All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
In the scope of transportation asset management, the maintenance and rehabilitation (M&R) performed on asphalt roads at the local government level requires careful planning and intelligent use of limited funding. For this reason, a Pavement Management System (PMS) is incorporated and used as a tool for local government leaders to make the best decision given their annual budget. The PMS process is a repeatable process which consists of determining present day pavement condition, evaluating future deterioration, performing an economic analysis of possible M&R treatments and finally implementing a proper M&R plan to keep the asphalt pavement network in good condition. …

The objective of this study was to determine the economic viability of solar powered water pumping and desalination systems for agriculture. Growing global demand for agricultural production has put increased pressure on limited freshwater resources in various locations around the word. Many areas have low quality groundwater resources that have not been utilized for agriculture due to limited availability to electricity, high operational costs of diesel generators and the economics associated with water pumping and processing. Reverse osmosis is a desalination technology that removes salts and other minerals from low-quality water, making it fit for drinking or irrigation. Reduced costs …
