Identifying And Comparing Key Process Attributes For Sustainable Building Delivery In India And The U.S., Prashanth Palanisamy
Identifying And Comparing Key Process Attributes For Sustainable Building Delivery In India And The U.S., Prashanth Palanisamy
All Theses
India is a rapidly developing nation with the associated brisk pace of construction. More sustainable building practices for construction in India would have social, environmental, and economic benefits. However, the key process attributes for successfully planning, designing, and constructing sustainable buildings in India are largely undefined. Other projects in India would benefit from a rigorous identification of these key process attributes which could help leapfrogging the sustainable building delivery in India to the best available practices.
Sustainable buildings require different delivery processes than traditional buildings; this can lead to process wastes due to unfamiliarity or incompatibility of the processes. These …

Analysis Of Factors Contributing To Roadside Tree Crashes In South Carolina, Vijay Bendigeri
Analysis Of Factors Contributing To Roadside Tree Crashes In South Carolina, Vijay Bendigeri
All Theses
The state of South Carolina has experienced a large number of fatalities and injuries resulting from run off the road tree related crashes. According to 2008 FARS data tree related fixed object fatal crashes in South Carolina (65%) are more than double that of the national (25.8%). Thus, trees are much bigger proportion of all roadside hazards in South Carolina than nationally. In order to achieve a safer roadside which is favorable to the road user, factors contributing to the tree related crashes should be critically analyzed to determine suitable safety improvements.
This research aims at qualitatively and quantitatively assessing …

Hydraulic Modeling To Inform Stream Maintenance Practices In South Carolina, Kelly Owens
All Theses
The Crabtree Canal located in Horry County, SC is the main conveyor of stormwater in a watershed that has undergone considerable urbanization in the last few decades. Evidence of bank instability and inchannel erosion is widely seen in the Crabtree Canal system. Principal sediment inputs are landscape sources and in-channel sources. A study was initiated to provide a working management tool to determine hydrodynamic conditions on the watershed driven by a hypothetical storm event and alternative channel configurations. The management tool comprised of a one-dimensional HEC-RAS model of the Crabtree Canal and was developed to aid the Horry County stormwater …
Moisture Susceptibility Of Asphalt Mixes Using Phosphonylated Recycled Polyethylene, David Herndon
Moisture Susceptibility Of Asphalt Mixes Using Phosphonylated Recycled Polyethylene, David Herndon
All Dissertations
ABSTRACT
Today's asphaltic concrete pavements are expected to perform better even though they are experiencing increased volume of traffic and increased loads over what has been experienced in the past. Research has indicated that the addition of polymers to asphalt binders can enhance many properties of the asphalt pavements to help meet these increased demands.
There remains a serious problem that the addition of polymers to asphalt binders generally does not address. This involves the interfacial cohesiveness of the bond between the aggregate and the binder. Some aggregates are highly hydrophilic (water-loving) while asphalt binders and most polymers tend to …
Synthesis Of Optimal Usage Of Available Aggregates In Highway Construction And Maintenance, Benjamin Skidmore
Synthesis Of Optimal Usage Of Available Aggregates In Highway Construction And Maintenance, Benjamin Skidmore
All Theses
The optimization of the available aggregates for highway construction and maintenance is vital both from an economic and environmental perspective. By not optimizing the aggregate supply project costs escalate as a simple response to supply and demand, and just as important the fact that aggregate is a natural resource and a limited one, it is crucial that is used as efficiently as possible. This paper examines specifically the use of aggregates by the South Carolina Department of Transportation, but can easily be adapted to any state. Through DOT and quarry surveys and an examination of aggregate gradation specifications it was …
Operation Assessment Of Reservoirs In The Savannah River Basin, Travis Yates
Operation Assessment Of Reservoirs In The Savannah River Basin, Travis Yates
All Theses
Hydropower is generated from three reservoirs in the United States Army Corps of Engineer's Savannah District. These reservoirs include J. Strom Thurmond, Richard B. Russell, and Hartwell. Currently, a contract in place specifies that certain amount of energy must be provided to the region. The contract for the hydropower was based upon the critical hydrologic year of 1981. Historically, this was the most severe drought on record and assumed to provide the lowest net inflows for the three reservoirs, thus providing an attainable or reliable energy amount for the system, which suggests a dependable energy yield.
Reevaluating the contract amount …

Reliability Of Light Frame Roof Systems Subject To High Winds, Angelina Gleason
All Theses
Recent hurricane damages have devastated coastal communities and focused national attention on hurricane damage mitigation. Structural damage is one of the most significant impacts of a hurricane. Even small levels of structural damage can result in large economic losses; when gaps open in the roof system, rain water can leak in, ruining the contents of the structure and rendering it uninhabitable although it is still standing. In order to prevent these secondary damages from occurring, a better understanding of the roof system behavior is essential. This research aims to ascertain the behavior of the roof system by determining the influence …
