Mechanical Behavior Of Grouted Sands, Ryan C. Ortiz 2015 University of Kentucky

Mechanical Behavior Of Grouted Sands, Ryan C. Ortiz

Theses and Dissertations--Civil Engineering

Grouting techniques have been in used for many years, but several new grout materials have surfaced in recent decades that have re-defined the boundaries of the limitations of grouting programs. Typically these applications are used for seepage control in earthen impoundments, but strength of these earthen impoundments should be considered where there is potential for movement in the grouted soil mass. This study investigated initial conditions that could affect grout application effectiveness. The initial conditions in question were soil grain size and in situ moisture content. Two grouts were used, ultrafine and acrylate, and variations in pure grout properties were ...

Prediction Of Strength And Shear Modulus Of Compacted Clays Within An Unsaturated Critical State Framework, Corrie Walton-Macaulay

Theses and Dissertations--Civil Engineering

The objective of this research study is to determine whether the soil stiffness, from which the small-strain shear modulus is determined, can be used to predict the shearing resistance of compacted clay soil, which are invariably under conditions of partial saturation. The research program developed for this objective included three major soil testing programs of matric suction, shear modulus, and strength.

A method to estimate matric suction of field compacted clay soil was presented and it is based on the quantified effect of change in initial void ratio on the soil water characteristic behaviors. With the use of a non-nuclear ...

Miniature Cone Penetration Test On Loose Sand, Sepideh Damavandinejad Monfared

University of Western Ontario - Electronic Thesis and Dissertation Repository

Considering the difficulties associated with preparing loose sand samples in large calibration chambers and wide area of research on the behavior of loose sands, miniature calibration chamber experiments are used to perform cone penetration tests on soils in different states. A miniature cone calibration chamber has been designed and developed in this study. Nineteen tests have been performed on Ottawa sand and the results are compared to the available data in the literature. The accuracy of the results is validated by comparing the results with the suggested rate for the cone resistance in sands in literature. More specifically, results are ...


Modeling Pavement Distress Rates Within U.S. Air Force Airfields, Lauren Sahagun 2014 University of Nevada, Las Vegas

Modeling Pavement Distress Rates Within U.S. Air Force Airfields, Lauren Sahagun

UNLV Theses/Dissertations/Professional Papers/Capstones

Through the review of Pavement Condition Index (PCI) surveys completed at Air Force installations scattered across the continental United States, pavement engineers at the Air Force Civil Engineer Center propose that the predominant factor contributing to pavement distress development is climate. They suggest that within each pavement distress type (i.e. alligator cracking, rutting, spalling, etc.) a geographic pattern exists that is strongly correlated to the conventional climate zones within the US. Knowledge of these geographic patterns would equip pavement engineers and asset managers with a powerful tool to develop purposeful maintenance strategies specific to each distress type.

The following ...


Development And Use Of Moisture-Suction Relationships For Geosynthetic Clay Liners, Jacob Law Risken 2014 California Polytechnic State University - San Luis Obispo

Development And Use Of Moisture-Suction Relationships For Geosynthetic Clay Liners, Jacob Law Risken

Master's Theses and Project Reports

A laboratory test program was conducted to determine the moisture-suction relationships of geosynthetic clay liners (GCLs). Moisture-suction relationships were determined by combining suction data from pressure plate tests, contact filter paper tests, and relative humidity tests, then fitting water retention curves (WRCs) to the data. WRCs were determined for wetting processes and drying processes in terms of gravimetric moisture content and volumetric moisture content.

The effects of GCL type, hydration solution, wet-dry cycles, and temperature on the moisture-suction relationships were analyzed. The three GCLs of the test program consisted of configurations of woven and nonwoven geotextiles reinforced with needlepunched fibers ...

Civil, Construction and Environmental Engineering Conference Presentations and Proceedings

Maintaining operational safety and status of airport runways during snowfall events is a challenging issue that many airports are grappling with. Ice and snow impacts on transportation infrastructure systems add significant costs to the American economy in the form of snow removal, damaged pavement and lost productivity due to travel delays. Most transport category aircraft are prohibited from operating on runways covered by untreated ice or by more than ½ inch of snow or slush. Hence, it is imperative that both small and large airports maintain operational status during snowfall events to support the existing operations. Conventional ice and snow ...


Evaluation Of Volatile And Semi-Volatile Organic Compounds Potentially Associated With The Gas Shale Fracturing Process In The Fayetteville And Marcellus Shale, Karl Albert Oetjen 2014 Syracuse University

Evaluation Of Volatile And Semi-Volatile Organic Compounds Potentially Associated With The Gas Shale Fracturing Process In The Fayetteville And Marcellus Shale, Karl Albert Oetjen

Theses - ALL

With the recent growth of the natural gas industry coupled with technological advancements, gas shale fracturing has become an effective and highly profitable method for natural gas production. Unlike conventional natural gas extraction which may require vertical fracturing, gas shale fracturing relies on a method known as horizontal fracturing to remove gas trapped within the impermeable facies. Compared to vertical fracturing, horizontal fracturing requires larger amounts of fluids to be injected downhole under high pressure. These fracturing fluids can contain high concentrations of petroleum hydrocarbons with known adverse health effects. Due to the large volumes used, the potential for groundwater ...
