Quality Control, Sensitivity Analysis, and Development of Traffic Factors for Mechanistic-Empirical Pavement Design
(2013-11-15)
The Mechanistic-Empirical Pavement Design Guide (MEPDG) is well-recognized as the next generation of pavement design. State transportation agencies across the U.S. are moving toward this method by implementing the MEPDG ...
The Influence of Colloidal Kaolinite on Th(IV) Transport in Saturated Porous Media
(2013-11-11)
Many laboratory and field studies have indicated that colloid mobilization was the most important potential source of enhancing the transport of a variety of contaminants in groundwater. However, limited research studied ...
Using GPS and Accelerometers to Identify Preferred Locations for Physical Activity Participation and Commuter Mode Choice
(2013-11-08)
As cities seek to foster more livable and active communities, much attention is being placed on promoting physical activity through active transport and wellness activities. As such, it is important that city planners and ...
Live-Load Response of In-Service Bridge Constructed with Precast, Prestressed Self- Consolidating Concrete Girders
(2013-11-08)
In order to assess the viability of a bridge constructed with precast, prestressed, self-consolidating concrete (SCC) bridge girders in the state of Alabama, the Alabama Department of Transportation (ALDOT) sponsored an ...
Understanding and Estimating Travel Times of Overland Flows on Planes
(2014-04-23)
Estimating travel time of overland flow is one of the important studies in hydrology. A quasi-two-dimensional overland flow model (OFM) with the options of dynamic, diffusion, and kinematic wave approximation integrated ...
Proposed Improvements to Overlay Test for Determining Cracking Resistance of Asphalt Mixtures
(2014-04-25)
There is an increasing need in evaluating the cracking resistance of asphalt mixtures as more recycled materials are used in the mixes. A promising method that has been used to evaluate the mixture cracking resistance is ...
Evaluation of Critical and Essential Concrete Highway Bridges in a Moderate Seismic Hazard
(2014-01-21)
The task of this thesis is to determine if the response of critical and essential bridges designed using the AASHTO LRFD Bridge Design Specifications would meet performance requirements when subjected to the moderate seismic ...
Acoustic Emission Testing of Repaired Prestressed Concrete Bridge Girders
(2011-05-04)
Acoustic emission (AE) monitoring has proven to be a useful nondestructive testing tool in ordinary reinforced concrete beams. Over the past decade, however, the technique has been used to test other concrete structures ...
A Technology for Enhanced Control of Erosion, Sediment and Metal Leaching at Disturbed Land Using Polyacrylamide and Magnetite Nanoparticles
(2011-08-25)
Urbanization and human disturbance of land often result in serious soil erosion and releases of fine sediments and soil-bound toxic metals, which can lead to contamination of downstream water bodies and cause water treatment ...
Early-Age Behavior of Lightweight Aggregate Concrete
(2011-11-28)
Early-age cracking can be a severe problem in concrete as it can reduce the service life of the structure. In this project the early-age behavior of concrete was measured, evaluated, and modeled. The early-age stress ...
