Filter by Keyword11 report(s) found with icing in the keywords field Pavements in cold regions of the United States undergo significant accumulation of snow and ice on their surfaces during the extended winter season, leading to reduced skid resistance and increased traffic crashes. Deicers, such as sodium chloride, calcium chloride, and magnesium chloride, have been... 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. The 100+ car rates are a recent innovation in rail grain pricing. Although the rates have been available via contract, a public offering last fall initiated much of the current interest in these larger units. The objective of this study is to provide an informational base that hard red spring wheat market... |
