MPC Research Reports
View AllPrecast/prestressed double tee bridge girders are widely used for accelerated bridge construction on local roads in South Dakota. A common issue among existing double tee bridges in South Dakota is the rapid deterioration of longitudinal joints (shear keyways) between adjacent girders. Deteriorated joints... 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 South Dakota Department of Transportation (SDDOT) currently has a Finite-Element Surface-Water Modeling System for Two-Dimensional Flow (FESWMS-2DH) and Research Management Associates 2 (RMA2) Both programs have the capability to model two-dimensional (2D) flow around structures. The department must... 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... The objectives of this study were to assess geotechnical properties of mine waste amended with fly ash and evaluate reuse of fly ash amended mine waste as road construction material. Three types of fly ash and one type of cement were used as cementitious binder. Natural and synthetic (i.e., laboratory... 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... This research attempts to answer the following fundamental questions: What factors does a transit agency use to choose among alternative TOD locations in a transit network, and what is the relative importance of each factor? It aims to develop a decision support framework that can be used by different... Concrete bridge decks are directly exposed to daily traffic loads and may experience some surface cracking caused by excessive stress or fatigue accumulation, which requires repair or replacement. Among typical bridges in North America, bridge decks are considered the most expensive component to construct... A study was conducted to investigate implementation of accelerated bridge construction (ABC) in South Dakota. Accelerated bridge construction is defined as construction practices that employ innovative techniques to reduce on-site construction time and interruption to traffic. The main objective of this... The high amount of confining lateral steel required by seismic design provisions for rectangular bridge columns can cause steel congestion. The high amount of confining steel may hinder the placement of conventional concrete (CC). Self-consolidating concrete (SCC) eliminates or reduces concrete placement... |
