Abstract in Portuguese
Apresenta-se um estudo comparativo entre os resultados do ensaio de compactação realizado segundo as normas brasileira e americana, que diferem entre si na energia de compactação. Para isso foram usados três solos , dois arenosos, um com de 12% de argila e outro com 34% de argila, e um argiloso com 20% de areia. Os ensaios foram realizados sem reuso do solo, com um intervalo em torno de 3% da umidade ótima e um procedimento que permitisse acrescentar quantos pontos fossem necessários para o traçado da curva. Os resultados obtidos mostraram que para o teor de umidade ótimo não há diferença sensível mas para a massa específica seca máxima, as diferenças são sensíveis, principalmente para os solos arenosos.

Abstract in English
There are between brazilian (ABNT: J\tffi-33) and american (ASTM: D-698) standards, both about soil compaction, some differences in the compaction energy. To verify if these differences modify the results of the tests were perfomed laboratory compaction tests with three different soils: two sandy, one with less 12% of clay and other with 34% of clay, and one clayey with 20% of sand. The tests were perfomed with moisture content varying within the interval ± 3% of optimun and do not reusing the soil; other cares were taking during the tests. The results of each test are showed and there are sensitive differences between the standards, principally for the sandy soiL
