If end criteria for permeability tests of Peirce and Witter and Bowders et al. P3 was submitted to gradients of 5, 10 and 15, with respective -6 -6 -7 end-of-test hydraulic conductivities of 8. This effect was not evident in this investigation. The aim was to analyse the advantage of re-compaction of local soil in small landfills where there is no requirement for bottom layers. RePEc uses bibliographic data supplied by the respective publishers. Pedologically, the upper soil layer is classified as a red latosol IBGE Measured hydraulic conductivity varies with the applied hydraulic gradient and, more significantly, with test duration.

Standard D Standard test methods for liquid limit, plastic limit, and plasticity index of soils. Geotechnical characterization of the local soil is presented in Table 1.
Permeability tests with undisturbed specimens: A summary of the physical indexes of the specimens and test conditions is presented in Table 2. Low-cost pavements with lateritic soils.
The stratigraphy at the site comprises sandstones intercalated with effusive basaltic igneous rocks, and sediments related to drainage networks. The referenced dam presents homogeneous section composed of clay soil, a height of 70 meters, a width of 12 meters, and upstream slope with inclination 1V: In this study, hydraulic -9 -6 conductivity to water varied from 8.

The investigated soil is the most granular variety of latosols in the Southeast and Central regions nbrr the country, thus suggesting that better hbr are to be expected of compaction of local lateritic soils in other sites. Due to the complexity generated by the combination of loads and the difficulty in determining the parameters, analyses of rapid drawdown are usually performed considering the immediate reduction of water level upstream.
