Book Description
In deep stabilization of soft soils in Sweden, dry binders such as cement and quicklime are normally used. Mixing dry binders into the soils will lead to a lower degree of saturation than that of the unstabilized soils, which normally are fully saturated before stabilization. In triaxial testing of stabilized soils, the applied back pressure chosen for the tests may affect the degree of saturation and in turn also the results obtained. A number of triaxial tests have been performed using different back pressures in order to study the effect on measured shear strengths of stabilized organic soils and clays. The effect of rate of strain on the strength of stabilized organic soils was also studied in a series of tests. The results show that in particular the chosen back pressure can greatly affect the strength of stabilize soils, although the rate of strain can also exert an influence on the measured strength.

Book Description
A relatively inexpensive system has been developed for applying repeated axial loading to test specimens in the existing triaxial equipment used for studying the strength behavior of stabilized and/or compacted soils at confining pressures up to 1000 psi. Two independent systems were constructed and each system can subject three triaxial test specimens to about the same cyclic loading. The equipment has been operational for about one year, during which time it has proven to be simple and reliable to operate. Instrumentation for monitoring and recording loads, deformations, and pressures during repeated loading has also proved to be satisfactory with the exception of the load cells located inside the triaxial cell chambers. Preliminary test results using this equipment on a cement-stabilized silt show that repeated loading does not have a detrimental effect on the frictional resistance of this soil at ultimate but can partially destroy the cohesive resistance at the Mohr-Coulomb failure condition.

Book Description
Verdigre located in North Eastern Nebraska experienced slope failures that occurred in the rural areas south and southeast of the city. The geological formations of theses slopes largely consist of several layers of weathered shales and glacial tills. Weathered shales consist mainly of clay minerals while glacial tills are a mixture of clays, silts, and sands. It is believed that the weathering process reduced the shear strength of the soils leading to slope failures. In this study, strength characteristics of Xanthan gum and Gellan gum treated soil specimens compacted at the optimum moisture content for field application were investigated so that the biopolymer treated soils may be properly used to stabilize the slopes. The untreated and treated samples were subjected to a wet-freeze(-6oF)- thaw(167oF)-dry weathering process up to 8 cycles, then sheared by the direct shear device to investigate the effects of weathering on the strength characteristics of compacted soils samples. Some of the important findings are as follows. • Increasing Xanthan gum and Gellan gum concentrations increased the shear strength of the glacial tills and weathered shales. Xanthan gum was more effective than Gellan gum in both soils. • For untreated and treated glacial tills and weathered shales, the shear strength of the soils decreased as the number of the weathering cycles increased. However, the shear strength reduction from 4 cycles to 8 cycles was insignificant. • The shear strength of the treated glacial tills and weathered shales mixed with 1.5% of Xanthan gum at 8 weathering cycles was 88% and 83% of the untreated unweathered ones, respectively. That might indicate the sustained long-term stability achieved by stabilizing the soils using Xanthan gum. • The effect of using a biopolymer content higher than 1.5% on the shear strength of the glacial tills and weathered shales was not apparent at higher weathering cycles • Xanthan gum and Gellan gum were more effective in glacial tills than in weathered shales.
