A project to study the pier moment-rotation behavior of compact and non-compact high performance steel HPS70W bridge I-girders was conducted at Colorado State University in the context of examining two restrictions for inelastic design of steel bridge girders in the current edition of the AASHTO LRFD...

A field load test program was conducted to evaluate three open-deck timber railroad trestle bridges. The bridges included part of a 31-span bridge, a 4-span bridge with skewed interior bents and a 3-span bridge. Plies of the chords of the bridges were evaluated non-destructively for material properties...

The present research suggests a new approach to the use of composite materials technology for repair of timber structural members. Due to the small aspect ratio of the typical railroad bridge span timbers, stiffness degradation can be related to decrease in the beam's shear performance. To rejuvenate...

This research considers the influence of different construction materials on the dynamic impact factor of bridges. The general concept of the dynamic impact factor and typical evaluation methods are reviewed.

Evaluation of Pavement Shoulders (May 1999, MPC-99-101)

In this study the researchers examined the effect of pavement shoulders on the safety and structural strength of highways in Wyoming. The costs of adding shoulders to various types of highways also was examined. The study consisted of selecting representative highway sections, collecting accident data...

Public concern about hazardous materials, such as agricultural fertilizers, has steadily increased. Thus, North Dakota created Recommended Management Practices for The Primary and Secondary Containment of Fertilizers (RMP). This study attempted to determine how compliance with RMP guidelines affects...

This report develops a baseline inventory of rail hazardous commodities that originate in, terminate in, or pass through Region 8 (which includes the states of Colorado, Montana, North Dakota, South Dakota, Utah and Wyoming). The inventory also includes a set of interregional tables that summarize hazardous...

The purpose of this paper is to evaluate and make recommendations about the current inventory management system at TMI Systems Design Corporation. The goal is to apply a logistics management perspective to current procedures.

This paper examines the effectiveness of applying chip seal friction courses in reducing accidents on low volume, rural roads. Chip sealing data from District 3 of the Utah Department of Transportation were used to examine accident rates before and after applying chip seal. Although accident rates generally...

This analysis is primarily focused on the materials management issues associated with the procurement of wheat straw for a processing plant in Pickert, North Dakota.
