Resumo: dc.description.abstractThis experimental research aims to analyze the permanent deformation of three tropical soils, in a triaxial apparatus of cyclic loading, using increasing loads in multistage. For this test, three soils from the BR-040 right-of-way were used (Km 06: A-7-5, Km 26: A-1-b and Km 824: A-2-4). After classifying the material, two specimens were molded at normal compaction energy (at optimal and optimal humidity +2%), totaling six specimens. The permanent deformation test was carried out according to the multistage loading technique, which considerably reduced laboratory time and the amount of material used. The results indicate that the soil at Km 26 reached the highest values of permanent deformation, and, in addition, the specimen tested at optimum humidity + 2%, reached the maximum DP possible to be recorded by the LVDT of the equipment, in the second cycle of charging (5% SD). The soil at Km 824 deformed less, taking into account the last loading stage and both moisture and density conditions. Therefore, it is concluded that this technique for evaluating the behavior of the soil contributed greatly to the research, since, in a simplified way, it is possible to obtain more information on the mechanical performance of the soil.pt_BR
