Características geotécnicas e resilientes de solos de taludes ao longo do traçado da Estrada de Ferro Carajás para fins de utilização em infraestrutura de transportes

Infrastructure works require materials that are not always available. Searching for deposits near the construction site and the geotechnical study of the soils are essential. This article analyzes the geotechnical and resilient characteristics of soils originating from ten cut slopes of the Carajas Railway (EFC), between the states of Para and Maranhao (Brazil). The occurrence of soils along this track was investigated, for application purposes in the duplication of the EFC and in future works. Consistency limits, granulometry, compaction, SEM, X-ray spectrometry and Resilience Module (MR) tests were performed, in addition to geotechnical classifications. The presence of fine sandy soils with satisfactory lateritic behavior and MR was identified, which can be used in pavement layers.
