A Study of Driver Behaviors at Unsignalized Intersections Using SHRP2 Naturalistic Driving Study Data and Field Observed Conflict Data
(2022-01-10)
Unsignalized intersections on divided highways with wide medians (>30 ft) have the potential for severe crashes due to numerous conflict points and high speed. Drivers making minor road left turns have to make multiple ...
Early Characterization and Performance of Flexible Pavements Utilizing Asphalt Additives
(2022-04-25)
Asphalt additives have been utilized for years to modify the performance of flexible pavements. They have the potential to lead to long-lasting and sustainable asphalt pavements. In recent years, several new categories of ...
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 ...
TWO-PART MASTER’S THESIS PART ONE: EVALUATION OF COOL ROOF REFLECTIVITY IMPACTS PART TWO: SURFACE SKIMMER FLOW RATES
(2022-05-04)
PART ONE: Cool roofs attempt to lower the temperature of the roof surface so that the interior of buildings can be cooled using less energy. Light color surfaces, white being the coolest color, are much cooler than darker ...
Improvements in Stormwater Detention Technologies through Large-Scale Testing Techniques
(2022-05-05)
Due to urbanization and a changing climate, stormwater management has become increasingly discussed, regulated, and researched. In many areas of the United States, one effect of climate change has taken form in more intense ...
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 ...
Rheological and Chemical Evaluation of Aging Resistant Binder Technologies
(2022-05-02)
Asphalt binder is a dark-colored cementitious hydrocarbon material, with a complex chemical composition that is heavily dependent on crude oil source and manufacturing process. Binder chemistry has been modelled as a ...
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. ...
Novel Methods for Adding Rejuvenators in Asphalt Mixtures with High Recycled Binder Ratios
(2022-07-25)
Most asphalt mixtures being placed in the United States currently use RAP as not only a sustainable method of building pavement surfaces but also an economical one. The stiffness and brittleness of the aged RAP binder, ...
A ‘Concentrate-&-Degrade’ Technique for Cost Effective Adsorption and Degradation of Per-and Polyfluoroalkyl Substances in Water
(2022-07-25)
The overarching goal of this research is to develop and test a new class of carbon-photocatalyst composites for enhanced adsorption and destruction of per- and polyfluoroalkyl substances (PFAS) in water and field water. ...
