Transportation Research Board 1920-1995 : 75 Years of Excellence...and IOWA was there from the beginning., 1995

"Certainly no one person or state was the sole impetus for something as monumental as the Highway Research Board. Yet Iowa boasts of having provided many of the key people whose vision and energies literally created and sustained the HRB during its first critical years: Anson Marston, Thomas Agg, Thomas MacDonald, and Roy Crum." -- from page 2

Action Plan: For implementing the recommendations of the Iowa Governor's Pre-White House Conference on Library and Information Services, April 30, May 1 and 2, 1991 and the White House Conference on Library and Information Services, July 9-13, 1991

This report includes the objectives, implementation responsibilities and target dates recommended and passed by the delegates to the Iowa Governor's Pre-White House Conference on Library and Information Services (April 30-May 2, 1991) or the White House Conference on Library and Information Services (July 9-13, 1991. Text of the relevant recommendations is included for each objective.

Iowa's frog and toad survey, 1995-2003.

This survey began in response to widespread interest of declines in amphibians. More recently, a comprehensive statewide planning group discovered 44% of Iowa’s herpetofauna (amphibians and reptiles) to be of special concern. In response to these concerns, the Iowa Department of Natural Resources Wildlife Diversity Program (WDP) initiated an auditory survey for calling anurans to determine geographic distributions within the state. This survey has established itself as an extensive, long term monitoring program. This 2005 report is the second edition since the first report of this survey was shared in 1998 by then program biologist Lisa Hemesath. The goals of the survey are to: (1) determine the distributions of Iowa’s anuran species, (2) determine population trends for each species, and (3) promote education about aquatic life by using volunteers to conduct the survey. In addition to Iowa, volunteer-based auditory surveys for frogs and toads are currently being used in the Midwest by Wisconsin, Minnesota, Missouri, and Illinois.

A plan for an electronic library and information services program for Iowa : presented to the Honorable Terry E. Branstad and members of the Iowa General Assembly, 1995

This document summarizes the conclusions and recommendations of the Library Services Advisory Council who were appointed by Governor Terry E. Branstad to develop a coordinated, cost-effective and comprehensive plan for the implementation of an electronic statewide library and information services program.

Transverse Joint Sealing with Improved Sealers, HR-276, 1991

Concern about premature joint sealant failures occurring in portland cement concrete (PCC) pavements gave impetus to initiating this research project. Eight sealants, including three silicone sealants, were evaluated and tested in the lab as well as incorporated in approximately 700 joints in the field and evaluated over a six-year period. The preliminary data show that among the silicone sealants, Dow Corning 888 rated the highest. However, this was rated third overall behind the W. R. Meadows cold-applied Sof Seal and Crafco #231 hot pour sealants. The W. R. Meadows and Crafco sealants cost approximately 30 percent and 50 percent less to furnish and place than the Dow Corning product. All joint sealants will continue to be evaluated.

Relating Creep Testing to Rutting of Asphalt Concrete Mixes, HR-311, Part 2, 1991

The Iowa Department of Transportation began creep and resilient modulus testing of asphalt concrete mixtures in 1989. Part 1 of this research reported in January 1990 was a laboratory study of hot mix asphalt (HMA) mixtures made with O, 30, 60, 85 and 100% crushed gravel, crushed limestone and crushed quartzite combined with uncrushed sand and gravel. Creep test results from Marshall specimens related well to the percent of crushed particles and the perceived resistance to rutting. The objective of this research, part 2, was to determine if there was a meaningful correlation between pavement rut depth and the resilient modulus or the creep resistance factor. Four and six inch diameter cores were drilled from rutted primary and interstate pavements and interstate pavements with design changes intended to resist rutting. The top 2 1/2 inches of each core, most of which was surface course, was used for creep and resilient modulus testing. There is a good correlation between the resilient modulus of four and six inch diameter cores. Creep resistance factors of four and six inch diameter cores also correlated well. There is a poor correlation between resilient modulus and the creep resistance factor. The rut depth per million 18,000 pound equivalent single axle loadings (ESAL) for these pavements did not correlate well with either the resilient modulus or the creep resistance factor.

Self Instructional Math, HR-324, 1995

The Self Instructional Math course book is designed to provide a basic math knowledge for those involved in the planning, design, and construction of highways. It was developed in a manner to allow the student to take the course with minimal supervision and at times that the work schedule allows. The first version of the course was developed in the early 1970's and due to its popularity was revised in the early 1990's to reflect changes in the highway construction math needs. The anticipated move to metric (System International) measurements by the highway industry has necessitated the need to change the math course problem values to metric units. The course includes the latest in Iowa DOT policy information relative to the selection and use of metric values for highway design, and construction. Each unit of the book contains instructional information, section quizzes and a comprehensive examination. All problem values are expressed in metric rather than dual (english and SI) units. The appendix contains useful conversion factors to assist the reader in making the change to metric.
