An Experimental Study on Soil Water Characteristics and Hydraulic Conductivity of Compacted Soils
… that govern engineering behavior of unsaturated soils. In this study, a transient water release and imbibitions method (TRIM) is used to measure the SWCC and HCF under drying and wetting states, which accommodates integrated experimental and modeling techniques. The results of saturated hydraulic …

Resistência ao cisalhamento de solos compactados: uma proposta de tipificação
This paper with shear resistance of compacted soils, based on test performed to research borrow areas from a number of designed and/or constructed Brazilian dams. Stress-strain, pore-pression deformation, and efective stress path curves are analysed and as a result some typical soil behaviors were …

Um Estudo Físico-Químico-Matemático da Estabilização Alcalina de Solos Argilosos
… knowledge concerning reaction mechanisms of soils with alkaline chemical additives, and development of a mathematical model based on physical chemistry and application of chemical kinetics equations. Nucleation equations and Drosdov - Rotinyan equation seems to model satisfactorly the …

Effects Of The Soil Properties On The Maximum Dry Density Obtained Fro
… and other structures, the compaction of soils is needed to improve its strength. In 1933 Proctor developed a laboratory compaction test to determine the maximum dry density of compacted soils, which can be used for specifications of field compaction. The Compaction of soils is influenced …

Growth and Physiology of Several Urban Tree Species in Soils Disturbed by Construction Fill or Compaction
… cm of subsoil spread over the root zones), and compacted fill (same as fill soil, but compacted). Additionally, individual trees had tree wells (fill soil pulled away from trunks), or not. After three years, treatments had no consistent effect on tree growth, chlorophyll fluorescence, or soil …

Wetlands Area and Embankment Design for Stimulating Duck Nesting Habitat and Success in Sioux County, North Dakota
… Dakota. The embankment will be constructed from compacted soils taken from two locations that are within a half mile from the proposed embankment location to create a lower transport cost. The embankment will contain a weir that will be approximately 115 feet in length with five feet on each side …

Mitigation of harvesting disturbances on a forested wetland in the South Carolina lower coastal plain
… timber harvesting often results in rutted and/or compacted soils. These impacts damage inherent site and soil properties and can reduce subsequent pine seedling survival and growth. Site preparation treatments such as bedding, disking, and fertilization are often employed on harvested sites to …

Mechanical behaviour of compacted decomposed granite soil
… compression tests have been carried out on compacted samples and special attention has been given to the determination of the effects of the moisture condition on the behaviour. The test results show that the soil conforms to the basic features of critical state soil mechanics, although …

The role of living plant roots and cattle manure as a soil amendment in the alleviation of compacted coal mine soils
… soil which results in soil compaction. In mine soils, compaction is of great importance in plant growth and the environment because its high levels may adversely result in the degradation of soil structure, reduced nutrient distribution and reduced root growth, which eventually decreases plant …

Trees and Structural Soil as a Stormwater Management System in Urban Settings
… We examined whether tree roots can grow into compacted subsoils and if root penetration increases soil infiltration rate. Quercus velutina, Acer rubrum, and a no-tree variant were planted in 26.5 L (7 gal) containers and the rootballs surrounded by compacted clay loam. Roots grew into all …
