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 ...
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 ...
The Effect of Pore Water Evaporation on Transport of Caffeine, Propranolol, and Ciprofloxacin: A Sand Column Study and Model Simulation
(2016-12)
The purpose of this study was to explore the transport of selected pharmaceuticals under saturated and unsaturated conditions, simulating environmental processes of evaporation and flooding. Caffeine (a stimulant), ...
Assessment of Partial Joint Penetration Welds on Bolted End-plate Connections for use in Intermediate Moment Frames
(2016-05-13)
End-plate moment connections are a very common connection type used in the metal building industry today. Bolted end-plate connections are found where a rafter is joined to a column and consist of a steel plate welded to ...
The effects of temperature on compressive strength of rapid setting concrete
(2011)
Rapid setting concrete using Calcium Sulfoaluminate (CSA) cement has been around since the 1960's to meet the need for construction projects with limited time frames. These projects range from quick foundation work to rapid ...
The Use of Recycled Material Backfills to Mitigate the Effects of Expansive Soils on Subterranean Structures
(2016)
The extreme annual weather patterns of the Midwest United States have created a demand for basements as emergency shelters in both residential and commercial structures. However, with the majority of the Midwest experiencing ...
Modeling and Evaluation of Constituents of Emerging Concern Through Wastewater Treatment Processes
(2016-05-13)
Constituents of emerging concern (CECs) have accumulated in drinking water source supply over the past decades. Although there are currently no established treatment standards, CECs should be of concern to the public and ...
Evaluating Low Impact Development Best Management Practices as an Alternative to Traditional Urban Stormwater Management
(2016-08-12)
The Trailwoods residential neighborhood (Norman, OK) included two instrumented watersheds (each approximately 2.3 acres), with the purpose of quantifying the impact on stormwater quantity and quality through implementation ...
Performance of Fiber-Reinforced Self-Consolidating Concrete for Repair of Bridge Sub-Structures
(2016-05)
The damage of various reinforced concrete elements accounts for significant annual expenditures by state and federal transportation agencies on bridge maintenance, repair, or replacement. With the rising costs of materials ...
