristics of the material in terms of granulometry, compaction and resistance of the material related to the CBR value. Thus, the results of the tests made it possible to define the soil characteristics as well graded sand, with variations only in the percentage of boulders and in the fine particles of some samples, respectively. The samples were also classified in the SUCS according to their granulometry and presented similar results as a silt sand, that is, mixing sand with fine particles. In addition, it presented an excellent resistance for use in the paving, being able to be used in several layers as well as in any type of pavement, being it flexible or rigid. Finally, this work allowed the geotechnical characterization of the local soil with indications of which types of layers can be applied to the road paving. In addition, it is important to mention that this type of material can be used in works in the region, considering the good quality and distance of the deposits.
