Master's degree in civil engineering from the Federal University of Rio Grande do Norte (2015), currently holds a PhD in Geotechnics at the University of Brasília. He is a professor at the Federal Institute of Education, Science and Technology of Goiás. He has experience in Civil Engineering, with emphasis on Environmental Geotechnics, Applied Geotechnics for Mining and Pavement, mainly in the following areas: tailings dams, stability, laboratory tests , geotechnical and technological characterization of soils, industrial and mining residues, recycling and reuse of waste and management of pavements. He has published several national and international works around the world.



Mining in Brazil plays a fundamental role in the economic and social development of the country, contributing directly to the improvement of the population's life. However, the mining activity may cause harm to the environment. In this context, it is appropriate to highlight the visual pollution caused by the storage of waste in the open. Among the various alternative ways of mitigating the environmental impacts caused by mining is the use of waste from mineral extraction activities in Civil Engineering works, especially those related to the construction of landfills, by using large volumes of material. The application in layers that will compose pavement structures of the highways is, therefore, among the options of great viability for application of mining residues. However, the geotechnical properties of these materials need to be investigated, even when mixed with natural soils. From these aspects, the present research proposes a feasibility study of the waste from the beneficiation of the iron ore, due to the mining activity in the municipality of Jucurutu, in the state of Rio Grande do Norte - Brazil, where the mechanical behavior of the material, by means of geotechnical laboratory and field tests. The iron ore residues were stabilized with a granular soil from the region, which has been used by the municipality of Jucurutu-RN in the construction of roads. According to the results obtained the residue from the processing of iron ore has technical and economic feasibility to be used in road works.
