Precast Full-Depth Deck Panels Supported On Inverted Bulb-Tee Bridge Girders, Michael James Mingo
Precast Full-Depth Deck Panels Supported On Inverted Bulb-Tee Bridge Girders, Michael James Mingo
Electronic Theses and Dissertations
The South Dakota Department of Transportation (SDDOT) currently uses precast double-tee bridge deck systems for many of its county bridges because they are economical and fast in construction. Current bridges are designed for a service life of 75 years. However, many double-tee girder bridges are deteriorating and some need total replacement after 40 years in service. Furthermore, the double-tee bridge system only has one supplier in South Dakota. Alternative durable precast or prefabricated bridge systems are needed to provide more options to local governments when designing a new bridge. Different alternatives will also give local governments more flexibility to select …
Reuse Of Aqueous Waste Streams For Transportation-Related Applications, Gregory L. Hansen
Reuse Of Aqueous Waste Streams For Transportation-Related Applications, Gregory L. Hansen
Electronic Theses and Dissertations
Aqueous waste streams produced from commercial, industrial, and municipal processes may be potentially reused for transportation applications. The objectives of this project were to identify potential transportation-related applications for aqueous waste streams available in South Dakota, develop guidance for the beneficial reuse of aqueous waste streams, and evaluate the reuse of MIEX® brine generated by the Watertown Municipal Water Treatment Plant (WMWTP). This study identified many aqueous wastes from municipal water and wastewater treatment facilities, industrial and agricultural processes in South Dakota that can be potentially used for ice and dust control. Beneficial reuse of these waste streams requires a …
