The standard bonded-particle models available in many discrete element method (DEM) codes are known to predict unrealistically low values for the ratio of ultimate compressive strength (UCS) to tensile strength (UTS) for concrete. To correct this,...
Sheet piles are geotechnical structural elements often used in canals and rivers for soil retention and scour protection. Short span bridge abutment design in North Carolina and the U.S., for locations near bodies of water, typically uses sheet pi...

Description
According to the Rubber Manufacture Association about 230.7 million scrap tires are generated in the United States every year. Reduction of scrap tire disposal, through recycling and reutilization, has become an important environmental priority. I...
Waste generation rates are increasing so there is a need to determine alternative methods of dealing with waste to accommodate a sustainable future. Polyethylene Terephthalate (PET) plastic represents a large portion of the domestic waste generate...
Mast arm traffic signals and cantilever highway signs have an inverted L-shaped structure and this geometry results in high loading demand to their support foundations when subjected to high wind loading. This MS thesis is motivated by an NCDOT re...
The use of p-y curves is heavily engrained into geotechnical engineering practice. However, even with the prevalent use of p-y curves, these are only used to model the loading portion and not the unloading of a load test or loading demand in the f...
This research involved a comprehensive experimental program was carried out to study compaction characteristics and associated engineering properties of test soils from three actual NCDOT highway projects located within the coastal geologic region...
The generation of electricity from coal-fired power plants continue to be a mainstream approach. It is estimated that about 107 million tons of coal combustion residuals (CCRs) were generated in 2017 in the US (ACAA 2018). This equal amount of CCR...
