Analysis on Structural Modeling for Recycled Asphalt Pavement used as a Base Layer
(North Dakota State University, 2015)
Reusing RAP in the base layer became a common practice in the last decade. However, some crucial issues must be resolved to succeed in using RAP satisfying the standard specifications as a base layer. The most important ...
Structural Enhancement Utilizing Smart Materials: Experiments and Applications Involving Piezoelectric Actuators and Shape Memory Alloys
(North Dakota State University, 2015)
Smart materials, within the realm of structural engineering, are mainly used as either sensoric mechanisms or as structural damping mechanisms. For the most part, structural enhancement utilizing smart materials is not ...
Application of Damage Mechanics to Describe the Behavior of Concrete under Fatigue and Freeze-Thaw Processes
(North Dakota State University, 2015)
Concrete has been used in dams, bridges, and highway pavements in which freeze-thaw process and cyclic loading are important factors affecting its mechanical behavior. Damage caused by frost expansion is a primary concern ...
In-Line Fiber Optic Sensing System for Pipeline Corrosion Detection
(North Dakota State University, 2015)
To understand the impact of corrosion on metal on-shore buried transmission pipeline, which is one of the most critical damages, corrosion evaluation plays an important role. An effective approach for real-time in-line ...
Damage Localization of Slab-on-Girder Bridges Through Vibration Characteristics
(North Dakota State University, 2015)
An incompletely documented bridge 09-125-16 in Cass County, ND was tested by Bridge Diagnostics, Inc. (BDI). A Grillage numerical model is created with their field data to simulate the bridge responses due to traffic loads. ...
Coating of NZVI Particles With Modified Starch: Colloidal Stability and Nitrate Reduction Studies
(North Dakota State University, 2015)
Nanoscale-zero valent iron (NZVI) is an effective groundwater remediation media because it can quickly reduce and absorb contaminants. However, NZVI quickly agglomerates in aqueous systems, reducing its remediation capacity. ...
Design of Polymer Materials with Lower Environmental Impact
(North Dakota State University, 2015)
In today’s world of emerging advanced materials, environmental impact of new technologies, as well as already well-established products, is of utmost importance. Environmental safety is as crucial as performance/price ratio ...
The Application of Electroanalytical Techniques to the Study of Coating Systems
(North Dakota State University, 2015)
Electroanalytical techniques are often employed to augment standard practices utilized to study and characterize coating performance on metal substrates, yielding information that is not provided by standard coating analysis ...
Electrochemical Investigation of Powder Coatings and Their Application to Magnesium-Rich Primers For Corrosion Protection
(North Dakota State University, 2015)
Corrosion is the decomposition of metal and metal alloys which threatens the integrity of manmade
structures. One of the more efficient methods of delaying the corrosion process in metals is by
coatings. In this work, ...
Synthesis, Characterization, and Applications of Electroactive Polymeric Nanostructures for Organic Coatings
(North Dakota State University, 2015)
Electroactive polymers (EAP) such as polypyrrole (PPy) and polyaniline (PANI) are being explored intensively in the scientific community. Nanostructures of EAPs have low dimensions and high surface area enabling them to ...
