Filter by Keyword104 report(s) found with design in the keywords field 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... Steel bridges with reinforced concrete substructures and steel superstructures are considered to have superior performance under earthquakes when compared with their reinforced concrete counterpart. Such performance reputation stems from the fact that few steel bridges have been subjected to strong ground... As the population grows and travel demands increase, alternative interchange designs have become increasingly popular. The diverging diamond interchange is an alternative design that has been implemented in the United States. This design can accommodate higher and unbalanced flow and improve safety at... This project studies effective configurations of self-centering devices in the seismic retrofit of curved bridges for control of longitudinal and lateral forces. Reparability of bridge columns is investigated experimentally. A seismic retrofit and repair technique using a Carbon Fiber Reinforced Polymer... 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... Concrete infrastructures in cold areas such as South Dakota tend to experience early deterioration that is mostly triggered by steel corrosion. The corrosion is initiated by chloride penetration through cracks in the concrete. Fiber reinforced concrete (FRC) is known to be a good alternative to conventional... Roadside barriers are the primary structural safety devices on surface roads. They can be made from any material as long as they can absorb the energy involved in an impact scenario. One material that has that potential is Ipe, which is a hardwood material that has relatively high strength compared with... Expanded Polystyrene (EPS) geofoam is a super-lightweight material used in various transportation engineering applications. It has been particularly successful as an ultra-lightweight alternative to earthen, geosynthetic reinforced soil (GRS), and mechanically-stabilized earth (MSE) embankment systems... The ultimate objective of this project was to develop widely accepted recommendations on self-consolidating concrete (SCC) mixture design for its use in WisDOT bridge projects. This project investigated the effects of material constituents on the material properties of trial SCC mixtures made from precasters... |
