The Effects of Crushed Particles in Asphalt Mixtures, HR-311 and MLR-88-16, Part 1, 1990

One of the most serious impediments to the continued successful use of hot mix asphalt (HMA) pavements is rutting. The Iowa Department of Transportation has required 85% crushed particles and 75 blow Marshall mix design in an effort to prevent rutting on interstate roadways. The objective of this research and report is to develop relation~hips between the percent of crushed particles and resistance to rutting in pavement through the use of various laboratory test procedures. HMA mixtures were made with 0, 30, 60, 85 and 100% crushed gravel, crushed limestone and crushed quartzite combined with uncrushed sand and gravel. These aggregate combinations were used with 4, 5 and 6% asphalt cement (ac). Laboratory testing included Marshall stability, resilient modulus, indirect tensile and creep. A creep resistance factor (CRF) was developed to provide a single numeric value for creep test results. The CRF values relate well to the amount of crushed particles and the perceived resistance to rutting. The indirect tensile test is highly dependent on the ac with a small effect from the percent of crushed particles. The Marshall stability from 75 blow compaction relates well to the percent of crushed particles. The resilient modulus in some cases is highly affected by grade of ac.

Identification of Practices, Design, Construction, and Repair Using Trenchless Technology, TR-570, 2010

Trenchless technologies are methods used for the construction and rehabilitation of underground utility pipes. These methods are growing increasingly popular due to their versatility and their potential to lower project costs. However, the use of trenchless technologies in Iowa and their effects on surrounding soil and nearby structures has not been adequately documented. Surveys of and interviews with professionals working in trenchless-related industries in Iowa were conducted, and the results were analyzed and compared to survey results from the United States as a whole. The surveys focused on method familiarity, pavement distress observed, reliability of trenchless methods, and future improvements. Results indicate that the frequency of pavement distress or other trenchless-related issues are an ongoing problem in the industry. Inadequate soil information and quality control/quality assurance (QC/QA) are partially to blame. Fieldwork involving the observation of trenchless construction projects was undertaken with the purpose of documenting current practices and applications of trenchless technology in the United States and Iowa. Field tests were performed in which push-in pressure cells were used to measure the soil stresses induced by trenchless construction methods. A program of laboratory soil testing was carried out in conjunction with the field testing. Soil testing showed that the installations were made in sandy clay or well-graded sand with silt and gravel. Pipes were installed primarily using horizontal directional drilling with pipe diameters from 3 to 12 inches. Pressure cell monitoring was conducted during the following construction phases: pilot bore, pre-reaming, and combined pipe pulling and reaming. The greatest increase in lateral earth pressure was 5.6 psi and was detected 2.1 feet from the centerline of the bore during a pilot hole operation in sandy lean clay. Measurements from 1.0 to 2.5 psi were common. Comparisons were made between field measurements and analytical and finite element calculation methods.

2015-16 Student Loan Repayment and Forgiveness Programs

Many loan repayment and incentive programs are available to encourage college students and graduates to enter into and continue to work in designated high-need careers. More and more Iowans are reaping the rewards of these federal, state and private programs that help reduce student loan debt while allowing them to pursue their career goals. Some programs make payments directly to the recipient’s student loan servicer to reduce the balance owed (loan repayment), while others may provide the option of an income stipend or bonus for eligible recipients who meet specified employment and other criteria. This guide provides information on many of the federal and state loan repayment and incentive programs currently available.

How to Apply for Financial Aid: A Guide for Students (2015-16)

Paying for college doesn’t have to be financially overwhelming. There are several types of aid, including federal, state and institutional grants; scholarships from numerous sources; college savings plans; student and parent loans; and student employment options available to help you pay for college. In fact, most students attending Iowa colleges and universities receive some form of financial assistance. To be considered for most financial aid programs, you must complete the Free Application for Federal Student Aid (FAFSA). Applying for admission is not the same as applying for financial aid - you need to do both. To receive financial aid, it is necessary to file a completed FAFSA and submit an admissions application to the colleges and universities that interest you most. Follow the steps in this brochure to be considered for funds from the state of Iowa, the federal government and the colleges or universities of your choice.

Your Course to College (2015-16)

This comprehensive guide, updated for the 2015-2015 academic year, provides financial aid information, as well as a directory of Iowa colleges and universities to assist students and families with the college selection process.
