Addressing the Geotechnical Challenges Posed by Soft Clays
Publisher: American Society of Civil Engineers
Energy-Based Approach to Assess the Performance of a Granular Matrix Consisting of Recycled Rubber, Steel-Furnace Slag, and Coal Wash
Publisher: ASCE
Abstract: Ballasted track progressively deteriorates due to ballast degradation and track deformation under dynamic loading, and this process accelerates when train speeds increase and axle loads become heavier as the railways are ...
Analysis of Deformation and Degradation of Fouled Ballast: Experimental Testing and DEM Modeling
Publisher: ASCE
Abstract: The deformation and degradation of fouled ballast have been examined by large-scale triaxial tests and discrete element modeling (DEM) to understand how clay fouling changes the shear strength and micromechanical aspects ...
A Coupled CFD–DEM Approach to Examine the Hydraulic Critical State of Soil under Increasing Hydraulic Gradient
Publisher: ASCE
Abstract: Increasing hydraulic gradients and associated seepage in a soil foundation accompanied by a reduction in effective stress, degradation of soil stiffness, and diminished internal stability contribute to adverse conditions ...
Role of Rubber Crumbs on the Stress-Strain Response of a Coal Wash Matrix
Publisher: ASCE
Abstract: The recycling of waste materials (e.g., coal wash, steel slag, recycled rubber, and fly ash) is becoming increasingly popular in ground engineering projects. While the physical properties of these waste materials can ...
Stress-Strain Degradation Response of Railway Ballast Stabilized with Geosynthetics
Publisher: American Society of Civil Engineers
Abstract: Large cyclic loading on ballasted railroad tracks is now inevitable owing to an increased demand for freight and public transport. This leads to a progressive deterioration and densification of railroad ballast and ...
Deformation Behavior of Lignosulfonate-Treated Sandy Silt under Cyclic Loading
Publisher: American Society of Civil Engineers
Abstract: Although many traditional soil stabilizers (e.g., lime, cement, gypsum, and fly ash) have been widely and effectively used for ground improvement, they often adversely affect the surrounding soil and groundwater environment. ...
Internal Stability of Granular Filters under Static and Cyclic Loading
Publisher: American Society of Civil Engineers
Improved Performance of Ballasted Rail Track Using Geosynthetics and Rubber Shockmat
