Life Cycle Cost Analysis Of Pavements: State-Of-The-Practice, Zeynep Guven
Life Cycle Cost Analysis Of Pavements: State-Of-The-Practice, Zeynep Guven
All Theses
Life Cycle Cost Analysis (LCCA) is performed by transportation agencies in the design phase of transportation projects in order to be able to implement more economical strategies, to support decision processes in pavement type selection (flexible or rigid) and also to assess the relative costs of different rehabilitation options within each type of pavement. However, most of the input parameters are inherently uncertain. In order to implement the LCCA process in a reliable and trustworthy manner, this uncertainty must be addressed. This thesis summarizes a through research that aims at improving the existing LCCA approach for South Carolina Department of …
Influence Of Socio-Economic And Demographic Factors On Crashes In Rural South Carolina At Sub-County Level, Sunil Jakhadi
Influence Of Socio-Economic And Demographic Factors On Crashes In Rural South Carolina At Sub-County Level, Sunil Jakhadi
All Theses
State of South Carolina ranks high in the fatality rates. The state is a predominately a rural state with more percentage of rural roads. This research focuses on the statistical variation of crash rates between the county and block-group, especially rural once to the state. Also, it focuses on the possibility of various socio-economic and demographic characters influence on the high crash rates particularly in rural South Carolina.
Crash database for the year 2004 was acquired from South Carolina Department of Transportation and was processed by the research team at Clemson University. This processed database was imported into GIS. Spatial …
Effect Of South Caroline Belt Law On Safety Belt Use, Sourabh Patki
Effect Of South Caroline Belt Law On Safety Belt Use, Sourabh Patki
All Theses
A number of factors and accessories help save lives and prevent injuries to road users, yet safety belts have become synonymous with automobile safety today, unlike any accessory before or since their introduction in automobiles. However, the scientific advances in automobile safety, followed by the acceptance of the necessity for safety in automobiles by both the manufacturers and the population, finally leading to the introduction of safety features and their incorporation within the laws occurred over a much longer span, continuing even today. Today's Safety movement aims at increasing safety belt using an awareness campaigns, accompanied by enforcement. Safety belt …
Best Practices For Developing The Engineer's Estimate, Karl Niedzwecki
Best Practices For Developing The Engineer's Estimate, Karl Niedzwecki
All Theses
The research project 'Best Practices for Developing the Engineering Estimate' was executed by Clemson University on behalf of the South Carolina Department of Transportation (SCDOT). The primary objective of this research project was to investigate the strengths and weaknesses of two types of estimating methods being utilized today by state department of transportations (DOT) nationwide. These two types of estimating methods are the unit cost line item approach, which the SCDOT utilizes, and the cost-based estimating approach. This research report identifies accuracy obtained, resources expended, and methodologies utilized when implementing either type of estimating approach. This was done so the …
Evaporation Estimation Using A Floating Pan, Michael Klink
Evaporation Estimation Using A Floating Pan, Michael Klink
All Theses
Almost all regions in the United States must accurately estimate evaporation to have effective water management programs. The purpose of this study is to develop a better method for measuring evaporation. Lake evaporation along with meteorological data are measured directly from a floating pan. The floating pan is specifically designed to account for one of the most sensitive parameters of evaporation, the water surface temperature, which the design achieves. However, other design factors such as air movement, solar radiation, stability, heat transfer, wave action, water level range, and site location were also taken into consideration. The evaporation measured from the …
Optimizing The Project Team's Contribution To Business Objectives, Chad Rowland
Optimizing The Project Team's Contribution To Business Objectives, Chad Rowland
All Theses
The traditional expectations of the project team are for the processes of engineering, procurement, construction, and start-up to be expertly administered. However, these performance criteria can be satisfied yet still not meet the ultimate business needs of the owner. The purpose of this thesis was to determine ways to improve the likelihood of achieving owner's business objectives. Fifty-one questionnaire survey forms were analyzed to obtain data for thirty-three pre-project planning activities. A data analysis concluded with a degree of statistical significance that for thirteen of the thirty-three activities, the more successful projects, as defined by the satisfaction of the business …
The Effects Of Calcium Magnesium Acetate Deicers On Portland Cement Mortar Bars, Jeffrey Davis
The Effects Of Calcium Magnesium Acetate Deicers On Portland Cement Mortar Bars, Jeffrey Davis
All Theses
This thesis involves the investigation of the effects of Calcium Magnesium Acetate (CMA) deicers on Portland cement mortar bars. In addition to mass-loss, length change, pulse velocity and soak solution pH, the thesis also contains a rigorous chemical analysis of the mortar completed at the National Institute of Standards and Technology (NIST) in Gaithersburg, MD. The research completed at NIST was done using a technique known as X-ray Mapping. The X-ray techniques were employed to determine the exact nature of the damage caused by CMA. The thesis is a combination of two papers, on the physical effects of CMA and …
