Evaluation of Transverse Joint Forming Methods for PCC Pavement, January 2006

The members of the Iowa Concrete Paving Association, the National Concrete Pavement Technology Center Research Committee, and the Iowa Highway Research Board commissioned a study to examine alternative ways of developing transverse joints in portland cement concrete pavements. The present study investigated six separate variations of vertical metal strips placed above and below the dowels in conventional baskets. In addition, the study investigated existing patented assemblies and a new assembly developed in Spain and used in Australia. The metal assemblies were placed in a new pavement and allowed to stay in place for 30 days before the Iowa Department of Transportation staff terminated the test by directing the contractor to saw and seal the joints. This report describes the design, construction, testing, and conclusions of the project.

Design Manual for Low Water Stream Crossings, October 1983

The purpose of this manual is to provide design guidelines for low water stream crossings (LWSCs). Rigid criteria for determining the applicability of a LWSC to a given site are not established since each site is unique in terms of physical, social, economic, and political factors. Because conditions vary from county to county, it is not the intent to provide a "cook-book" procedure for designing a LWSC. Rather, engineering judgment must be applied to the guidelines contained in this manual.

Iowa Pseudoephedrine Control Law, March 22, 2005

This law is intended to reduce the number of hazardous methamphetamine labs in Iowa, by controlling meth cooks’ access to the key meth-making ingredient: pseudoephedrine. In 2004, Iowa law enforcement agencies responded to a record 1,472 meth lab incidents. Below, please find links to: Senate File 169 (Iowa’s pseudoephedrine control law); an Iowa meth fact sheet; a brief overview of the law; and general compliance guidelines for consumers, pharmacies, retailers and law enforcement. Most provisions of this law, pertaining to pseudoephedrine sales, are effective May 21, 2005. However, two other provisions were effective immediately—March 22, 2005—upon the Governor’s signing of this measure into law: (1) removal of exceptions on the Schedule V Controlled Substance status for ephedrine [all ephedrine products now may only be sold in licensed pharmacies…no retail sales of ephedrine permitted]; and (2) addition of a requirement that bailable defendants charged with manufacture, delivery, possession with the intent to deliver, or distribution of methamphetamine, shall, in addition to a substance abuse evaluation, remain under supervision and be required to undergo random drug tests as a condition of release.

Nutrition & Wellness Programs for Older Iowans, June 20, 2012

Older Iowans are independent and want to stay that way – even in tough times. Good health is important to staying independent. Food Assistance can help you buy the groceries you need to stay healthy. Everyone deserves a nutritious meal. Food Assistance can help you buy foods that taste good and are good for you! Stay well for yourself and for your family. Call 2-1-1 and get connected to the Food Assistance office that serves your community. They can help you apply for an EBT card. The people who work in the Food Assistance Program really do care about your family’s health. Food Assistance is not a hand out . . . it’s a helping hand.

County grant program for veterans : status report on the implementation of 2006 Iowa Acts, Chapter 1185, Section 34, 2007

This is an overview of the program that the General Assembly of Iowa appropriated $1 million for to the Iowa Department of Veterans Affairs with the intent to improve delivery services by the various County Commissions of Veterans Affairs to veterans in their respective counties.

Impacts of Internal Curing on Concrete Properties, TR-676, 2015

Conventional concrete is typically cured using external methods. External curing prevents drying of the surface, allows the mixture to stay warm and moist, and results in continued cement hydration (Taylor 2014). Internal curing is a relatively recent technique that has been developed to prolong cement hydration by providing internal water reservoirs in a concrete mixture that do not adversely affect the concrete mixture’s fresh or hardened physical properties. Internal curing grew out of the need for more durable structural concretes that were resistant to shrinkage cracking. Joint spacing for concrete overlays can be increased if slab warping is reduced or eliminated. One of the most promising potential benefits from using internal curing for concrete overlays, then, is the reduced number of joints due to increased joint spacing (Wei and Hansen 2008).

Medicaid Home and Community Based Services Elderly Waiver Program

The Medicaid Home and Community Based Services (HCBS) Elderly Waiver program provides assistance to qualified individuals who are 65 or older and prefer to stay in their own home or another community setting when needing long-term health care services. The Elderly Waiver program provides services and support to older Iowans who are medically qualified for the level of care provided at a nursing facility but do not wish to live in a nursing home. The program allows older Iowans to age in environments that are familiar and comfortable, while saving money from expensive nursing home costs.

State Government Reorganization Commission, Answers and Recommendations to Select Information Technology Issues, 2009.

The State Government Reorganization Commission asked the Department of Administrative Services (DAS) to provide answers to questions pertaining to process improvements, and efficiencieswith the intent of reducing costs and discovering greater government efficiency.

Feasibility of Visualization and Simulation Applications to Improve Work Zone Safety and Mobility

Visualization is a relatively recent tool available to engineers for enhancing transportation project design through improved communication, decision making, and stakeholder feedback. Current visualization techniques include image composites, video composites, 2D drawings, drive-through or fly-through animations, 3D rendering models, virtual reality, and 4D CAD. These methods are used mainly to communicate within the design and construction team and between the team and external stakeholders. Use of visualization improves understanding of design intent and project concepts and facilitates effective decision making. However, visualization tools are typically used for presentation only in large-scale urban projects. Visualization is not widely accepted due to a lack of demonstrated engineering benefits for typical agency projects, such as small- and medium-sized projects, rural projects, and projects where external stakeholder communication is not a major issue. Furthermore, there is a perceived high cost of investment of both financial and human capital in adopting visualization tools. The most advanced visualization technique of virtual reality has only been used in academic research settings, and 4D CAD has been used on a very limited basis for highly complicated specialty projects. However, there are a number of less intensive visualization methods available which may provide some benefit to many agency projects. In this paper, we present the results of a feasibility study examining the use of visualization and simulation applications for improving highway planning, design, construction, and safety and mobility.
