Creep and Shrinkage Properties of Lightweight Concrete Used in the State of Iowa, HR-136, Phase I, 1968

In February of 1968 a cooperative research project by the Iowa State Highway Commission (Project No. HR-136) and the University of Iowa, Iowa City, Iowa was initiated in order to determine experimentally the creep and shrinkage characteristics of lightweight-aggregate concrete used in the State of Iowa. This report is concerned with Phase 1 of the Project as described in the Prospectus for the project submitted in November of 1967: "The State Highway Commission is planning to conduct pilot studies in prestressed-lightweight structures fabricated with materials that are proposed for use in bridge structures in the near future. Thus, Phase will have as its immediate objective, investigating the materials to be used in the above mentioned pilot studies.” (1) The work described in this report was also carried out in conjunction with a second cooperative project: "Time-Dependent Camber and Deflection of Non-Composite and Composite Lightweight-Prestressed Concrete Beams" (Project No. HR-137).

The Draft EIS, which was distributed in July 2002, is incorporated by reference herein and made a part of the Final EIS.

Highway Location Reference Procedure Project, 1990

The purpose of the proposed Highway Location Reference Procedure is stated in the contract as follows: "Establishment of a highway network locational reference process that will primarily allow for the proper correlation of pavement management data, and secondarily provide the basis for other existing and future data base integration and for the planned Iowa DOT Geographic Information System. In addition, the locational reference process will be able to correlate network applications with a statewide spatial location method to facilitate the relationship of Iowa DOT data to that of other agencies and to allow for the graphic display of the network in map form." The Design Specifications and Implementation Plan, included in this Final Report, are intended to provide the basis for proceeding with immediate development and implementation of the pavement management system. These specifications will also support the future Iowa DOT implementation of other integrated data bases and/or the planned Geographic Information System.

The Keokuk & Hamilton Bridge : Keokuk, Iowa - Hamilton, Illinois, 1982

The Keokuk & Hamilton Bridge is one of three remaining in Iowa that were designed by Ralph Modjeski, one of this country's premier early 20th century bridge engineers. The eleven-span, double-deck steel superstructure was built in 1915-1916 on piers retained from an earlier (1869-1871) structure, to meet greater loading requirements from railroads that operated across the Mississippi at this point.

Project Development Information Packet for Federal-Aid City and County Projects, 1997

In August, 1994, the Office of Local Systems, Project Development Division, Iowa Department of Transportation established a Quality Improvement Team to review and improve upon the federal-aid project development process. The mission was to communicate federal-aid project development procedures to local agencies, beginning with the approval of the Statewide Transportation Improvement Program (STIP) and ending with obligation of federal funds by the Federal Highway Administration (FHWA). In January 1997, another Team (Make it Better) began meeting to clarify, update, and streamline the federal-aid project process. This Project Development Packet is a compilation of these efforts. The packet includes Project Development timelines, flow charts, guidelines, design criteria, Instructional Memorandums and forms to assist in the federal-aid project development process. The main (fold out) flow chart directs to other sections of the packet when appropriate.

Revised Iowa State Energy Conservation Plan : 1979 - 1980, 1979

The Revised Iowa Energy Conservation Plan: 1979-1980 is a blue print for the state's continued participation. The original Plan contained descriptions of more than 70 programs underway or conceived for state implementation with federal dollars. The Revised Plan contains only those programs to be funded in Federal dollars. The projects include five mandatory programs identified by DOE and several projects selected for funding by the Iowa Energy Policy Council (EPC), the policy making board which governs the state energy agency. The 18-member Council selected the conservation programs at its March 20-21, 1979 meeting. The Council retains the right to amend both the Plan and the budget at any time for the duration of the three-year program.

U.S. 63 Corridor Study, 1992

This report describes the U.S. 63 Corridor in terms of its economic and demographic features, the physical characteristics of the existing facility and the traffic it serves. Also, the various improvement alternatives are described and evaluated. These evaluations consider the traffic needs in the time period up to the year 2010, the travel benefits that would derive from alternative improvements to U.S. 63 and the economic development benefits that would be stimulated by such improvements. These benefits are related to the costs of the improvements and various indicators of economic feasibility are provided.

Upgrading Bridge Rails on Low-Volume Roads in Iowa, TR-679, 2016

Building on previous research, the goal of this project was to identify significant influencing factors for the Iowa Department of Transportation (DOT) to consider in future updates of its Instructional Memorandum (I.M.) 3.213, which provides guidelines for determining the need for traffic barriers (guardrail and bridge rail) at secondary roadway bridges—specifically, factors that might be significant for the bridge rail rating system component of I.M. 3.213. A literature review was conducted of policies and guidelines in other states and, specifically, of studies related to traffic barrier safety countermeasures at bridges in several states. In addition, a safety impact study was conducted to evaluate possible non-driver-related behavior characteristics of crashes on secondary road structures in Iowa using road data, structure data, and crash data from 2004 to 2013. Statistical models (negative binomial regression) were used to determine which factors were significant in terms of crash volume and crash severity. The study found that crashes are somewhat more frequent on or at bridges possessing certain characteristics—traffic volume greater than 400 vehicles per day (vpd) (paved) or greater than 50 vpd (unpaved), bridge length greater than 150 ft (paved) or greater than 35 ft (unpaved), bridge width narrower than its approach (paved) or narrower than 20 ft (unpaved), and bridges older than 25 years (both paved and unpaved). No specific roadway or bridge characteristic was found to contribute to more serious crashes. The study also confirmed previous research findings that crashes with bridges on secondary roads are rare, low-severity events. Although the findings of the study support the need for appropriate use of bridge rails, it concludes that prescriptive guidelines for bridge rail use on secondary roads may not be necessary, given the limited crash expectancy and lack of differences in crash expectancy among the various combinations of explanatory characteristics.

Brief Psychotherapy with Children in a Specialist School: An Exploration of the Underlying Issues for Children and Mainstream Schools

This thesis explores brief psychotherapy with children on placement at a specialist school setting, as part of an on-site, child psychotherapy outreach provision. The study sought to explore two research questions concerning the themes that could emerge in brief work with children and how these themes could be discussed in relation to the understanding formed by their mainstream school teachers. A qualitative research design was used to investigate these questions. The methods used to collect data were case studies, concerning the brief psychotherapy with 4 boys, aged 7 years, and and semi-structured interviews were conducted with the teachers. Thematic analysis was used to explore the data. The themes that were derived from the analysis were described in detail. The research found that brief work has considerable benefit for children and mainstream schools. Through the brief work intervention, the children all made significant progress in all areas of their lives a school. Contributions that the research makes to related fields, the implications that it has for policy and practice and recommendations for future research were all discussed.
