The understanding of Bender Element mechanism and utilization of Particle Flow Code (PFC) to simulate the seismic wave behavior is important to test the dynamic behavior of soil particles. Both discrete and finite element methods can be used to simulate wave behavior. However, Discrete Element Method (DEM) is mostly suitable, as the micro scaled soil particle cannot be fully considered as continuous specimen like a piece of rod or aluminum. Recently DEM has been widely used to study mechanical properties of soils at particle level considering the particles as balls. This study represents a comparative analysis of Voigt and Best …

Anyone who has ever attempted to remove a layer of ice from a roadway or sidewalk by plowing or shoveling knows it is no easy task when the ice is firmly bonded to the asphalt/concrete surface. Winter anti-icing/deicing operations are moral choices that mankind has made to combat winter storms. This research is aimed at evaluating the macro and nano structural impacts of (anti-icing/de-icing) salt on aged and unaged asphalt binders. The macro structural impacts focused on the rheological and creep properties, and the nano structural impacts focused on the surface topography, adhesion force, and modulus of asphalt binders. Rheological …

Warning Systems Evaluation For Overhead Clearance Detection, Clayton Rogers
GS4 Georgia Southern Student Scholars Symposium
The accurate detection of road vehicle heights is a need that arises in departments of transportation across the nation. Usually, this dimension is required to solve various transportation issues. In particular, numerous bridges in the state of Georgia have been affected by repetitive crashes of tall vehicles against their structural elements. As an example, a recent inspection report of the Houlihan Bridge over the Savannah River documents damages resulting from numerous hits by overheight vehicles. This case emphasizes the urgency of finding preventive measures. To address this issue, a number of solutions are investigated. The known methods of vehicle height …

GS4 Georgia Southern Student Scholars Symposium
Construction and demolition waste accounts for 52 % of the total landfilled space. While many advances in disassembly sequencing in buildings have been proposed to recycle concrete, steel, and tile associated with construction and demolition waste, the insulation contained within every building persists as a significant environmental challenge to recycle and reuse. Adding to this problem is the fact that when petroleum based foams are incinerated, it emits carbon monoxide, nitrogen oxides, isocyanine, acrylonitrile, and hydrogen cyanide in levels exceeding those allowed by the EPA, posing a significant threat to the environment and human health. Design for Disassembly (DfD) approach …

GS4 Georgia Southern Student Scholars Symposium
In this presentation the special utility of the LabVIEW Virtual Instruments published as HTML files is documented and discussed. The Virtual Instruments (LabVIEW programs) created using the software's web publishing tool can be used to complement the effectiveness of the classroom instructions and extend the reach of engineering researchers in more effectively conducting laboratory and field experimentation. The Virtual Instruments (VIs) created as web documents can be placed on a web-server and made available to users at remote locations. These files can enhance the collaborations and interactions among individuals at these stations. For example, the created VIs for a course …
