Development of precast, prestressed concrete pavement technology
(2013-12)
Precast prestressed concrete pavement (PPCP) can provide many advantages over other pavement alternatives whether asphalt or concrete. The possible advantages are thinner pavement, faster construction, increased durability, ...
Characterization of pollutant emissions and fuel use for CNG transit buses
(2015-05)
Transit agencies have historically relied on diesel buses to move their passengers; however, many agencies have adopted alternative fuels such as compressed natural gas (CNG). New knowledge is needed to accurately assess ...
Investigations of a Precast Bridge Deck SystemInvestigations of a precast bridge deck system

Scope and Method of Study:
Study examining MDC units couple treating carbohydrate base stream waste and artificial seawater
(2014-05)
Investing the biomass energy production in microbial desalination cells (MDCs) to drive another process like desalination has gained a great attention these days pushing researchers to try to unveil the limiting factors ...
Strategies for compliance with stage 2 Disinfectants and Disinfection Byproducts Rule for surface water treatment facilities in northeastern Oklahoma
(2012-07)
Scope and Method of Study: The Environmental Protection Agency (EPA) recently created new regulations that better protect human health but that also make achieving compliance more difficult for existing water treatment ...
Direct observations on microstructure evolution of cement systems at early ages
(2017-05)
There is limited understanding of the mechanisms or direct measurements of cement paste hydration, as the main component that determines mechanical, durability, and rheology properties of concrete. This dissertation uses ...
Visualization and intelligent solutions for big pavement data
(2018-07)
Pavement visualization and crack detection are two important components supporting modern pavement condition survey. In this dissertation, two major goals are accomplished based on implementable algorithms. 1) The long-distance ...
Aggregate proportioning for slip formed pavements and flowable concrete
(2015-07)
This is an investigation into developing a relationship between aggregate proportioning and the workability of concrete for slip formed pavements and flowable concrete applications. Workability tests were developed for ...
Determining suction compression index of expansive soils based on non-linear suction-volumetric strain relationship
(2016-12)
Expansive soils have always been problematic in many parts of the United States and the world. This is due to the stresses they exert on buildings' foundations, pavements, and other geotechnical structures. In the United ...
Soil matric suction and active zone depth in Oklahoma
(2017-05)
Soil matric suction is an important parameter in unsaturated soils. The shrink-swell properties of expansive soils is controlled by soil matric suction. Matric suction variations cause volume change in expansive soils, ...
