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) ...
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 ...
Analysis of The Effectiveness of Queue Warning Systems in Freeway Work Zones
(2023-03-14)
Work zone safety and mobility have always been a major concern for state DOTs and transportation professionals. While roadway usage has increased substantially in recent years as the U.S. population and number of licensed ...
A Conceptual Model of Design-Build
(2023-04-03)
Design-build is a project delivery method with roots in the ancient concept of the “master builder” where responsibility for both design and construction reside in one person. Despite the dominance of design-bid-build in ...
The Effect of Initial Curing Temperature and Duration on the 28-Day Compressive Strength of Concrete
(2023-04-19)
The objective of this study was to determine the effect of initial curing temperature and duration on the 28-day compressive strength of concrete. To determine the relationship between initial curing temperature and duration ...
Immediate Deflections of Simply Supported, Bonded, Class T and Class C Prestressed Concrete Beams
(2023-04-17)
Design practice for prestressed members has moved toward allowing partially prestressed members, which are allowed to crack under service loads. To define design requirements, the ACI 318 Building Code explicitly defines ...
Design, Placement, and Laboratory Evaluation of Rejuvenated Cold Recycled Pavement Mixtures
(2023-04-26)
Cold recycled (CR) pavements, the combination of reclaimed asphalt pavement (RAP) and a recycling agent (foamed or emulsified asphalt binder) at ambient temperatures, can provide a sustainable method to rehabilitate, ...
Quantifying the Variability of Production of Asphalt Mixtures through newly implemented Performance Tests for the Wisconsin Department of Transportation
(2023-04-24)
This study aims to determine an appropriate standard deviation of Balanced Mix Design performance tests for Wisconsin specifications based on field-produced mixes. Identifying variability is an essential aspect of the ...
Development of Jobsite Cylinder Curing Practices for the Alabama Concrete Industry
(2023-04-24)
In concrete construction projects, quality assurance test cylinders are made to evaluate the quality of the concrete delivered to a jobsite. In order to accurately evaluate these cylinders, they must be cured according to ...
Assessment of Bioenhanced Back Diffusion and Reductive Dehalogenase Gene Abundance in an Aquifer Cell Packed with Heterogenous Soils
(2023-04-26)
Remediation of chlorinated ethenes can be challenging at complex contaminated sites with low permeability soils acting as secondary source zones due to back diffusion of adsorbed contaminant mass. To better understand how ...
