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...

 

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...

 

Most roads in the City of Madison, South Dakota were built more than 30 years ago, with chip seal as the primary maintenance practice. However, such treatments only provide temporary solutions to the surface and do not improve the structural deficiencies. To prevent accelerated pavement deterioration...

 

Providing acute medical care outside of the hospital, Emergency Medical Services (EMS) is crucial in rural environments where hospitals are not close by and are difficult to access. This study used the National EMS Information System (NEMSIS) South Dakota data to exemplify the establishment of data-driven...

 

Engineering economic analyses (EEA) apply economic methodologies to engineering problems for decision-making support. When conducting an EEA, interest and inflation rates are the two critical factors. Using inappropriate values for interest and inflation rates could affect decision-making, such as unfairly...

 

Improved emergency medical services (EMS) will impact traffic safety and public health in rural communities. Better planned, designed, and operated roadway networks that connect hospitals with communities in need will enhance EMS performance. To provide safe, timely and quality services, it is necessary...

 

In this study, the current SDDOT Road User Cost methodology and associated unit costs were evaluated and changes were implemented to the methodology to allow for a more complete analysis that aligns with the needs of each department and their use of RUC. The methodology was used to construct a worksheet...

 

The use of self-consolidating concrete (SCC) for the manufacture of precast structural elements provides the benefits of increased rate of production, reduced labor needs (safety), and enhanced product quality. The same benefits apply to cast-in-place construction, especially with closely spaced reinforcing...

 

Given the sparsely distributed crashes across various highway systems, this study designed an empirical Bayes (EB) based sliding window technique within a spatial context. By examining roadway safety spatially, the safety analysts are able to account for high-risk locations completely within longer predefined...
