Evaluation of Long-Term Field Performance of Cold In-Place Recycled Roads: Field Distress Survey, TR-502, 2007

Cold in-place recycling (CIR) has become an attractive method for rehabilitating asphalt roads that have good subgrade support and are suffering distress related to non-structural aging and cracking of the pavement layer. Although CIR is widely used, its use could be expanded if its performance were more predictable. Transportation officials have observed roads that were recycled under similar circumstances perform very differently for no clear reason. Moreover, a rational mix design has not yet been developed, design assumptions regarding the structural support of the CIR layer remain empirical and conservative, and there is no clear understanding of the cause-effect relationships between the choices made during the design/construction process and the resulting performance. The objective of this project is to investigate these relationships, especially concerning the age of the recycled pavement, cumulative traffic volume, support conditions, aged engineering properties of the CIR materials, and road performance. Twenty-four CIR asphalt roads constructed in Iowa from 1986 to 2004 were studied: 18 were selected from a sample of roads studied in a previous research project (HR-392), and 6 were selected from newer CIR projects constructed after 1999. This report summarizes the results of a comprehensive program of field distress surveys, field testing, and laboratory testing for these CIR asphalt roads. The results of this research can help identify changes that should be made with regard to design, material selection, and construction in order to lengthen the time between rehabilitation cycles and improve the performance and cost-effectiveness of future recycled roads.

This report describes the results of comprehensive field and laboratory testing for these CIR asphalt roads. The results indicate that the modulus of the CIR layer and the air voids of the CIR asphalt binder were the most important factors affecting CIR pavement performance for high-traffic roads. For low-traffic roads, the wet indirect tensile strength significantly affected pavement performance. The results of this research can help identify changes that should be made with regard to design, material selection, and construction in order to improve the performance and cost-effectiveness of future recycled roads.

Wireless Sensor Networks for Infrastructure Monitoring, TR-611, 2010

A good system of preventive bridge maintenance enhances the ability of engineers to manage and monitor bridge conditions, and take proper action at the right time. Traditionally infrastructure inspection is performed via infrequent periodical visual inspection in the field. Wireless sensor technology provides an alternative cost-effective approach for constant monitoring of infrastructures. Scientific data-acquisition systems make reliable structural measurements, even in inaccessible and harsh environments by using wireless sensors. With advances in sensor technology and availability of low cost integrated circuits, a wireless monitoring sensor network has been considered to be the new generation technology for structural health monitoring. The main goal of this project was to implement a wireless sensor network for monitoring the behavior and integrity of highway bridges. At the core of the system is a low-cost, low power wireless strain sensor node whose hardware design is optimized for structural monitoring applications. The key components of the systems are the control unit, sensors, software and communication capability. The extensive information developed for each of these areas has been used to design the system. The performance and reliability of the proposed wireless monitoring system is validated on a 34 feet span composite beam in slab bridge in Black Hawk County, Iowa. The micro strain data is successfully extracted from output-only response collected by the wireless monitoring system. The energy efficiency of the system was investigated to estimate the battery lifetime of the wireless sensor nodes. This report also documents system design, the method used for data acquisition, and system validation and field testing. Recommendations on further implementation of wireless sensor networks for long term monitoring are provided.

Iowa State Profile Tool: An Assessment of Iowa's Long-Term Support System, March 31, 2009

The Iowa State Profile Tool is a comprehensive, high-level assessment of Iowa’s progress toward a balanced long-term care system – a system that relies less on institutional services and provides greater opportunities for the in-home and community-based services that most people prefer. This report includes long-term support for people of all ages and disability types and is based on a variety of state and federal data sources and interviews with public and private leaders in Iowa’s long-term care system.

Involuntary Discharge from a Long-Term Facility

An involuntary discharge from a long-term care (LTC) facility occurs when the facility provides a 30-day written notice to a resident informing him/her of the need to move out of the facility. The notice must set out the reasons for the transfer or discharge as well as state the effective date, location of transfer or discharge, statement of appeal rights and the contact information (name, address and telephone number) for the Office of the State Long-Term Care Ombudsman.

Long-Term Care Choices

Consumers today have many choices when it comes to considering long-term care – whether they wish to remain in their home or community or move into an assisted living program or nursing home. Choosing a long-term care option that best fits your individual situation can depend on the level of care you need, your location preferences, your lifestyle needs and your ability to pay. The best time to begin exploring your options is long before the need arises. That way, you can communicate your preferences to your loved ones and create a plan that meets your needs as well as your wishes.

Long-term Care Payment Options

As the population ages, many of us will be faced with the prospect of moving either ourselves or a loved one into a long-term care setting (nursing home, assisted living facility or elder group home). Whether the decision comes up suddenly following a hospitalization or gradually as care needs evolve, the question of how to pay for long-term care is certain to arise. Some people mistakenly believe that Medicare will pay for their long-term care stay, but while Medicare will pay for hospital costs and skilled nursing facility stays, it does not pay for long-term care. Rather, possible payment options for long-term care include private pay, Medicaid or long-term care insurance or veterans benefits.

Sexuality Expression in Long-Term Care

By federal law, individuals residing in long-term care are afforded multiple rights, many of which are relevant to sexuality. These rights include but are not limited to: the rights to privacy, confidentiality, dignity and respect, the right to make independent choices, and the right to choose visitors and meet in a private location. The Office of the State Long-Term Care Ombudsman strives to preserve these rights by promoting attitudes of awareness, acceptance, and respect of sexual diversity. Though outcomes to sexually-related situations vary innumerably, as each is different and must be considered independently, the OSLTCO believes a multidisciplinary effort is necessary to develop a thoughtful process from which to draw and support conclusions. It is not the responsibility of the long-term care facility or assisted living program (or a single staff member) to solely determine whether a resident/tenant should or should not be sexually expressive.
