Previous issue date: 2014-11-17 / A perfura??o de po?os para extra??o de petr?leo gera, entre outros res?duos,
fragmentos de rochas e solos. 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
