Fiber reinforced concrete has been used in bonded resurfacing overlays and assumed to have improved performance, as well as cost-effective. The benefit of improved toughness by incorporating fibers has proven to reduce cracking, yet other deformation characteristics and the bond interaction to the underlying...

Culverts are an important asset that tackle a simple task – to convey storm water through roadway sections. From regression equations to outlet discharge, this presentation will walk through the demands of a culvert system and explore various design criteria. Topics to be reviewed: Regression...

The focus of the class will be curb ramps in the public right-of-way. Design elements such as width, cross slope, grade and surface necessary for achieving accessibility in the public right-of-way will be reviewed. The requirements for detectable warning surfaces at the base of curb ramps will be described....

Introduction Background and Motivation Characteristics of Non-Motorized Users: pedestrians (able-bodied and disabled) and bicyclists Designing Roads/Streets for All Users Design Controls: speed, design vehicle, sight distance, horizontal and vertical alignment, access management, and accessibility...

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...

This presentation will focus on the state of the practice with digital signatures and the e-Construction advancements. Digital signatures on documents, plan sheets, and 3-D models are becoming more commonly used in the DOTs. This practice has expedited design, construction and decision making in our...

This presentation will concentrate on design and construction processes of the Minnesota I-94/MN 75 interchange in Moorhead, Minnesota. A primary designer and construction representatives will give overviews of these two major stages in delivering the project. The design presentation will include...

A drilled shaft, also referred to as drilled piers, caissons or bored piles, are deep foundation solutions used to support structures with large axial and lateral loads by excavating cylindrical shafts into the ground and filling them with concrete. The purpose of this presentation is to provide an overview...

This presentation will cover the research conducted by University of Minnesota Duluth (UMD) for Minnesota DOT to evaluate various asphalt patching methods. The research lead to a simple decision matrix and best practices manual for Minnesota field staff. The presentation will also cover an ongoing crack...

This presentation will cover research conducted by South Dakota State University under the Mountain-Plains Consortium Project 437 and with additional funding from SDDOT. There is little guidance for SDDOT pertaining to the use and testing of FRC. There is also lack of information about new fiber products...
