1. Study of soils used with subgrade and sub-ballast in Brazilian railways
Abstract Brazil has an extremely limited railroad network compared to other developed and developing countries. There are projects to expand this mesh. Knowing that the cost of implementing a railroad is high, research for solutions that allow cost reduction is of great importance. But the parameters of the materials used in the subgrade and sub-ballast laye

2. Efeito da adição de resíduos da construção e demolição (RCD) nas propriedades hidromecânicas de um solo areno-argiloso
RESUMO Diante de uma produção cada vez mais evidente dos resíduos sólidos resultantes das ações humanas, tais como os Resíduos da Construção e Demolição (RCD), destinar adequadamente estes materiais tem ganho importância no cenário atual, pois quando dispostos irregularmente atuam de forma degradante sobre o meio ambiente e contribuem com a prol

3. Field compaction control by way of correlation between elasticity module and layer rigidity with moisture content
Abstract The present research had as its basic objective to contribute with the improvement in the quality control evaluation of the compacting process in road works. The real contribution of the survey is to establish an innovative way of controlling the compaction process in the field, with employment of the Humidity versus Rigidity and the Humidity versus

4. Soybean Tillage Systems and Physical Changes in Surface Layers of Two Albaqualf Soils
ABSTRACT A compacted subsurface soil layer can be a limiting factor for soybean growing, reducing soybean yield. The aim of this study was to evaluate the effect of different tillage systems on the physical properties of two Albaqualf soils of the Central Plains region in the state of Rio Grande do Sul in southern Brazil. Two experiments were conducted: one

5. Root Distribution of Peach Rootstocks Affected by Soil Compaction and Acidity
ABSTRACT Root growth can be limited by physical and chemical conditions of the soil. Compacted and acidic soils, where there is an occurrence of exchangeable Al, constitute barriers to use of the soil by plant roots. The hypothesis of this study was that physical and chemical properties of the inter-row soil of a peach orchard influence the root distribution

6. Utilização de mistura de solo saprolítico com bentonita na construção de revestimento de fundo de aterros sanitários. / Use of saprolite soil mixture with bentonite in the construction of landfill liner.
No Estado de São Paulo, a CETESB (1993), a exemplo da maioria das legislações e regulamentações ambientais em todo o mundo, recomenda que o coeficiente de permeabilidade da camada de impermeabilização de fundo de solo compactado (CCL ou compacted clay liner) em aterros sanitários seja menor ou igual a 10\ POT.-9\ m/s. O material mais utilizado para e

8. Influência de variáveis de compactação na estrutura dos solos: caracterizações geotécnica, química, mineralógica e microestrutural / Influence of laboratory compaction variables in soils structure: geotechnical, chemical, mineralogical and microstructural characterizations
This research addressed the effect of laboratory methods of static and dynamic compaction on compaction parameters, mechanical strength and compressibility of three gneiss residual soils (two young and one mature soils) and two granite residual soils (one young and one mature soils) from the Minas Gerais State, Brazil. Disturbed soils samples were collected,

9. Resistência de um solo não saturado a partir de ensaios com teor de umidade constante (CW) / Shear strength of an unsaturated soil from constant water content tests
In many parts of the world, geotechnical engineers frequently deal with unsaturated soils, and the performance of constructions on such soils depends on their mechanical characteristics, and among them, the shear strength. The unsaturated soil shear strength can be experimentally determined by using techniques which allow soil suction control or measurement

10. tropical soils, bentonite, hydraulic conductivity, compatibility, barriers. / CONDUTIVIDADE HIDRÁULICA E COMPATIBILIDADE EM COMBINAÇÕES DE SOLO TROPICAL E BENTONITA PARA USO EM BARREIRAS
Barriers are key elements for the environmental protection in waste disposal sites. Additionally, compacted tropical soils have great potential to be used in these barriers, once some technical matters are correctly addressed, including low hydraulic conductivity and adequate compatibility to the disposed fluids. In this context, the bentonite addition in tr

11. Shear strength of an unsaturated soil with direct measurement of suction / Resistência ao cisalhamento de um solo não saturado com medida direta de sucção
The purpose this study was to measure the suction with high capacity tensiometer (HCT), placed at the bottom of the sample, during shear strength tests on a compacted soil. Three kinds of shear strength tests were performed on the sample in different conditions of saturation: triaxial consolidated drained in saturated condition, triaxial consolidated undrain

12. Estudo comparativo dos ensaios de CBR e Mini-CBR para solos de UberlÃndia-MG / Comparative study of tests of CBR and Mini-CBR for soils of UberlÃndia - MG
This present work shows a comparative study between the tests of CBR and the tests of Mini-CBR to the soils of UberlÃndia - MG, aiming at to extend the use of the Mini-CBR, in view of its advantages in relation to the CBR. The main advantages of the test of Mini-CBR are more practical, demands a smaller amount of samples, it has a faster execution procedure
