Defining the Attributes of Good In-Service Portland Cement Concrete Pavements, December 2004

Much of the current research in portland cement concrete (PCC) pavements deals with the analysis of early pavement life failures and seeks to find ways to prevent those from reoccurring. The Long Term Pavement Performance (LTPP) portion of the Strategic Highway Research Program (SHRP) has identified some of the key factors in designing and building new PCC pavements. This statement will build on the Iowa Highway Research Board (IHRB) project TR-463, Field Performance Study of Past Iowa Pavement Research: A Look Back. In Iowa and across the nation, there are multiple pavements that were built more than 20 years ago that have been and are continuing to provide very good service to the public. They are found on both state and local routes and in both low and high traffic volume areas. There is a need to learn what went into those pavements, from the subgrade through the surface, that makes them perform so well. The purpose of this research project was to conduct a scoping study that could be used to evaluate the need for additional research to study the attributes of well-performing concrete pavements. The concept of zero-maintenance jointed plain concrete pavements” was iterated in this study for long-lasting, well-performing portland cement concrete pavement sections. The scope of the study was limited to a brief literature survey, pavement performance data collection from many counties, cities, and primary and interstate roads in Iowa, field visits to many selected pavement sites, and analysis of the collected data. No laboratory orfield testing was conducted for this phase of the project. A problem statement with a research plan was created that could be used to guide the second phase of the project.

Blended Cements Improving Concrete Properties Using Environmentally Responsible Mixtures, December 2003

Recent research evaluated the behavior of concrete made with supplementary cementitious materials (SCMs) such as fly ash and ground granulated blast-furnace slag under a variety of conditions. Correlations were found among the source and proportion of the SCMs, curing conditions, concrete set time, maturity, strength development, and cracking potential.

State of Iowa HIV and AIDS Surveillance Report, December 2004

After taking a dip in 2003, HIV diagnoses were back up in 2004. There were 103 persons diagnosed in 2004, very close to our ten-year average of 100 cases per year. In 2003, there were 91 diagnoses. The increase in 2004 was limited to one demographic group: white, U.S.-born males. Most of these were men who have sex with men, but there were also small increases among injection-drug-using men and those without a known risk. Their median age was 41, slightly older than the overall median age of 38 years. Eighty percent were residents of the 10 most populous counties in Iowa, particularly the counties of Polk, Pottawattamie, Johnson, Linn, Scott, Story, and Woodbury.

State of Iowa HIV and AIDS Surveillance Report, December 2003

There were 33 new diagnoses of HIV infection reported in Iowa in the 4th quarter. Keeping in mind that more diagnoses will yet be reported for 2003, we have so far received reports of 79 Iowans who were newly diagnosed with HIV infection in 2003. Reports on persons diagnosed in the last quarter of the year will continue to trickle in through the end of March, but we’ll definitely be substantially below the 104 diagnoses we saw in 2002.

Library Services System for Iowa Library Services Task Force Report, December 2000

As a guide for librarians, library policy makers and the local level, community leaders, local and state policy makers, and library customers across the state, these recommendations create a vision of libraries as friendly, welcoming places where Iowans can access inform ation in person or on-lin e, ob tain, an d use ideas and truste d info rmatio n tha t will enhance their quality of life. This report specifies the steps to achieving this vision and creates an environment of opportunity to m ove s teadily toward the new system.
