Behavior of Geosynthetic-Encased Stone Columns in Soft Clay: Numerical and Analytical Evaluations

October 24, 2018
The type of improvement technique that will be applied to a soil beneath an embankment depends on the nature of the problematic soil existing at the site. Soft soils beneath embankments typically present high compressibilities and low shear strengths. In some cases, geosynthetic-encased stone columns (GECs) have shown advantages over other solutions to improve e...

On the Compatibility and Theoretical Equations for Mixtures of Tropical Soils and Bentonite for Barrier Purposes

November 09, 2018
Vast regions of the globe are covered by tropical soils, increasing the perspective of using them for barrier design at solid/liquid disposal facilities. They comprise diverse pedological taxonomies, but have common features, specially the dominant mineral composition of quartz, kaolinite clay and Fe-Al-Mn oxides/hydroxides. Despite the vast occurrence, sometime...

The Performance of a Sand Reinforced with Coconut Fibers Through Plate Load Tests on a True Scale Physical Model

September 18, 2018
The use of recycled materials has experienced a growing global interest in the last decades. Products like natural fibers are being studied to replace synthetic fibers in some applications because they are renewable resources that have a lower cost. Fibers can be used as reinforcement for covers of landfill sites, landfilling over soft soils, and evapotranspirat...

Porosity Changes of Compacted Soil Percolated with Acidic Leachate

October 02, 2018

This paper evaluates porosity changes in compacted soil subjected to acidic leachate percolation through different dry unit weights. The porosity of compacted soil is presented in different nominal porosities or dry unit weights (41.9% and 15.5 kN/m3, 43.8% and 15.0 kN/m³, and 45.7% and 14.5 kN/m³) percolated with a sulfuric acid solut...
