Estes fragmentos s?o denominados cascalho de perfura??o de petr?leo ou simplesmente res?duo de perfura??o de petr?leo. Nos locais de explora??o onshore s?o formados grandes dep?sitos de cascalho de perfura??o, material de onerosa destina??o final. Sendo assim, este trabalho apresenta uma pesquisa com o objetivo de avaliar o emprego de res?duo de perfura??o misturado a um solo later?tico, como material comp?sito a ser utilizado na execu??o de aterros compactados em obras de terra. Solo e res?duo foram avaliados atrav?s de difra??o de raios X (DRX), fluoresc?ncia de raios X (FRX) e mediante ensaios de laborat?rio tradicionalmente empregados na mec?nica dos solos, como, an?lise granulom?trica, determina??o de limite de liquidez e de plasticidade e ensaios de compacta??o. Ap?s a caracteriza??o de solo e res?duo individualmente foram estudadas misturas de solo e res?duo, segundo as dosagens de 2,5%, 5%, 10%, e 15% de res?duo em rela??o ? massa de solo seco. Essas misturas foram submetidas aos ensaios de compacta??o, CBR, cisalhamento direto e adensamento. Os resultados dos ensaios foram comparados com as normas vigentes do DNIT para execu??o de aterros compactados. Os resultados encontrados nos ensaios das misturas atendem aos par?metros m?nimos necess?rios, permitindo, sob o ponto de vista da an?lise geot?cnica, a utiliza??o dessas misturas para execu??o de aterros compactados / The drilling of wells for petroleum extraction generates rocks and soils fragments, among other residues. These fragments are denominated petroleum drilling gravel or simply petroleum drilling residue. On the sites of onshore exploration are formed big deposits of drilling gravel, an expensive final destination material. This work aims at evaluating the addition of drilling residue to a lateritic soil, as composite material, for construction of compacted fills for earth work projects. Soil and residue were evaluated by X-ray diffraction (XRD) and X-ray fluorescence (XRF) and by laboratory tests traditionally used in soil mechanics, as particle-size analysis of soils, determination of liquid and plasticity indexes and compaction test. After soil and residue characterization, soil-residue mixtures were studied, using dosages of 2,5%, 5%, 10%, and 15% of residue in relation to the dry soil mass. These mixtures were submitted to compaction test, CBR, direct shear test and consolidation test. The test results were compared to the current legislation of DNIT for compacted fill construction. The results showed that the mixtures presented the minimal necessary parameters, allowing, from the point of view of geotechnical analysis, the use of these mixtures for construction of compacted fills
