Filter by Keyword51 report(s) found with materials in the keywords field 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. 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. This report describes a study jointly conducted by the University of Wyoming and the Wyoming Department of Transportation to examine the factors influencing the determination of a subgrade resilient modulus value. The objectives of this study were to first, investigate the importance of several fundamental... This project included two laboratory studies and analytical work dealing with T-beams comprised of a concrete flange connected to a wood beam plus plywood sheathing. Based on the experimental results of tests of 72 slip specimens and 4 full-scale layered T-beams, the mechanical behavior of different... |
