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. ...
Electrochemical Investigation of Corrosion Resistance of Weldments in Steel Bridges
(North Dakota State University, 2015)
Welding is commonly used for connecting steel components in steel bridge fabrication and construction. Welding processes change the microstructures, properties of surrounding steel and its surface texture. In this study, ...
Explore Accelerated PCC Pavement Repairs Using Metakaolin-Based Geopolymer Concrete
(North Dakota State University, 2015)
In order to adopt geopolymer concrete as a pavement repair material due to its better durability, splitting and slant shear tests are performed. Effect of curing time, degradation of the pavement concrete under different ...
Characterization of Activities of Crumb Rubber in Interaction with Asphalt and its Effect on Final Properties
(North Dakota State University, 2015)
Recycling of millions of scrap tires produced everyday is crucial challenge encountered by waste management systems. Recycling tire rubbers in form of ground tire rubber, known as crumb rubber modifier (CRM), in asphalt ...
