The use of precast concrete in bridge construction has been abundant in recent years because of its efficiency and superior quality control. Precast components are connected at the bridge site to reduce construction time and traffic disturbance. The Grouted Splice Sleeve (GSS) connection provides good...

A mechanical bar splice, also known as bar coupler, is an alternative to the traditional lap splicing to connect bars in reinforced concrete (RC) structures. Even though mechanical bar splices can be used as new precast column connections to accelerate bridge construction (ABC), the use of bar couplers...

Compared with conventional lap splicing, mechanical splicing is an alternative method of connecting bars in reinforced concrete (RC) structures, and is used mainly to reduce bar congestion in joints. Recently, mechanical bar splices, which are also referred to as bar couplers, have been used in laboratories...

A research study was conducted by South Dakota State University in cooperation with the South Dakota Department of Transportation (SDDOT) to assess applicability of the American Association of State Highway and Transportation Officials (AASHTO) design calculations for the dynamic ice loads on bridge...

Over the years, Fiber Reinforced Polymer (FRP) composites have gained popularity in transportation infrastructure as a material able to restore and increase the capacity of existing concrete elements. Properties such as a high strength to weight ratio, non-corrosive nature, durability, and high malleability...

The main objective of rural roadway pricing is revenue generation, rather than elimination of congestion externalities. This report presents a model that provides optimum tolls accounting for pavement deterioration and economic impacts. This model contains multiple components, because imposing tolls...

Innovative lane management offers the opportunity to levy fees for the premium road space. Express Lanes in Utah offer road users reduced journey times for a fee. The Utah Department of Transportation (UDOT) has converted the High Occupancy-Vehicle (HOV) lanes on Interstate 15 (I-15) from 600 North Street...

This research focuses on the long-standing relationship between the rail industry and production agriculture. It will investigate the differential effects of policy change, considering factors that have influenced pricing service for corn, wheat and soybeans in a deregulated rail industry.

This study examines the cost implications of mergers and competition over existing rail lines by testing for the condition of cost subadditivity. That is, can industry output be provided at a lower cost by one firm than by more than one firm?

This analysis is largely based on received theory of firm behavior. How will an individual transportation firm react to changes in the logistical system if the four dams are breached? The collective action of like firms will result in changes in the industry, which will reveal much about the potential...
