Effects of Asphalt and Concrete Pavement Rehabilitation on Users and Businesses during Construction

Fisher, Mitchell II (2018-07-23)

Roadway maintenance and rehabilitation are critical tasks to sustain our transportation system. However, these activities often generate delays to road users, which can result in road user costs, work zone crash costs, and ...

The Effects of Blast Loading on the Interface of Concrete Masonry Units and Mortar

Doan, Kelsey (2019-04-18)

Masonry has always been a very efficient building material because of its low cost, availability, versatility, and construction simplicity. In terms of blast protection, masonry presents an enormous challenge: when ...

Effects of Intersection Features on Wrong-Way Driving

Wang, Jin (2018-03-22)

Wrong-way driving (WWD) crashes are much more likely to result in serious injuries or fatalities compared to all other crashes. The analysis performed in this dissertation shows, specifically, that the risk of a fatality ...

The Effects of Land Cover, Climate, and Urbanization on Groundwater Resources in Dauphin Island

Petty, Katherine (2011-11-21)

The effects of land cover change, climate change, and population growth on the groundwater resources of a barrier island were explored in this study. The relationship between land cover and groundwater recharge was studied ...

Effects of Oil Dispersants on the Transport of Oil Contaminants and Photolysis/Photocatalysis of Oil-Related PAHs

Cai, Zhengqing (2016-08-03)

Petroleum is the largest energy source consumed in the US today. Routine oil exploration, transportation, refining, and consumption process result in the release of a large amount of oil into marine environments. Oil spills ...

Effects of Polyacrylamide Hydrogel on the Properties of Sand

Graham, David (2010-08-18)

A study on the effects of polyacrylamide hydrogel on the properties of Ottawa sand was conducted. Laboratory testing included stress-controlled cyclic triaxial tests, consolidated undrained triaxial compression tests, and ...

The Effects of Sulfide on Pulp and Paper Wastewater Color Reversion

Esty, Jessica (2005-12-15)

More and more concern is being given to the aesthetics of wastewater, specifically the color of the resulting effluent. The underlying causes of colored wastewater suggest incomplete pollutant removal and unsuccessful ...

Engineered Treatment of As-Laden Regeneration Brine from Ion Exchange Processes

Steinwinder, Thomas (2006-05-15)

Arsenic (As) contamination of drinking water sources has been one of the most challenging global environmental issues. In the United States, the newly revised maximum contaminant level (MCL) of 10 µg/L requires thousands ...

Enhancement and Redevelopment of the Regional Lake Water Quality Model with Applications

Tasnim, Bushra (2020-08-17)

Water quality is a serious issue in most of the world in the 21st century. Many lakes are impaired with Harmful Algal Blooms (HABs). To provide better lake management and restoration, modeling of lakes is of utmost importance. ...

Erodibility Testing of Cohesive Soils

Mobley, Thomas (2009-07-13)

The Erosion Function Apparatus (EFA) is used to measure erosion rates for cohesive soil samples subjected to water velocities tangent to the sample surface. EFA testing was performed on soil samples taken from three bridge ...

Evaluating and Understanding of Bridge Scour Calculation

Pokharel, Sudan (2017-11-27)

Channel scour and channel instability at bridges are the major cause of bridge collapse caused by flooding. Currently, Departments of Transportation (DOTs) in the USA use the HEC-18 procedure and associated software, which ...

Evaluating Maintenance Techniques for Long-Term Vegetation Establishment on Disturbed Slopes in Alabama

Messer, Richard Clay (2011-06-28)

Sustainability of common bermudagrass on formerly disturbed slopes in Alabama has proven to be a difficult task in some cases. Failures of once successful stands of bermudagrass can be seen throughout Alabama on road ...

Evaluating Sediment Removal Efficiency of Catch Basin Inserts (CBIS) as a Post-Construction Water Quality Tool For Ohio Roadways

Basham, Dakota (2018-07-18)
