MPC Research Reports Filter by University109 report(s) found for Colorado State University This report describes a research project conducted at Colorado State University to evaluate the effect of road dust suppression on unpaved road maintenance schemes. A field-based method was used to measure the effect of road soil physical characteristics on the effectiveness of some of the commonly... Universities and transit agencies across the United States have been finding innovative new ways of providing and financing mobility services on and around university campuses. Many transit agencies are providing substantially more service and moving substantially more riders than their counterparts... A three-span, open deck timber trestle railroad bridge had been previously field load tested. The prior testing program was done in cooperation with the Transportation Technology Center, Inc., a subsidiary of the Association of American Railroads. The bridge was subjected to static and moving train loads... 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 variety of portable safety and security barriers for directing traffic (public events, sports facilities, etc.), and securing private and public locations against access (court houses, schools, etc.) have been developed. Some higher capacity systems have been developed for use on and around high speed... A laboratory test program was conducted on full-scale specimens replicating the main elements of a timber trestle railroad bridge chord. Previous field load testing had been done and was complicated by differing site-specific conditions. The purpose of the ongoing laboratory study described is to compare... 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 concept of combining wood and concrete in layered composite bridge deck was investigated. A shear key/anchor detail recently used in Europe to construct floors in office buildings was adapted for this study. This connection detail provides the interlayer shear transfer between the layers. Laboratory... The field of transportation is rapidly becoming a popular career choice for undergraduate engineering students. Many work opportunities are available in the area of transportation including computer software analysis, field testing, and consulting. Unfortunately, these opportunities are not always accessible... 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...
