Laboratory Scour Testing of Hard Cohesive Soils in Alabama
(2014-01-09)
Establishing scour parameters in order to estimate the loss of soil adjacent to bridge piers is a crucial element in the design of highway bridges crossing over rivers and streams. Although there are numerous design criteria ...
An Analysis of the Municipal Solid Waste Permitting and Recycling Programs of the State of Alabama
(2013-11-08)
In the past half century solid waste policy has changed significantly as public awareness and the realization of potential environmental hazards of landfills has grown. The State of Alabama has recently begun to experience ...
Investigation of the Use of Steel Intermediate Diaphragms and Temporary Bracing Alternatives for Prestressed Concrete Girder Bridges
(2014-04-23)
Common in bridge construction today, diaphragms are placed transverse to the girders, connecting adjacent girders to provide stability and transmit loads. Diaphragms are defined as either end diaphragms – used at the ends ...
A Study of the Thermal Interactions of Sustainable Asphalt Concrete Pavements
(2013-12-04)
A study of the thermal interactions of select sustainable technologies, such as reclaimed asphalt pavements (RAP), recycled asphalt shingles (RAS), ground tire rubber (GTR), and foamed asphalt in cold recycled materials ...
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 ...
