Modeling the Risk of Wrong-Way Driving at Freeway Exit Ramp Terminals
(2019-07-23)
Wrong-way driving (WWD) crashes are a critical safety issue on freeways. Although these crashes are rare in nature, they often result in severe injuries and/or fatalities. Typically, exit ramp terminals are the initial ...
Theoretical Modeling and Lateral Load Testing of Driven Steel Pile Bridge Bents
(2019-01-09)
In this thesis, multiple lateral load tests on bridge bents were modeled and performed. FB Multipier models were created for eight load tests: four load tests conducted on a bridge bent under construction in an Alabama ...
Development, Numerical Implementation, and Application of Methods to Simulate Solute Transport Processes in Porous Media Systems
(2019-04-16)
Solute transport in porous media has been the attention of a plethora of studies over the last several decades. This research identifies gaps in existing knowledge within the realm of solute transport in porous media systems ...
Structural Characterization of Recycled Materials at the NCAT Test Track
(2019-11-22)
The functional and structural performance of two pavement recycling techniques: Cold Central-Plant Recycling (CCPR) and Cement Treated Base (CTB) from a Full Depth Reclamation (FDR) process, were evaluated under accelerated ...
Cost-Duration-Based Lump Sum Project Selection Framework Using Stochastic Methods for Design-Bid-Build Resurfacing Projects
(2019-04-04)
The appropriate selection of procurement tools and contracting strategies is a key factor in the successful completion of construction projects and has become an important and growing area of study for both researchers and ...
Drained Residual Strength of Expansive Soils Causing Pavement Distress along Alabama Highway 5
(2019-11-15)
A segment of Alabama Highway 5 (AL-5) located in Perry County, Alabama has been experiencing severe pavement distress that is mostly caused by the behavior of soil beneath the roadway. AL-5 is a farm-to-market road that ...
Effectiveness of pavement preservation treatments on the structural health of the pavement
(2019-11-25)
Pavement preservation treatments are widely applied for surface condition restoration based on different purposes and extent of surface damage. No significant study has been executed on if the preservation treatments provide ...
An Experimental Investigation on Air Pocket Entrapments Caused by Shear-Flow Instabilities in Rapid-Filling Pipes
(2019-08-08)
Rapid filling conditions in closed conduits, such as the case of sewer filling during intense rain events, can lead to air pocket formation. Such formation creates many operational issues in urban water systems, including ...
Reliability-Based Calibration of the Code for Steel Girder Bridges
(2019-02-12)
Accurate evaluation and design of bridge structures can maximize the performance-to-cost ratio, which is one of the most critical aspects in infrastructure maintenance and expansion. The author of this dissertation presents ...
Pore network modeling of reactive permeability
(2019-04-16)
Geochemical reactions, such as those that occur during storage of carbon dioxide in saline aquifers as part of carbon capture and storage (CCS) mitigation techniques or long-term subsurface mineral weathering, can significantly ...
