Filter by University51 report(s) found for South Dakota State University A study was conducted to develop recommendations for short span concrete structure type selection based on analyses of existing structure costs and performance data from South Dakota roadway systems. Through a combination of data sources, including the PONTIS database, local owner and inspector surveys... Construction of highways usually requires large areas of land disturbance, which may result in accelerated soil erosion. The stormwater runoff from highway construction sites typically contains a large amount of fine particles that are difficult to remove using conventional best management practices.... Precast prestressed double-tee girders are common on county bridges in South Dakota because of the ease of construction, short construction time, and low cost. However, the longitudinal joints of these bridges are rapidly deteriorating, imposing girder replacement after only 45 years of service. Currently... The most common type of bridge on South Dakota local roads is a precast prestressed double-tee (DT) girder bridge. More than 700 DT bridges are currently in-service in South Dakota. Structural detailing, aging, traffic volume, and environmental conditions affect structural performance, integrity, and... The South Dakota Department of Transportation (SDDOT) allows the use of precast double-tee bridges in counties because they are economical and fast in construction. Alternative durable prefabricated bridge systems are needed to provide more options to local governments. The present study was carried... 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... Many laboratory studies have shown erratic flexural strength results among replicate specimens of fiber reinforced concrete (FRC). As a result, repeatability of results was very challenging. Given this issue, it would be very difficult for design engineers to make reliable claims about the performance... An experimental research study was conducted to develop optimized concrete mixtures for jointed plain concrete (JPC) pavements and field evaluation of newly constructed JPC pavement sections along South Dakota highways.
Using South Dakota aggregates, different concrete mixtures were assessed for optimum... 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... Perception-reaction times (PRT) and deceleration rates are critical components in the design of highways and streets. This research has several objectives, including 1) evaluate differences in PRT and deceleration rates between crash and near-crash events, 2) assess the correlation between PRT and deceleration... |
