Identifying latent diversity, equity, inclusion, and accessibility (DEIA) indicators for multimodal transportation systems
(2023-12-15)
Traditional transportation policies unfairly affect marginalized travelers and under-represented groups, limiting their access to social and economic opportunities and contributing to residential segregation. Even though ...
Assessing the potential for beneficial reuse of passively-treated mine waters for livestock watering and crop irrigation
(2020-12-18)
Passive treatment of mine drainage provides demonstrated water quality improvements and substantial removal of ecotoxic metals via biogeochemical, microbiological, and physical mechanisms. When mine drainage is treated to ...
Effects of Hydraulic Design and Retention Time on Removal of Constituents of Emerging Concern from Secondarily Treated Wastewater Effluent in Treatment Wetland Mesocosms
(2023-12-15)
Treatment wetlands (TWs) are an ecologically engineered, natural infrastructure approach designed specifically for water quality improvement via natural biogeochemical, physiochemical, and microbiological processes. The ...
Comparative study of proprietary and non-proprietary ultra-high performance concrete as partial-depth joint replacement
(2020)
Ultra-High Performance Concrete (UHPC) is a special type of concrete that has unique properties that are desirable for various types of construction projects. The most common form of UHPC used in the field is a proprietary ...
Evaluation of Functionality and Service Life of Ultra-High Performance Concrete Link Slab Connections for Bridges
(2022-05-14)
Structural longevity and sustainability are rising priorities in bridge construction. Accelerated bridge construction is a response to such a demand, with a goal of providing bridges with a longer service life in a ...
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 ...
Tensile Behavior of Ultra-High Performance Concrete Under Direct Tension
(2020-07-30)
Ultra-High Performance Concrete (UHPC) is a product that has improved mechanistic properties as compared to traditional concrete and is defined by the Federal Highway Administrations (FHWA) as having a post-cracking tensile ...
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 ...
Beam Shear in Mild Reinforced Ultra-high-performance Concrete
(2022-08)
Ultra-high-performance concrete (UHPC) is being utilized in bridge construction primarily for deck overlays and end-of-girder and beam repairs of deteriorated traditional concrete elements. UHPC has been used selectively ...
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 ...
