Filter by University45 report(s) found for South Dakota State University According to the 2017 ASCE Infrastructure Report Card (ASCE 2017), 9.1% of the U.S. bridges are structurally deficient. The majority of deficient bridges are in service on low-traffic volume roads, and these bridges should be replaced or repaired for public safety in a timely manner. As an alternative... Several types of tack coats are used in South Dakota for asphalt pavement construction projects. This study was conducted to determine the effects of application rate, surface type, texture, moisture, and freeze-thaw on the early-age performance of three tack coat emulsions applied on four surface types... Transportation access management is defined as systematic control of the design, spacing, operation, and locations of street connections, interchanges, driveways, and median openings on the roadway with the purpose of providing vehicle access while preserving the efficiency and safety of the entire transportation... Stormwater runoff generated in urban areas can increase the risks of flooding and contaminate surface waters. Various contaminants carried by stormwater runoff can negatively affect the water quality of receiving water bodies. Many of the conventional stormwater best management practices are designed... Three bridge sites in South Dakota with streamflow records ranging from 50 to 67 years were selected to compute the histories of pier or contraction scour using the Scour Rates In COhesive Soils (SRICOS) method. Scour depths were computed using a range of soil erosion functions representative of cohesive... 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... The ultimate objective of this project was to determine the structural performance of the dynamic message sign (DMS) bonded with chemical adhesive in terms of ultimate strength and fatigue strength. To achieve this objective, this project first investigated the effects of various parameters (i.e., conditioning... Local governments have an immediate need for low life-cycle cost bridge replacement alternatives. Knowledge of available alternatives and construction planning processes hold potential for South Dakota local governments to replace more structurally deficient local bridges with limited funds. Through... The South Dakota Department of Transportation (SDDOT) has identified a need to reevaluate methods in determining whether granular materials have been compacted to the desired density. Practices of other DOTs indicate additional advantages and disadvantages to various in-situ compaction testing devices.... An evaluation of CRCP was conducted in order to determine the extent of possible corrosion of CRCP on selected interstates in South Dakota. General observations showed there were sections of severe and localized reinforcement corrosion at some crack locations. Crack mapping, chloride tests profiles... |
