Dowel Bar Optimization: Phases I and II, October 2001

America’s roadways are in serious need of repair. According to the American Society of Civil Engineers (ASCE), one-third of the nation’s roads are in poor or mediocre condition (1). ASCE has estimated that under these circumstances American drivers will sacrifice $5.8 billion and as many as 13,800 fatalities a year from 1999 to 2001 ( 1). A large factor in the deterioration of these roads is a result of how well the steel reinforcement transfers loads across the concrete slabs. Fabricating this reinforcement using a shape conducive to transferring these loads will help to aid in minimizing roadway damage. Load transfer within a series of concrete slabs takes place across the joints. For a typical concrete paved road, these joints are approximately 1/8-inch gaps between two adjacent slabs. Dowel bars are located at these joints and used to transfer load from one slab to its adjacent slabs. As long as the dowel bar is completely surrounded by concrete no problems will occur. However, when the hole starts to oblong a void space is created and difficulties can arise. This void space is formed due to a stress concentration where the dowel contacts the concrete. Over time, the repeated process of traffic traveling over the joint crushes the concrete surrounding the dowel bar and causes a void in the concrete. This void inhibits the dowel’s ability to effectively transfer load across the joint. Furthermore, this void gives water and other particles a place to collect that will eventually corrode and potentially bind or lock the joint so that no thermal expansion is allowed. Once there is no longer load transferred across the joint, the load is transferred to the foundation and differential settlement of the adjacent slabs will occur.

The Americans with Disabilities Act Employer/Employee Rights & Responsibilities, May 2001

This publication was designed with the belief that the ADA addresses both employers and employees to achieve a viable workforce and productive society. The law was intended to reflect the balance between the employer and the employee with a disability. This booklet contains information on Title I of the ADA but should not be considered legal advice. Title I is directly related to the employment provisions of the law. Both employers and employees have responsibilities and rights under the ADA and this booklet addresses the balance of rights and responsibilities under the law. This law was designed to remove the barriers that prevent qualified persons from enjoying equal employment opportunities solely because of a disability. It demonstrates America recognizing the vitality and abilities of all people to contribute in our society, particularly in the area of employment. This is civil rights law. It prohibits discrimination against persons with disabilities and encourages the recognition of citizens with disabilities as full participants in American life. It recognizes that these members of the American work force are an excellent resource for employers.

Report of the Governor's Task Force on the Overepresentation of African-Americans in Prison, 2001

In 1999, 24 percent of Iowa prison beds were occupied by African-American inmates, despite the fact that African-Americans comprised just over 2 percent of the state’s total population. That year the median incarceration rate for African-Americans in Iowa was 2,950 per every 100,000 people (or approximately 3.0 percent of the state’s African-American population). The median incarceration rate for Caucasians in Iowa was 188 per every 100,000 people (or approximately 0.2 percent of the state’s Caucasian population). Seven percent of all African-Americans in this state were under some form of criminal justice supervision in 1999. 1999 statistics also reveal that there were nearly twice as many African-Americans under criminal justice supervision in Iowa than atte nded one of the state’s post-secondary institutions.
