RISQuantitative Estimation of Clay Mineralogy in Fine-Grained Soils
Publisher: American Society of Civil Engineers
Abstract: Stabilization design guidelines based on soil plasticity properties have certain limitations. Soils of similar plasticity properties can contain different dominant clay minerals, and hence, their engineering behavior can ...
Closure to “Quantitative Estimation of Clay Mineralogy in Fine-Grained Soils” by Bhaskar Chittoori and Anand J. Puppala
Publisher: American Society of Civil Engineers
Strength and Stiffness Characterization of Controlled Low-Strength Material Using Native High-Plasticity Clay
Publisher: American Society of Civil Engineers
Abstract: A research attempt was made to design a controlled low-strength material (CLSM) mix that can be used as bedding and haunch material for a pipeline by using the native soil as fine aggregate. Several CLSM mix designs were ...
Flowability and Density Characteristics of Controlled Low-Strength Material Using Native High-Plasticity Clay
Publisher: American Society of Civil Engineers
Abstract: In pipeline construction projects when high-plasticity clayey soils are encountered in the excavated trench material, they are typically landfilled and better quality materials are imported from outside quarry sources for ...
Evaluation of Swell Behavior of Expansive Clays from Internal Specific Surface and Pore Size Distribution
Publisher: American Society of Civil Engineers
Abstract: The interdependency of microsoil fabric-related properties and swell/shrink behavior of expansive soils needs to be identified to achieve a more thorough and accurate prediction of heave of expansive soils. In a recent ...
Evaluation of Swell Behavior of Expansive Clays from Internal Specific Surface and Pore Size Distribution
Publisher: American Society of Civil Engineers
Abstract: The interdependency of microsoil fabric-related properties and swell/shrink behavior of expansive soils needs to be identified to achieve a more thorough and accurate prediction of heave of expansive soils. In a recent ...
Addressing Clay Mineralogy Effects on Performance of Chemically Stabilized Expansive Soils Subjected to Seasonal Wetting and Drying
Publisher: American Society of Civil Engineers
Abstract: Premature failures in chemically stabilized expansive soils cost millions of dollars in maintenance and repair. One reason for these failures is the inability of existing stabilization design guidelines to take into account ...
Evaluating the Applicability of Biostimulated Calcium Carbonate Precipitation to Stabilize Clayey Soils
Publisher: ASCE
Abstract: Clayey soils with medium to high plasticity are prevalent in several parts of the world, causing billions of dollars in damage annually to various civil infrastructures. Several ground-improvement techniques can be employed ...
Polyurethane Grout Injection as Remedial Measure to Reduce Differential Heave in Pavement Sections Constructed over Expansive Soils
Publisher: ASCE
Abstract: Flexible pavement sections constructed over expansive soil deposits often undergo significant damage due to volume changes in the underlying soil strata. When expansive soil deposits are confined to shallow depths, ...
Experimental Studies on Stabilized Clays at Various Leaching Cycles
Publisher: American Society of Civil Engineers
Abstract: The effectiveness of chemical stabilization and its permanency were investigated by subjecting chemically treated soils to leaching tests by internal water flushing, which simulates moisture ingress/digress into subsoils ...
