(2021-11-29)
This dissertation investigates two innovative applications of the Second Strategic Highway Research Program Naturalistic Driving Study (SHRP 2 NDS) data: (1) freeway interchange deceleration lane design and (2) work zone ...
Laboratory and Field Characterization of Additive-Modified Asphalt Concrete Mixtures
(2023-11-27)
There is a need for a more rapid system of evaluation and implementation for new and existing
asphalt additives, especially due to the prohibitive cost of full-scale performance evaluations. To
help to meet this need, ...
Laboratory and Field Measurements of Moisture Content and Bulk Electrical Conductivity of Subgrade and Base Course Materials
(2023-08-04)
Moisture content can impact the resilient modulus of pavement base course and subgrade layers. Given its influence on the post-inundation resilient moduli of the coastal pavement and base course and subgrade layers, it is ...
Laboratory Evaluation of Heat Exchange Between Superheated Virgin Aggregate and Reclaimed Asphalt Pavement Material
(2021-07-27)
The most common method of Reclaimed Asphalt Pavement (RAP) material processing in the production of Hot Mix Asphalt (HMA) in the United States is by using cold feed recycling. Superheating the virgin aggregates by hot gas ...
Land Application of Treated Wastewater within the Black Belt of Alabama
(2023-08-09)
The Black Belt of Alabama is a region of the United States that has seen its population decrease and poverty rise over the last century. The Black Belt was a thriving part of Alabama due to the rich, fertile soil. The dark ...
Lean-On Bracing Refined Design Methods and Field Assessment
(2024-04-15)
Cross-frames are critical for the stability of steel bridges during construction and play a significant role in completed bridges. Historically, brace locations have been regions of fatigue concerns, and each brace requires ...
Leveraging Automation in Data Enhancement and Quality Control Protocols for Post-Windstorm Reconnaissance Data
(2021-04-30)
Extreme windstorms cause loss of life, major financial losses, and disrupt community well-being. Post-windstorm field reconnaissance is one of the traditional methods used to collect data about these natural hazards. The ...
Life Cycle Assessment of a Steel-Timber Composite Structure Comparison to an Established Structural System
(2023-01-11)
The building and construction industry drives global energy use and emissions. With climate change mitigation being a forefront topic of concern, the building and construction industry has a responsibility to alleviate its ...
Load Rating Corrugated Metal Culverts with Shallow Soil Cover
(2023-05-01)
Culverts under existing roadways that do not meet current cover requirements are common. Even though they may have performed without any issues for decades, rating of many of them using current specifications and methodologies ...
MACHINE LEARNING BASED MINERAL CHARACTERIZATION FROM PORE TO CORE SCALE AND IMPLICATIONS FOR GEOCHEMICAL REACTIVITY
(2022-11-29)
Geological formations have great potential for large-scale carbon sequestration to reduce the net rate of increase in atmospheric CO2. In these systems, CO2 is injected into formations and mineralized through geochemical ...
Mixture Sampling and Determination of Asphalt Binder Content for Slurry Surfacing Systems
(2022-07-25)
Slurry seals and micro surfacing are two of the main preventative maintenance methods used by state and local agencies. However, there is a lack of methods for quality control/quality assurance for slurry surfacing systems. ...
Modeling Exhaust-Generated Aerodynamic Pressure Loads on Airfield Matting Repair Systems
(2021-11-30)
Airfield matting systems are commonly used for rapid repair of damaged runways to facilitate continuity of critical operations. Under normal service conditions, matting repair systems are subject not only to wheel loads ...
A Multi-Attribute Utility Theory Analysis of Alternative Erosion Control Materials to Class 2 Riprap in Alabama
(2022-05-04)
Riprap is an extremely common material for construction projects and often assumed to be the most cost-effective option for channel armoring. However, a study done by Auburn University found that in the state of Alabama ...
Novel Methods for Adding Rejuvenators in Asphalt Mixtures with High Recycled Binder Ratios
