Validation of Portable Handheld X-Ray Fluorescence (PHXRF) on Stabilized Subgrade Projects for Construction Quality Control and Geotechnical Forensic Investigations
(2016-05-13)
Problematic subgrade soils are often strengthened through pozzolanic reactions and/or cementing using various types of chemical stabilizers, such as lime, cement kiln dust, and fly ash. The amount of stabilizer needed for ...
PERFORMANCE MONITORING AND ANALYSIS OF GEOSYNTHETIC REINFORCED SOIL INTEGRATED BRIDGE SYSTEMS (GRS-IBS) IN OKLAHOMA
(2017-05-12)
In 2013, the University of Oklahoma, together with the Oklahoma Department of Transportation (ODOT) and the Oklahoma Bureau of Indian Affairs (BIA), started a feasibility study of GRS-IBS, which had been promoted by the ...
Evaluation of Surface Preparation and Bond Angle Combinations for Joint Replacement using Ultra-High Performance Concrete
(2018-05-12)
Deterioration of bridges is often attributed to declining performance of the longitudinal connections between precast members or transverse deck joints. Ultra-high performance concrete (UHPC) is a cementitious composite ...
INFLUENCE OF RETARDERS ON SHRINKAGE AND COMPRESSIVE STRENGTH IN RAPID SET CONCRETE
(2018-05-12)
The purpose of this project is to study the influence and behavior of citric acid on calcium sulfoaluminate (CSA) concrete and compare with industry standard retarders. A review of the available literature on calcium ...
Comparative Hydraulic and Cost Analyses of Single and Dual Water Distribution Systems Using Nonpotable Water for Urban Irrigation in Norman, Oklahoma
(2017-12)
Drought has caused water resource shortages throughout Western and Midwestern United States for many years, particularly in California, Nevada, Arizona, Texas, and Oklahoma. This has led many communities to evaluate alternate ...
TOTAL WATER LEVEL MODELING IN THE NORTH CAROLINA COASTAL PLAIN: COMPARING ADCIRC AND HEC-RAS
(2017-12-15)
The purpose of this Master’s thesis was to develop and compare an ADCIRC and ADCIRC/HEC-RAS paired model for the purpose of total water level forecasting using the Tar River and Pamlico Sound area as a test case. ADCIRC ...
Feasibility Study of Geosynthetic Reinforced Soil Integrated Bridge Systems (GRS-IBS) in Oklahoma
(2016-05)
Bridges supported on deep foundations constitute the conventional and standard construction practice. While deep foundations provide several advantages for bridges with respect to their stability and performance, they also ...
Implementing Fiber-Reinforced, Self-Consolidating Concrete as a Repair Material for AASHTO Prestressed Concrete Girders
(2018-08)
In 2017, the American Society of Civil Engineers released a report card stating that, of the 614,387 bridges in the United States, nearly 40% are past their design life. Within a few months of the report, the U.S. Department ...
UNDERSTANDING THE SEISMIC RESPONSE OF SINGLE HELICAL PILES IN DRY SANDS USING A LARGE-SCALE SHAKE TABLE TEST
(2017-05)
Helical piles are deep foundations composed by a steel shaft and single or multiple helical plates welded at their tip or throughout their lead section, respectively, which allows them to be screwed into the ground during ...
Evaluation of Catchment-Scale Stormwater Runoff Management on First-Flush Water Quality and Storm Discharge Quantity
(2018-12)
Urbanization and resulting imperviousness has caused increased pollutant loadings into receiving water bodies. One of the main sources of pollutant loads is stormwater runoff. The purpose of this study was to investigate ...
