Stabilization of Marginal Soils Using Recycled Materials

Abstract: Loose sand, soft clays, and organic deposits are often unsuitable for use in construction due to their less-than-desirable engineering properties Traditional methods of stabilizing these soils through in-situ ground improvement or replacement techniques are costly Recycled materials such as scrap tires, plastics, ash, slag, and construction debris provide a viable alternative both for their relatively lower cost and desirable engineering properties Furthermore, use of recycled materials prevents their disposal into landfills, which are approaching capacity in Florida and across the nation This report provides a comprehensive assessment of various recycled materials that can be used to stabilize marginal soils in Florida Particular attention is given to material availability and environmental properties in addition to engineering properties A methodology is proposed to guide Florida Department of Transportation (FDOT) personnel in evaluating, testing, and approving any new material for use as a highway construction material

Lime stabilization of organic soils

Abstract: The potentials of improving the engineering characteristics of organic soils found in Louisiana were studied. Laboratory studies of approximately 1,100 samples of inorganic and organic soils showed that plasticity and strength are improved by the addition of lime. Changes in pH of soil-lime mixtures showed that increased levels of lime treatment were able to neutralize the acidity of organic matter in the soil and initiate the soil-lime reaction.

Effect of the Ratio between Porosity and SiO2 and Al2O3 on Tensile Strength of Zeolite-Cemented Sands

Abstract: The practice of soil treatment using cement and zeolite is an approach that can be widely used in soil stabilization particularly in road construction, as a support layer for shallow founda...

Sydney Soil Model. I: Theoretical Formulation

Abstract: In this paper a theoretical study of the behavior of structured soils, including both clays and sands, is presented. A new model, which is referred to as the “Sydney soil model,” is formulated within the framework of critical state soil mechanics. In the proposed model, the mechanical behavior of soil is divided into two parts, that at a reference state and that attributed to the influence of soil structure. The reference state behavior is formulated according to the soil properties at the critical state of deformation, based on the concept of plastic volumetric hardening. The effects of structure are captured in the model by incorporation of the additional voids ratio that arises owing to the presence of soil structure. The formulation is generalized to include both isotropic compression and general shearing. In part I of this paper, a new theoretical framework for modeling structured soil behavior and the formulation of the proposed Sydney soil model are introduced. In part II of this paper, the Sydney ...
