Assessing Impact of Climate Change on Oklahoma Bridge Deck and Superstructure Deterioration using National Bridge Inventory Data
(2017-05-13)
Bridge deterioration is a prominent problem in the United States. Bridge deck and superstructure elements are often exposed to harsh conditions and their performance is critical in the overall sufficiency of a bridge. Many ...
Determining the Feasibility of Best Available Treatment Versus Line Extension for Radionuclide Contamination in the Kickapoo Tribe of Oklahoma Jurisdiction Area
(2019-05-10)
This project aims to compare best available treatment (BAT) options to a line extension, therefore, presenting residents within the Kickapoo Tribe of Oklahoma (KTO) jurisdictional area with the most effective, in terms of ...
Development Length of 0.6 in. Prestressing Strands in Precast, Prestressed Calcium Sulfoaluminate Cement Concrete
(2016-12-16)
Calcium sulfoaluminate cement is a very rapid setting, hydraulic cement that releases
approximately half as much carbon dioxide during production as conventional portland
cement. Calcium sulfoaluminate cement produces ...
QUANTIFYING HYDRAULIC CONDUCTIVITY IN MINE DRAINAGE PASSIVE TREATMENT SYSTEM VERTICAL FLOW BIOREACTORS
(2016-12)
Heavy industrial mining has occurred in the United States for more than 100 years, and in many cases, has led to large-scale environmental degradation, especially from historical operations where mining occurred prior to ...
EVALUATION OF STORMWATER TREATMENT BY VARIOUS REACTIVE MEDIA FOR BIORETENTION CELL DESIGN CONSIDERATIONS
(2018-05)
Bioretention cells (BRC) can be effective at filtering particulate pollutants from stormwater runoff, but substantial removal of the dissolved pollutant fraction is challenging. Various reactive treatment media for BRCs ...
Development and implementation of a wetlands volunteer monitoring pilot program for Oklahoma
(2000)
Due to limited public and private manpower,citizens have become valuable tools for collecting environmental data. Currently over 700 volunteer environmental monitoring programs in the United States are actively collecting ...
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 ...
Ultra-High Performance Concrete for Connections of Precast, Prestressed Girders Made Continuous for Live Load
(2019-08-01)
Continuity joints have often been employed in bridges with precast, prestressed girders to increase the overall ability of bridges to distribute live loads by making two simple spans continuous. However, if the continuity ...
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 ...
