Ensuring Safe Drinking Water for the Northern Corridor of Haiti Through Expanded Testing Services
(2022-12-01)
Due to the lack of potable piped water, drinking water access is a concern in Haiti. Families often gather water for household use from private wells, springs, and rivers. These local water sources are often of unknown or ...
Evaluating alternatives for the implementation of Curve Number in SWMM for an urbanized watershed
(2022-11-27)
Modeling hydrological abstraction, particularly infiltration, in urbanized areas is a complex task. Without field validation data, researchers and engineers often rely on readily available methodologies on semi-empirical ...
Evaluation of Laboratory and Field Produced Cold Recycled and Full Depth Reclaimed Asphalt Pavement Materials
(2021-05-18)
Cold recycling (CR) and full depth reclamation (FDR) are sustainable processes of
recycling existing pavement materials to construct stronger stabilized base layers. The recycled
asphalt pavement’s materials vary in ...
Evaluation of Nondestructive Test Methods for Concrete Bridge Deck Condition Assessment
(2021-07-14)
To facilitate locating subsurface concrete bridge deck defects and determining their
corresponding severity, departments of transportation are switching to nondestructive
test (NDT) methods. However, the difficulty in ...
Evaluation of Nondestructive Testing Methods to Assess the Condition of Concrete Bridge Decks
(2021-08-02)
Bridges are critical parts of the transportation infrastructure in the United States and throughout the world. During their lifecycle, reinforced-concrete bridge decks can experience distresses and defects in the form of ...
Evaluation of Pile Load Testing State of Practice for ALDOT Projects
(2021-12-01)
A database of driven piles taken from archives of the Alabama Department of Transportation (ALDOT) was created for the purpose of evaluating the pile load testing state of practice for ALDOT. The dataset was derived from ...
Evaluation of Shear Tab Connections as Supplemental Energy Dissipators
(2022-11-04)
As structural engineering practice moves from life-safety to functional recovery after a significant seismic event, taking advantage of structural components to enhance the energy dissipation of a structure will be important. ...
Experimental Testing and Analysis of S50 Beam with Finite Element Modeling of Splice Connection
(2021-12-08)
Large Area Maintenance Shelters, LAMS, are commonly used as deployable shelters by the US Air Force to store and maintain equipment. This work is specific to the LAMS located at Tyndall Air Force Base manufactured by ...
Exploring Targeted Long-Distance Travel Survey Sampling Frame Approaches to Support Travel Survey Collection
(2022-08-05)
Long-distance travel continues to grow in economic, environmental, and infrastructural importance. To inform policy, infrastructural funding, and travel demand forecasting, detailed travel survey findings are needed at the ...
Finite Element Modelling of Large Area Maintenance Shelters and Comparison to Experimental Results
(2021-08-16)
Large area maintenance shelters (LAMS) are used as temporary structures by the United States Air Force to provide shelter for helicopters, tanks, wheeled vehicles, and aircraft. There are several different brands of LAMS ...
Forensic Analysis of a Large Volume Rack Building Impacted by Hurricane Michael (2018)
(2021-12-02)
Metal building systems (MBS) are extremely common and frequently used in commercial, industrial, and warehouse applications thus serving critical roles in local economies. Damage sustained to these buildings through extreme ...
FULL-SCALE MECHANISTIC AND PERFORMANCE INVESTIGATION OF A FLEXIBLE PAVEMENT WITH A STABILIZED FOUNDATION
(2021-06-21)
The current study aimed to develop a mechanistic understanding of the behavior of flexible pavements with stabilized foundations through full-scale testing, instrumentation, and simulation. In pursuit of this objective, a ...
Identifying Effectiveness of Engineering Traffic Control Devices for Wrong-Way Driving from the Driver Behaviors Perspective
(2023-01-09)
This dissertation aims to identify the effectiveness of engineering traffic control devices for wrong-way driving (WWD) from a driver behavior perspective, which contains two tasks: i) WWD fatal crash analysis, and ii) ...
Impact of overloaded vehicles on bridges
(2021-08-03)
Excessive weight and a growing number of overloaded vehicles can cause an accelerated consumption of bridge service life. Therefore, there is a need to control the operation of heavy traffic. This study considered the ...
Improvements in Construction Stormwater Treatment using Flocculants
(2022-05-03)
Construction stormwater runoff constitutes an increased risk for downstream water bodies if unmanaged sediment-laden discharge exits a construction site. Federal and state regulations emphasize the significance of erosion ...
