Resumo: | The loading application time by machinery tires and agricultural tires is one of the factors of soil compaction. We evaluated the effect of loading reduction time in uniaxial compression test, in laboratory, in some physical and mechanical parameters, approaching the loading field condition time by machinery with laboratory tests. Soil samples of two Oxisol and one Paleudult under different years of implementation of no tillage system (NT) and of different layers were collected and subjected to uniaxial compression tests, two times of loading application, 300 seconds per load, according to actual methodology and 30 seconds per load in the laboratory. We analyzed the soil deformation to each load, bulk density, pre-compression stress, recompress and compress indexes. Our results show that the reduction in the time of loading application can be introduced satisfactorily without changes at interested parameters. Furthermore, the soil deformation dynamic in the sample follow the elasto-plastic model used to determine the pre-compression stress, do not changing for the sigmoidal shape. |

The loading application time by machinery tires and agricultural tires is one of the factors of soil compaction. We evaluated the effect of loading reduction time in uniaxial compression test, in laboratory, in some physical and mechanical parameters, approaching the loading field condition time by machinery with laboratory tests. Soil samples of two Oxisol and one Paleudult under different years of implementation of no tillage system (NT) and of different layers were collected and subjected to uniaxial compression tests, two times of loading application, 300 seconds per load, according to actual methodology and 30 seconds per load in the laboratory. We analyzed the soil deformation to each load, bulk density, pre-compression stress, recompress and compress indexes. Our results show that the reduction in the time of loading application can be introduced satisfactorily without changes at interested parameters. Furthermore, the soil deformation dynamic in the sample follow the elasto-plastic model used to determine the pre-compression stress, do not changing for the sigmoidal shape. |
