Development of Specifications for ALDOT Mass Concrete Construction
(2016-12-09)
In mass concrete construction, concrete temperature requirements must be established to
prevent delayed ettringite formation (DEF) and thermal cracking. This involves limiting the
maximum allowable concrete temperature ...
Identifying Potential Cisco Refuge Lakes in Minnesota under Future Climate Warming Scenarios
(2016-12-09)
Fish habitat models were developed and applied to investigate the impacts of future climate change on cisco oxythermal habitat in Minnesota lakes. Cisco Coregonus artedi is the most common cold-water stenothermal fish ...
Effects of Oil Dispersants on the Transport of Oil Contaminants and Photolysis/Photocatalysis of Oil-Related PAHs
(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 ...
Full Scale Testing of Two Excavations in an Unsaturated Piedmont Residual Soil
(2016-01-06)
Residual soil behavior can be difficult to predict using current geotechnical formulas, because it exhibits properties that are not common to transported soils. These unique properties are mainly influenced by the fabric ...
Improving Camber Predictions for Precast, Prestressed Concrete Bridge Girders
(2016-05-03)
In precast, prestressed concrete construction, the eccentricity of the prestressing force typically results in a net upward girder deflection known as camber. Camber is first observed at the time of prestress transfer and ...
Development of composite beam theory and its application in composite and prestressed concrete structures
(2016-05-13)
For some complex structural engineering problems like behavior of sandwich structures and prestressed concrete structures, extensive experimental works and finite element analyses might not be able to help understand the ...
Measuring and modeling stormwater runoff from an interstate in a rural/forested watershed
(2016-12-12)
In hydrological research, roadways are often defined simply as an increased impervious portion of a watershed or a flow blocking structure. The research presented in this dissertation examines the effects of highway crossings ...
Behavioral, Operational and Safety Effects of Red-Light Cameras at Signalized Intersections in Alabama
(2016-11-03)
Statistics reveal that from 2007-2011 an average of 751 people died each year in red-light running (RLR) crashes in the U.S. Past studies showed that red light cameras (RLCs), as an enforcement countermeasure, can lower ...
Evaluating the Contribution of Asphalt Binder from Recycled Asphalt Shingles in Asphalt Concrete
(2016-05-04)
The use of Recycled Asphalt Shingles (RAS) to replace a portion of the virgin asphalt binder in asphalt mixtures has been increasing over the past several years due to environmental and economic motivations. Yet, since ...
3-D Model Development of Metal Building Systems with Hard Walls
(2016-04-05)
Metal Buildings with precast concrete or masonry walls (hard walls) have been identified by analytical modeling, shake table tests, and earthquake reconnaissance as being susceptible to collapse. While the steel frames ...
