Resumo: | Abstract The present article presents the study of three laterites from the Triãngulo Mineiro and Alto Paranaíba region, aiming to use it as a pavement base. The methodology used consisted of carrying out the tests prescribed by the DNIT 098/2007 standard and, as a complementary methodology, linear contraction, MCT classification, modulus of resilience and X-ray diffractometry were introduced. Four mixtures of laterite with sand were prepared aiming to correct the plasticity of the materials. Three samples of laterites and three of the four mixtures with sand showed sand equivalent values lower than 30%, showing that this is a characteristic of laterites in the region. Only the mixture LatJ3+A4 (70x30) presented a sand equivalent greater than 30%, but this sample presented the worst plasticity indicators in relation to the other mixtures. These results showed the need for further studies on the use of the sand equivalent of laterites. The linear contraction associated with the liquidity limit proved to be more accurate and efficient for the control of plasticity characteristics than the plasticity index together with the liquidity limit and the sand equivalent. |
